Problems solved by technology

However, PCR-RFLP involves enzyme digestion, and the traditional experimental design without internal control enzyme digestion sites will hardly avoid misjudgment of results in the case of incomplete enzyme digestion

Embodiment 1

[0090] In this example, 3 pairs of primers for detecting the genotype of the CYP2C19*3 polymorphic site were designed for the restriction endonuclease HinfI, and a detection method for the genotype of the CYP2C19*3 polymorphic site was established, as follows:

[0091] 1. Genomic DNA extraction

[0092] Using oral swab genomic DNA extraction kit or blood genomic DNA extraction kit, extract genomic DNA according to the operation steps in the manual. The DNA source is not limited thereto, and any somatic cell-derived DNA is acceptable.

[0093] 2. Primer design

[0094] Get the 1000bp sequence before and after the CYP2C19*3 polymorphic site, analyze its homology with other genes of the CYP2C subfamily, namely CYP2C9, CYP2C18, and CYP2C8, and use Primer Premier 5.0 software to design specific typing for this site primers. Among them, the internal control enzyme cutting site is GATTC upstream of the polymorphic site or GAGTC downstream of the polymorphic site, see image 3 , ...

Embodiment 2

[0144] This embodiment is aimed at the restriction endonucleases EcoRI, MvaI [the isozymes include AjnI, BseBI, Bst2UI, BstNI, BstOI, Psp6I, PspGI, EcoR II, BciT130I, etc.], Bme1390I [the isozymes include ScrFI, BmrFI, BssKI, BstSCI, MspR9I, StyD4I, etc.], BseDI [isozymes include BsaJI, BssECI, etc.] designed a pair of primers for detecting the CYP2C19*3 polymorphic site genotype, and established the CYP2C19*3 polymorphic site genotype The detection method is as follows:

[0145] 1. Genomic DNA extraction

[0146] Using oral swab genomic DNA extraction kit or blood genomic DNA extraction kit, extract genomic DNA according to the operation steps in the manual. The DNA source is not limited thereto, and any somatic cell-derived DNA is acceptable.

[0147] 2. Primer design

[0148] Get the 1000bp sequence before and after the CYP2C19*3 polymorphic site, analyze its homology with other genes of the CYP2C subfamily, namely CYP2C9, CYP2C18, and CYP2C8, and use Primer Premier 5.0 ...

Abstract

The invention discloses a method for detecting a CYP2C19*3 polymorphic site genetype and a kit. The method comprises the steps of introducing a specific 'inner quality control' mechanism during a process of detecting the CYP2C19*3 polymorphic site genetype, i.e. introducing an internal control restriction enzyme cutting site in a PCR (Polymerase Chain Reaction) product, identifying a situation of incomplete enzyme cutting according to a macrorestriction map, and still accurately judging the genetype under the situation of incomplete enzyme cutting, so that the accuracy of a detection result is greatly improved.

Description

technical field [0001] The invention belongs to the field of molecular detection, and in particular relates to a method and a kit for detecting the genotype of a CYP2C19*3 polymorphic site. Background technique [0002] CYP2C19 is an important member of the cytochrome P450 (CytochromeP450, CYP) enzyme system and an important drug metabolizing enzyme in the body. It was first isolated from human liver by Wrighton et al. in 1993. The full length of its cDNA is 1940bp, and the coding region is 1473bp , encoding 490 amino acid residues. CYP2C19 participates in a wide range of drug metabolism, including proton pump inhibitors (omeprazole, lansoprazole, pantoprazole), antidepressants (fluoxetine, citalopram, escitalopram, albino Mitriptyline, clomipramine, imipramine, moclobemide, trimipramine, etizolam), antiepileptic drugs (valium, clobazam, phenytoin, phenobarbital, valproic acid ), platelet aggregation inhibitors (clopidogrel), antimalarials (proguanil), antifungals (voricon...
