COMPOSITIONS FOR AND METHODS OF ENGINEERING THE TRANSCRIPTOMEI. CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 549,494 filed 3 February 2024 and U.S. Provisional Application No. 63 / 571,441 filed 29 March 2024, each of which is incorporated herein in its entirety.II. REFERENCE TO THE SEQUENCE LISTING

[0002] The Sequence Listing submitted 3 February 2025 as an XML file named “24-3010-WO- Sequence-Listing”, created on 3 February 2025 and having a size of 204,800 bytes is hereby incorporated by reference pursuant to 37 C.F.R. § 1.52(e)(5).III. BACKGROUND

[0003] The cellular RNA processing machinery has many attributes that can be exploited to manipulate the transcriptome. Specifically, RNA splicing is well conserved in higher eukaryotes and executed by a large ribonucleoprotein complex called the spliceosome. The canonical function of the spliceosome is to catalyze a dual trans-esterification reaction, that joins adjacent exons on the same transcript and removes the intervening intronic sequence; a process referred to as cis-splicing. This splicing machinery has been previously exploited to achieve mRNA transsplicing, which involves targeted incorporation of recombinant exon or exons into a pre-mRNA transcript. This approach features an RNA molecule comprised of an antisense sequence linked to a hemi-intron and one or more exons. Following delivery to the nucleus, the hybridization of the antisense binding domain to the target pre-mRNA enables the intronic sequence to incorporate the recombinant exons in trans by co-opting the splicing machinery, resulting in a chimeric mRNA product. This process has been enhanced through combination with next generation RNA targeting systems such as CRISPR / Casl3.

[0004] One bottleneck to the translation of technologies is optimizing the editing efficiency at a given target. Testing out individual variations of trans-splicing platforms is laborious and can become unwieldy quickly due to the vast parameter space that exists for such technologies (i.e., guide position, guide length, guide number, intron composition, untranslated regions, RNA binding protein recruitment domains, etc.). These efforts are further complicated by the transient nature of RNA editing, and that the region of the trans-splicing RNA responsible for catalyzing editing is not preserved in the final edited product (i.e., the guide is in the intron that undergoes splicing and as such is not a part of the mature RNA). Thus, a pooled approach to screen guide candidates is used, it is not possible to discern from the mature RNA which guide was responsible for trans-splicing.

[0005] Thus, there remains an urgent need for a means to ascertain the efficacy of RNA guides and targeting motifs in a trans-splicing event. Consequently, the present disclosure provides compositions for and methods of identifying effective RNA guides and targeting motifs.IV. BRIEF DESCRIPTION OF THE FIGURES

It is understood that treatment does not necessarily refer to a cure or complete ablation or eradication of a disease or disorder. However, in an aspect, treatment can refer to a cure or complete ablation or eradication of a disease or disorder.

[0082] As used herein, the term “prevent” or “preventing” or “prevention” refers to precluding, averting, obviating, forestalling, stopping, or hindering something from happening, especially by advance action. It is understood that where reduce, inhibit, or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed. In an aspect, preventing a disease or disorder having chromatin deregulation and / or chromatin dysregulation is intended. The words “prevent”, “preventing”, and “prevention” also refer to prophylactic or preventative measures for protecting or precluding a subject (e.g., an individual) not having a given a disease or disorder (such as a genetic disease or disorder) or related complication from progressing to that complication.

[0083] As used herein, the terms “administering” and “administration” refer to any method of providing one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof to a subject. Such methods are well known to those skilled in the art and include, but are not limited to, the following: oral administration, transdermal administration, administration by inhalation, nasal administration, topical administration, in utero administration, intrahepatic administration, intravaginal administration, ophthalmic administration, intraaural administration, otic administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injectable such as intravenous administration, intra-CSF administration, intra-arterial administration, intramuscular administration, and subcutaneous administration. Administration can also include hepatic intra-arterial administration or administration through the hepatic portal vein (HPV). Administration of a disclosed nucleic acidmolecule, a disclosed vector, a disclosed pharmaceutical composition, a disclosed therapeutic agent, a disclosed immune modulator, a disclosed proteasome inhibitor, a disclosed small molecule, a disclosed endonuclease, a disclosed oligonucleotide, and / or a disclosed RNA therapeutic can comprise administration directly into the CNS or the PNS. Administration can be continuous or intermittent. Administration can comprise a combination of one or more route.

[0084] In an aspect, the skilled person can determine an efficacious dose, an efficacious schedule, and an efficacious route of administration for one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof to treat or prevent a disease or disorder (such as genetic disease or disorder). In an aspect, the skilled person can also alter, change, or modify an aspect of an administering step to improve efficacy of one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof.

[0085] By “determining the amount” is meant both an absolute quantification of a particular analyte (e.g., an mRNA sequence containing a particular tag) or a determination of the relative abundance of a particular analyte (e.g., an amount as compared to a mRNA sequence including a different tag). The phrase includes both direct or indirect measurements of abundance (e.g., individual mRNA transcripts may be quantified or the amount of amplification of an mRNA sequence under certain conditions for a certain period may be used a surrogate for individual transcript quantification) or both.

[0086] As used herein, “modifying the method” can comprise modifying or changing one or more features or aspects of one or more steps of a disclosed method. For example, in an aspect, a method can be altered by changing the amount of one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof administered to a subject, or by changing the frequency of administration of one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof to a subject, by changing the duration of time one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination are administered to a subject, or by substituting for one or more of the disclosed components and / or reagents with a similar or equivalent component and / or reagent. The same applies to all disclosed therapeutic agents, immune modulators, immunosuppressive agents, proteosome inhibitors, etc.

[0087] As used herein, the term “pharmaceutically acceptable carrier” refers to sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitableaqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. In an aspect, a pharmaceutical carrier employed can be a solid, liquid, or gas. In an aspect, examples of solid carriers can include lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, and stearic acid. In an aspect, examples of liquid carriers can include sugar syrup, peanut oil, olive oil, and water. In an aspect, examples of gaseous carriers can include carbon dioxide and nitrogen. In preparing a disclosed composition for oral dosage form, any convenient pharmaceutical media can be employed. For example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like can be used to form oral liquid preparations such as suspensions, elixirs and solutions; while carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like can be used to form oral solid preparations such as powders, capsules and tablets. Because of their ease of administration, tablets and capsules are the preferred oral dosage units whereby solid pharmaceutical carriers are employed. Optionally, tablets can be coated by standard aqueous or nonaqueous techniques. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions can also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents such as paraben, chlorobutanol, phenol, sorbic acid and the like. It can also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents, such as aluminum monostearate and gelatin, which delay absorption. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide, poly(orthoesters) and poly(anhydrides). Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable media just prior to use. Suitable inert carriers can include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers.

[0088] As used herein, the term “excipient” refers to an inert substance which is commonly used as a diluent, vehicle, preservative, binder, or stabilizing agent, and includes, but is not limited to, proteins (e.g., serum albumin, etc.), amino acids (e.g., aspartic acid, glutamic acid, lysine, arginine, glycine, histidine, etc.), fatty acids and phospholipids (e.g., alkyl sulfonates, caprylate, etc.), surfactants (e.g., SDS, polysorbate, nonionic surfactant, etc.), saccharides (e.g., sucrose, maltose, trehalose, etc.) and polyols (e.g., mannitol, sorbitol, etc.). See, also, for reference, Remington’s Pharmaceutical Sciences, (1990) Mack Publishing Co., Easton, Pa., which is hereby incorporated by reference in its entirety.

[0089] As used herein, “concurrently” means (1) simultaneously in time, or (2) at different times during the course of a common treatment schedule.

[0090] The term “contacting” as used herein refers to bringing one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof together with a target area or intended target area in such a manner that the one or more of the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations, or a combination thereof exert an effect on the intended target or targeted area either directly or indirectly. A target area can comprise one or more cells, and in an aspect, one or more cells can be in a subject. A target area or intended target area can be one or more of a subject’s organs (e.g., lungs, heart, liver, kidney, brain, etc.). In an aspect, a target area or intended target area can be any cell or any organ infected by a disease or disorder (such as a genetic disease or disorder). In an aspect, a target area or intended target area can be any organ, tissue, or cells that are affected by a disease or disorder (such as a genetic disease or disorder).

[0091] As used herein, “determining” can refer to measuring or ascertaining the presence and severity of a disease or disorder, such as, for example, a genetic disease or disorder. Methods and techniques used to determine the presence and / or severity of a disease or disorder are typically known to the medical arts. For example, the art is familiar with the ways to identify and / or diagnose the presence, severity, or both of a disease or disorder (such as, for example, a genetic disease or disorder).

[0092] As used herein, “effective amount” and “amount effective” can refer to an amount that is sufficient to achieve the desired result such as, for example, the treatment and / or prevention of a disease or disorder (e.g., a genetic disease or disorder) or a suspected disease or disorder. As used herein, the terms “effective amount” and “amount effective” can refer to an amount that is sufficient to achieve the desired an effect on an undesired condition e.g., a disease or disorder). For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generallyinsufficient to cause adverse side effects. In an aspect, “therapeutically effective amount” means an amount of a disclosed nucleic acid molecule, a disclosed vector, or a disclosed pharmaceutical formulation; that (i) treats the particular disease, condition, or disorder (e.g., a genetic disease or disorder), (ii) attenuates, ameliorates, or eliminates one or more symptoms of the particular disease, condition, or disorder e.g., a genetic disease or disorder), or (iii) delays the onset of one or more symptoms of the particular disease, condition, or disorder described herein (e.g., a genetic disease or disorder). The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the disclosed nucleic acid molecules, disclosed vectors, disclosed pharmaceutical formulations employed; the disclosed methods employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the disclosed nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations employed; the duration of the treatment; drugs used in combination or coincidental with the disclosed nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations employed, and other like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of the disclosed nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, then the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, a single dose of the disclosed nucleic acid molecules, disclosed vectors, or disclosed pharmaceutical formulations can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition, such as, for example, a disease or disorder due to a missing, deficient, and / or mutant protein or enzyme.

[0093] As used herein, “RNA therapeutics” can refer to the use of oligonucleotides to target RNA. RNA therapeutics can offer the promise of uniquely targeting the precise nucleic acids involved in a particular disease with greater specificity, improved potency, and decreased toxicity. This could be particularly powerful for genetic diseases where it is most advantageous to aim for the RNA as opposed to the protein. In an aspect, a therapeutic RNA can comprise one or more expression sequences. As known to the art, expression sequences can comprise an RNAi, shRNA,mRNA, non-coding RNA (ncRNA), an antisense such as an antisense RNA, miRNA, morpholino oligonucleotide, peptide-nucleic acid (PNA) or ssDNA (with natural, and modified nucleotides, including but not limited to, LNA, BNA, 2’-0-Me-RNA, 2’-ME0-RNA, 2’-F-RNA), or analog or conjugate thereof. In an aspect, a disclosed therapeutic RNA can comprise one or more long non-coding RNA (IncRNA), such as, for example, a long intergenic non-coding RNA (lincRNA), pre-transcript, pre-miRNA, pre-mRNA, competing endogenous RNA (ceRNA), small nuclear RNA (snRNA), small nucleolar RNA (snoRNA), pseudo-gene, rRNA, or tRNA. In an aspect, ncRNA can be pi wi -interacting RNA (piRNA), primary miRNA (pri-miRNA), or premature miRNA (pre-miRNA). In an aspect, a disclosed therapeutic RNA or an RNA therapeutic can comprise antisense oligonucleotides (ASOs) that inhibit mRNA translation, oligonucleotides that function via RNA interference (RNAi) pathway, RNA molecules that behave like enzymes (ribozymes), RNA oligonucleotides that bind to proteins and other cellular molecules, and ASOs that bind to mRNA and form a structure that is recognized by RNase H resulting in cleavage of the mRNA target. In an aspect, RNA therapeutics can comprise RNAi and ASOs that inhibit mRNA translation. Generally speaking, as known to the art, RNAi operates sequence specifically and post-transcriptionally by activating ribonucleases which, along with other enzymes and complexes, coordinately degrade the RNA after the original RNA target has been cut into smaller pieces while antisense oligonucleotides bind to their target nucleic acid via Watson-Crick base pairing, and inhibit or alter gene expression via steric hindrance, splicing alterations, initiation of target degradation, or other events.

[0094] As used herein, “small molecule” can refer to any organic or inorganic material that is not a polymer. Small molecules exclude large macromolecules, such as large proteins (e.g., proteins with molecular weights over 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, or 10,000), large nucleic acids (e.g., nucleic acids with molecular weights of over 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, or 10,000), or large polysaccharides (e.g., polysaccharides with a molecular weight of over 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, or 10,000). In an aspect, a “small molecule”, for example, can be a drug that can enter cells easily because it has a low molecular weight. In an aspect, a small molecule can be used in conjunction with a disclosed composition in a disclosed method.

[0095] In an aspect, the term “ex vivo” can refer generally to activities that take place outside an organism or subject such as experimentation, modification, differentiation, manipulation, and / or measurement done in or on living tissue in an artificial environment outside the organism. In an aspect, ex vivo experimentation, ex vivo modification, ex vivo differentiation, ex vivo manipulation, and / or ex vivo measurement can occur with a minimum alteration of the naturalconditions. In an aspect, “ex vivo” can comprise living cells, tissues, or organs (e.g., cells in need of trans-splicing for one or more protein coding genes) taken from a subject in need thereof or a donor subject and cultured and / or maintained and / or perfused in a laboratory apparatus, usually under sterile conditions, and typically for a limited duration of time (e.g., a few hours or up to about 24 hours, up to about 48 hours, up to about 72 hours, up to about 96 hours, up to about 120 hours, up to about 144 hours, up to about 168 hours, or more depending on the circumstances and / or the desired characteristics. In an aspect, tissues, cells, or organs can be collected, frozen, and later thawed for ex vivo treatment.

[0096] As used herein, “operably linked” means that expression of a gene or a transgene is under the control of a promoter with which it is spatially connected. A promoter can be positioned 5’ (upstream) or 3’ (downstream) of a gene under its control. The distance between the promoter and a gene can be approximately the same as the distance between that promoter and the gene it controls in the gene from which the promoter is derived. As is known in the art, variation in this distance can be accommodated without loss of promoter function.

[0097] As used herein, “peptide,” “polypeptide,” and “protein” are used interchangeably, and refer to a compound comprised of amino acid residues covalently linked by peptide bonds. A protein must contain at least two amino acids and there is no limitation on the maximum number of amino acids that can comprise a protein’s sequence. The term “peptide” can refer to a short chain of amino acids including, for example, natural peptides, recombinant peptides, synthetic peptides, or any combination thereof. Proteins and peptides can include, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, variants of polypeptides, modified polypeptides, derivatives, analogs, and fusion proteins, among others.

[0098] “Nucleic acid” or “oligonucleotide” or “polynucleotide” as used herein means at least two nucleotides covalently linked together. The depiction of a single strand can also define the sequence of the complementary strand. Thus, a nucleic acid can encompass the complementary strand of a depicted single strand. Many variants of a nucleic acid can be used for the same purpose as a given nucleic acid. Thus, a nucleic acid can encompass substantially identical nucleic acids and complements thereof. A single strand can provide a probe that can hybridize to a target sequence under stringent hybridization conditions. Thus, a nucleic acid can encompass a probe that hybridizes under stringent hybridization conditions. A nucleic acid can be single-stranded, or double-stranded, or can contain portions of both double-stranded and single-stranded sequence. The nucleic acid can be DNA, both genomic and cDNA, RNA, or a hybrid, where the nucleic acid can contain combinations of deoxyribo- and ribo-nucleotides, and combinations of bases includinguracil, adenine, thymine, cytosine, guanine, inosine, xanthine hypoxanthine, isocytosine and isoguanine. Nucleic acids can be obtained by chemical synthesis methods or by recombinant methods. Also as used herein, the terms “nucleic acid,” “nucleic acid molecule,” “nucleic acid construct,” “nucleotide sequence”, and “polynucleotide” can refer to RNA or DNA that is linear or branched, single or double stranded, or a hybrid thereof. The term can encompass RNA / DNA hybrids. When dsRNA is produced synthetically, less common bases, such as inosine, 5- methylcytosine, 6-methyladenine, hypoxanthine and others can also be used for antisense, dsRNA, and ribozyme pairing. For example, polynucleotides that contain C-5 propyne analogues of uridine and cytidine have been shown to bind RNA with high affinity and to be potent antisense inhibitors of gene expression. Other modifications, such as modification to the phosphodiester backbone, or the 2’ -hydroxy in the ribose sugar group of the RNA can also be made. A “synthetic” nucleic acid or polynucleotide, as used herein, refers to a nucleic acid or polynucleotide that is not found in nature but is constructed by the hand of man and therefore is not a product of nature.

[0099] A “polynucleotide” is a sequence of nucleotide bases, and may be RNA, DNA, or DNA- RNA hybrid sequences (including both naturally occurring and non-naturally occurring nucleotides).

[0100] A “fragment” or “portion” of a nucleotide sequence can be understood to mean a nucleotide sequence of reduced length relative (e.g., reduced by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,13, 14, 15, 16, 17, 18, 19, 20 or more nucleotides) to a reference nucleic acid or nucleotide sequence and comprising, consisting essentially of, or consisting of a nucleotide sequence of contiguous nucleotides identical or almost identical (e.g., 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% identical) to the reference nucleic acid or nucleotide sequence. Such a nucleic acid fragment or portion according to the disclosure can be, where appropriate, included in a larger polynucleotide of which it is a constituent. In an aspect, a fragment or portion of a nucleotide sequence or nucleic acid sequence can comprise the sequence encoding an exon having one or more mutations.

[0101] A “fragment” or “portion” of an amino acid sequence can be understood to mean an amino acid sequence of reduced length relative (e.g., reduced by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,14, 15, 16, 17, 18, 19, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, or more amino acids) to a reference amino acid sequence and comprising, consisting essentially of, or consisting of an amino acid sequence of contiguous amino acids identical or almost identical (e.g., 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% identical) to the reference aminoacid sequence. Such an amino acid fragment or portion according to the disclosure can be, where appropriate, included in a larger amino acid sequence of which it is a constituent.

[0102] A “heterologous” or a “recombinant” nucleotide or amino acid sequence as used interchangeably herein can refer to a nucleotide or an amino acid sequence not naturally associated with a host cell into which it is introduced, including non-naturally occurring multiple copies of a naturally occurring nucleotide or amino acid sequence.

[0103] As used herein, the term “endogenous” can refer to a gene, protein, compound, or activity that is normally present in a host cell (e.g., a pre-mRNA). As used herein, an “exogenous” nucleic acid molecule, construct, or sequence (e.g., an RNA sequence to be trans-spliced) can refer to a nucleic acid molecule or portion of a nucleic acid molecule that is not native to a host cell, but may be homologous to a nucleic acid molecule or portion of a nucleic acid molecule from the host cell.

[0104] Different nucleic acids or proteins having homology can be referred to as “homologues”. The term homologue includes homologous sequences from the same and other species and orthologous sequences from the same and other species. “Homology” refers to the level of similarity between two or more nucleic acid and / or amino acid sequences in terms of percent of positional identity (i.e., sequence similarity or identity). Homology also refers to the concept of similar functional properties among different nucleic acids or proteins. Thus, the disclosed compositions and disclosed methods can comprise homologues to the disclosed nucleotide sequences and / or disclosed polypeptide sequences.

[0105] “Orthologous,” as used herein, can refer to homologous nucleotide sequences and / or amino acid sequences in different species that arose from a common ancestral gene during speciation. A homologue of a disclosed nucleotide sequence or a disclosed polypeptide can have substantial sequence identity (e.g., at least about 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, and / or 100%) to a disclosed nucleotide sequence or a disclosed polypeptide.

[0106] “Complement” or “complementary” as used herein means a nucleic acid can mean Watson-Crick (e.g., A-T / U and C-G) or Hoogsteen base pairing between nucleotides or nucleotide analogs of nucleic acid molecules. “Complementarity” refers to a property shared between two nucleic acid sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position will be complementary.

[0107] As used herein, “promoter” or “promoters” are known to the art. Depending on the level and tissue-specific expression desired, a variety of promoter elements can be used. A promotercan be tissue-specific or ubiquitous and can be constitutive or inducible, depending on the pattern of the gene expression desired. A promoter can be native (endogenous) or foreign (exogenous) and can be a natural or a synthetic sequence. By foreign or exogenous, it is intended that the transcriptional initiation region is not found in the wild-type host into which the transcriptional initiation region is introduced.

[0108] “Tissue-specific promoters” are known to the art and include, but are not limited to, neuron-specific promoters, muscle-specific promoters, liver-specific promoters, skeletal musclespecific promoters, and heart-specific promoters.

[0109] “Liver-specific promoters” are known to the art and include, but are not limited to, the thyroxin binding globulin (TBG) promoter, the al-microglobulin / bikunin enhancer / thyroid hormone-binding globulin promoter, the human albumin (hALB) promoter, the thyroid hormone- binding globulin promoter, the a- 1 -anti -trypsin promoter, the bovine albumin (bAlb) promoter, the murine albumin (mAlb) promoter, the human al -antitrypsin (hAAT) promoter, the ApoEhAAT promoter comprising the ApoE enhancer and the hAAT promoter, the transthyretin (TTR) promoter, the liver fatty acid binding protein promoter, the hepatitis B virus (HBV) promoter, the DC 172 promoter comprising the hAAT promoter and the al -microglobulin enhancer, the DC 190 promoter comprising the human albumin promoter and the prothrombin enhancer, or any other natural or synthetic liver-specific promoter. In an aspect, a liver specific promoter can comprise about 845-bp and comprise the thyroid hormone-binding globulin promoter sequences (2382 to 13), two copies of al-microglobulin / bikunin enhancer sequences (22,804 through 22,704), and a 71-bp leader sequence as described by Ill CR, et al. (1997).

[0110] Ubiquitous / constitutive promoters” are known to the art and include, but are not limited to, a CMV major immediate-early enhancer / chicken beta-actin promoter, a cytomegalovirus (CMV) major immediate-early promoter, an Elongation Factor 1-a (EFl -a) promoter, a simian vacuolating virus 40 (SV40) promoter, an AmpR promoter, a PyK promoter, a human ubiquitin C gene (Ubc) promoter, a MFG promoter, a human beta actin promoter, a CAG promoter, a EGR1 promoter, a FerH promoter, a FerL promoter, a GRP78 promoter, a GRP94 promoter, a HSP70 promoter, a [3-kin promoter, a murine phosphoglycerate kinase (mPGK) or human PGK (hPGK) promoter, a ROSA promoter, human Ubiquitin B promoter, a Rous sarcoma virus promoter, or any other natural or synthetic ubiquitous / constitutive promoters.

[0111] As used herein, an “inducible promoter” refers to a promoter that can be regulated by positive or negative control. Factors that can regulate an inducible promoter include, but are not limited to, chemical agents (e.g., the metallothionein promoter or a hormone inducible promoter), temperature, and light.

[0112] As used herein, the term “serotype” is a distinction used to refer to an AAV having a capsid that is serologically distinct from other AAV serotypes. Serologic distinctiveness can be determined by the lack of cross-reactivity between antibodies to one AAV as compared to another AAV. Such cross-reactivity differences are usually due to differences in capsid protein sequences / antigenic determinants (e.g., due to VP1, VP2, and / or VP3 sequence differences of AAV serotypes).

[0113] As used herein, “tropism” refers to the specificity of an AAV capsid protein present in an AAV viral particle, for infecting a particular type of cell or tissue. The tropism of an AAV capsid for a particular type of cell or tissue may be determined by measuring the ability of AAV vector particles comprising the hybrid AAV capsid protein to infect or to transduce a particular type of cell or tissue, using standard assays that are well-known in the art such as those disclosed in the examples of the present application. As used herein, the term “liver tropism” or “hepatic tropism” refers to the tropism for liver or hepatic tissue and cells, including hepatocytes.

[0114] “Sequence identity” and “sequence similarity” can be determined by alignment of two peptide or two nucleotide sequences using global or local alignment algorithms. Sequences may then be referred to as “substantially identical” or “essentially similar” when they are optimally aligned. For example, sequence similarity or identity can be determined by searching against databases such as FASTA, BLAST, etc., but hits should be retrieved and aligned pairwise to compare sequence identity. Two proteins or two protein domains, or two nucleic acid sequences can have “substantial sequence identity” if the percentage sequence identity is at least 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99% or more, preferably 90%, 95%, 98%, 99% or more. Such sequences are also referred to as “variants” herein, e.g., other variants of a missing, deficient, and / or mutant protein or enzyme. It should be understood that sequence with substantial sequence identity do not necessarily have the same length and may differ in length. For example, sequences that have the same nucleotide sequence but of which one has additional nucleotides on the 3’- and / or 5’-side are 100% identical.

[0115] As used herein, “codon optimization” can refer to a process of modifying a nucleic acid sequence for enhanced expression in the host cells of interest by replacing one or more codons or more of the native sequence with codons that are more frequently or most frequently used in the genes of that host cell while maintaining the native amino acid sequence. Various species exhibit particular bias for certain codons of a particular amino acid. As contemplated herein, genes can be tailored for optimal gene expression in a given organism based on codon optimization. Codon usage tables are readily available, for example, at the “Codon Usage Database.” Many methodsand software tools for codon optimization have been reported previously. (See, for example, genomes.urv.es / OPTIMIZER / ).

[0116] As used herein, “CRISPR or clustered regularly interspaced short palindromic repeat” is an ideal tool for correction of genetic abnormalities as the system can be designed to target genomic DNA directly. Cas9 is well-known to the art. The CRISPR / Cas methods disclosed herein, such as those that use an Cast 3d, can be used to edit the sequence of one or more target RNAs, such as one associated with a disease or disorder disclosed herein (e.g., a genetic disease or disorder).

[0117] The diverse Casl3 family contains at least four known subtypes, including Casl3a (formerly C2c2), Cast 3b, Cast 3 c, and Cast 3d. All known Cast 3 family members contain two HEPN domains, which confer RNase activity. Casl3 can be reprogrammed to cleave a targeted ssRNA molecule through a short guide RNA with complementarity to the target sequence. Cas 13s function similarly to Cas9, using a ~64-nucleotide guide RNA to encode target specificity. The Cas 13 protein complexes with the guide RNA via recognition of a short hairpin in the crRNA, and target specificity is encoded by a 28-nucleotide to a 30-nucleotide spacer that is complementary to the target region. In addition to programmable RNase activity, all Casl3s exhibit collateral activity after recognition and cleavage of a target transcript, leading to nonspecific degradation of any nearby transcripts regardless of complementarity to the spacer. While Cas 13a showed some activity for RNA knockdown, certain orthologs of Cas 13b proved more stable and robust in mammalian cells for RNA knockdown and editing. More recently, additional orthologs of Casl3 have been discovered, including Casl3d, which has been leveraged for efficient and robust knockdown across many endogenous transcripts. Casl3d can be used to modulate splicing of endogenous transcripts and that the coding sequence for Casl3d is small enough to fit within the packaging limits of AAV for in vivo delivery.

[0118] In an aspect, Cas 13 can be considered an outlier in the CRISPR world because it targets RNA, not DNA. Once it is activated by a ssRNA sequence bearing complementarity to its crRNA spacer, it unleashes a nonspecific RNase activity and destroys all nearby RNA regardless of their sequence. As disclosed herein, this property can be harnessed in vitro for precision diagnostics. Generally, Casl3 can be found in Leptotrichia buccalis, Leptotrichia shahii, Ruminococcus flavefaciens, Bergeyella zoohelcum, Prevotella buccae, and Listeria seeligeri and can have a size of about 900 to about 1300 amino acids. In an aspect, the guide spacer length can be about 22 to about 30 nucleotides while the total guide length can be about 52 to about 66 nucleotides. In an aspect, a PAM can be 3-H for LshCasl3a, 5-D and 3-NAN or NNA for BzCasl3b, and none for RfCasl3d. In an aspect, a disclosed Casl3 can cut ssRNA.

[0119] As known to the skilled person in the cart, a Casl3d ortholog can be from a prokaryotic genome or metagenome, gut metagenome, an activated sludge metagenome, an anaerobic digester metagenome, a chicken gut metagenome, a human gut metagenome, a pig gut metagenome, a bovine gut metagenome, a sheep gut metagenome, a goat gut metagenome, a capybara gut metagenome, a primate gut metagenome, a termite gut metagenome, a fecal metagenome, a genome from the Order Clostridiales, or the Family Ruminococcaceae. In an aspect, a disclosed Cast 3d ortholog can include an Cast 3d ortholog from Ruminococcus albus, Eubacterium siraeum, a Ruminococcus flavefaciens strain XPD3002, Ruminococcus flavefaciens FD-1, uncultured Eubacterium sp TS28-c4095, uncultured Ruminococcus sp., Ruminococcus bicirculans, or Ruminococcus sp CAG57.

[0120] In an aspect, a disclosed Casl3 can comprise RfxCasl3d (see, for example, US Patent Publication No. 2020 / 0244609, which is incorporated by reference for its teachings of RfxCasl3d and relevant sequences). In an aspect, a disclosed Casl3 can comprise PspCasl3b (see, for example, US Patent Publication No. 2020 / 0231975, which is incorporated by reference for its teachings of PspCasl3b and relevant sequences).As known to the art, RNA binding proteins consist of multiple repetitive sequences that contain only a few specific basic domains. Structurally, common RNA-binding domains mainly include RNA-recognition motif (RRM), K homology (KH) domain, double-stranded RBD (dsRBD), coldshock domain (CSD), arginine-glycine-glycine (RGG) motif, tyrosine-rich domain, and zinc fingers (ZnF) of the CCHC, CCCH, ZZ type etc. According to the different functions of RBPs in cells, RBPs can be divided into epithelial splicing regulatory proteins (ESRP1), cytoplasmic polyadenylation element binding protein family (CPEB1 / 2), Hu-antigen R (HuR), heterogeneous nuclear ribonucleoprotein family members (hnRNP A / D / H / K / MZE / L), insulin-like growth factor 2 mRNA family members (IMP1 / 2 / 3), zfh family of transcription factors (ZEB 1 / 2), KH-type splicing regulatory protein (KHSRP), La ribonucleoprotein domain family members (LARP 1 / 6 / 7), Lin-28 homolog proteins (Lin28), Musashi protein family (MSI1 / 2), Pumilio protein family (PUM1 / 2), Quaking (QK), RNA-binding motif protein family (4 / 10 / 38 / 47), Src- associated substrate during mitosis of 68 kDa (SAM68), serine and arginine rich splicing factor (SRSF1 / 3), T cell intracellular antigens (TIA1 / TIAR), and Upstream of N-Ras (UNR).

[0121] In an aspect, “RNA editing” can be a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid ora stop codon. This type of re-coding can significantly affect the structure and function of a protein and may lead to the production of multiple variants of a protein from a single gene.

[0122] In an aspect, insertional and deletional RNA editing can involve the addition and deletion of specific nucleotides or sequences of nucleotides from pre-mRNA. In an aspect, substitutional RNA editing by base modifications is observed in higher eukaryotes, where the base is modified without changing the length of the pre-mRNA.

[0123] In an aspect, also disclosed herein are partial self-complementary parvovirus (e.g., a disclosed AAV) genomes, plasmid vectors encoding the parvovirus genomes, and parvovirus (e.g., a disclosed AAV) particles including such genomes. In an aspect, provided herein is a plasmid vector comprising a nucleotide sequence encoding a disclosed parvovirus genome such as for example, a disclosed AAV. In an aspect, provided herein is a partial self-complementary parvovirus genome including a payload construct, parvovirus ITRs flanking the payload construct, and a self-complementary region flanking one of the ITRs. A self-complementary region can comprise a nucleotide sequence that is complementary to the payload construct. A disclosed self- complementary region can have a length that is less the entire length of the payload construct.

[0124] In an aspect, a disclosed self-complementary region of a disclosed parvovirus genome can comprise a minimum length, while still having a length that is less the entire length of the payload construct. In an aspect, a disclosed self-complementary region can comprise at least 50 bases in length, at least 100 bases in length, at least 200 in length, at least 300 bases in length, at least 400 bases in length, at least 500 bases in length, at least 600 bases in length, at least 700 bases in length, at least 800 bases in length, at least 900 bases in length, or at least 1,000 bases in length.

[0125] In an aspect, a “self-complementary parvovirus genome” can be a single stranded polynucleotide having, in the 5’ to 3’ direction, a first parvovirus ITR sequence, a heterologous sequence (e.g., payload construct comprising, for example, a desired gene), a second parvovirus ITR sequence, a second heterologous sequence, wherein the second heterologous sequence is complementary to the first heterologous sequence, and a third parvovirus ITR sequence. In contrast to a self-complementary genome, a “partial self-complementary genome” does not include three parvovirus ITRs and the second heterologous sequence that is complementary to the first heterologous sequence has a length that is less than the entire length of the first heterologous sequence (e.g., payload construct). Accordingly, a partial self-complementary genome is a single stranded polynucleotide having, in the 5’ to 3’ direction or the 3’ to 5’ direction, a first parvovirus ITR sequence, a heterologous sequence (e.g., payload construct), a second parvovirus ITR sequence, and a self-complementary region that is complementary to a portion of the heterologous sequence and has a length that is less than the entire length the heterologous sequence.

[0126] As used herein, “immune-modulating” refers to the ability of a disclosed nucleic acid molecules, a disclosed vector, a disclosed pharmaceutical formulation, or a disclosed agent to alter (modulate) one or more aspects of the immune system. The immune system functions to protect the organism from infection and from foreign antigens by cellular and humoral mechanisms involving lymphocytes, macrophages, and other antigen-presenting cells that regulate each other by means of multiple cell-cell interactions and by elaborating soluble factors, including lymphokines and antibodies, that have autocrine, paracrine, and endocrine effects on immune cells.

[0127] As used herein, the term “package insert” is used to refer to instructions customarily included in commercial packages of therapeutic products, that contain information about the indications, usage, dosage, administration, contraindications and / or warnings concerning the use of such therapeutic products.

[0128] As used herein, the term “in combination” in the context of the administration of other therapies (e.g., other agents) includes the use of more than one therapy (e.g., drug therapy). Administration “in combination with” one or more further therapeutic agents includes simultaneous (e.g., concurrent) and consecutive administration in any order. The use of the term “in combination” does not restrict the order in which therapies are administered to a subject. By way of non-limiting example, a first therapy (e.g., a disclosed nucleic acid molecule, a disclosed vector, a disclosed pharmaceutical formulation, or a combination thereof) may be administered prior to (e.g., 1 minute, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, 8 weeks, 9 weeks, 10 weeks, 11 weeks, or 12 weeks), concurrently, or after (e.g., 1 minute, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, 9 weeks, 10 weeks, 11 weeks, or 12 weeks or longer) the administration of a second therapy (e.g., agent) to a subject having or diagnosed with a disease or disorder (such as a genetic disease or disorder).

These and other materials are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these materials are disclosed that while specific reference of each various individual and collective combinations and permutation of these compounds cannot be explicitly disclosed, each is specifically contemplated and described herein.For example, if a particular compound is disclosed and discussed and a number of modifications that can be made to a number of molecules including the compounds are discussed, specifically contemplated is each and every combination and permutation of the compound and the modifications that are possible unless specifically indicated to the contrary. Thus, if a class of molecules A, B, and C are disclosed as well as a class of molecules D, E, and F and an example of a combination molecule, A-D is disclosed, then even if each is not individually recited each is individually and collectively contemplated meaning combinations, A-E, A-F, B-D, B-E, B-F, C- D, C-E, and C-F are considered disclosed. Likewise, any subset or combination of these is also disclosed. Thus, for example, the sub-group of A-E, B-F, and C-E would be considered disclosed. This concept applies to all aspects of this application including, but not limited to, steps in methods of making and using the compositions of the invention. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the methods of the invention.B. Compositions for Transcriptome Engineering (Barcoded CRAFT)

[0130] In eukaryotic organisms, chromosomal DNA is transcribed into precursor RNA messages (pre-mRNA) which contain protein coding regions (exons) and intervening non-protein coding regions (introns). Prior to processing, these pre-mRNA molecules do not possess a sequence primed for translation by the ribosome, due to the retention of non-coding intronic sequences. Thus, prior to nuclear export, the exons of pre-mRNA transcripts are joined through a cellular mechanism known as splicing. This mechanism features dual transesterifications mediated by a large multi ribonucleoprotein structure, called the spliceosome. In the first transesterification, the branch point sequence of the intervening intron attacks the 5’ splice site, forming a lariat structure. This reaction frees the 5’ splice site to attack the 3’ splice site removing the intervening intron, joining the adjacent exons. Upon removal of all intronic sequences, the precursor message matures into a translation competent mature RNA transcript, which is trafficked to the ribosome where it is decoded to manufacture cellular proteins.

[0131] In mammalian cells, mutations in transcriptionally active regions of chromosomal DNA give rise to pre-mRNA bearing identical mutations. If the mutation is located in a non-coding region, then processing of the pre-mRNA may be altered or abolished. If the mutation is located in an exonic region of the pre-mRNA, then that mutation will be passed to the mature mRNA sequence. These mutations can contribute to inhibition of complete protein translation of the encoded protein (non-sense mutation) or modify the primary structure of the encoded protein in a counter-productive manner (missense mutation). Collectively, these genetically encoded mutations may function to contribute to pathogenesis in eukaryotes.1. Nucleic Acid Molecules5’ Replacement Constructs

During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifuss muscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie- Tooth disease, and Hutchinson-Gilford progeria syndrome.

Channel activation is mediated by cycles of regulatory domain phosphorylation, ATP -binding by the nucleotide-binding domains, and ATP hydrolysis. Mutations in this gene cause cystic fibrosis, the most common lethal genetic disorder in populations of Northern European descent. The most frequently occurring mutation in cystic fibrosis, DeltaF508, results in impaired folding and trafficking of the encoded protein.

The nuclear lamina consists of a two-dimensional matrix of proteins located next to the inner nuclear membrane. The lamin family of proteins make up the matrix and are highly conserved in evolution. During mitosis, the lamina matrix is reversibly disassembled as the lamin proteins are phosphorylated. Lamin proteins are involved in nuclear stability, chromatin structure and gene expression. Vertebrate lamins consist of two types, A and B. Alternative splicing results in multiple transcript variants. Mutations in this gene lead to several diseases: Emery-Dreifussmuscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie-Tooth disease, and Hutchinson-Gilford progeria syndrome.

Expansion of this unstable motif to 50-5,000 copies causes myotonic dystrophy type I, which increases in severity with increasing repeat element copy number. Repeat expansion is associated with condensation of local chromatin structure that disrupts the expression of genes in this region. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.
