Description

Technical Field

[0001] The present invention relates to the field of molecular diagnostic technology, and in particular to the use of a reagent for detecting 32 gene mutations in the preparation of physical fitness testing products. Background Art

[0002] Fitness-related gene testing is an innovative genetic testing technology based on a time-of-flight nucleic acid mass spectrometry platform. By collecting oral mucosal samples from the subjects and performing nucleic acid mass spectrometry analysis on the DNA in the samples, it can be determined whether the subjects have sports-related gene mutations, understand personal sports talents, and provide a testing basis for formulating exercise plans and training intensity.

[0003] Sports practice shows that the quality of a person's athletic genetics determines the upper limit of their athletic ability and the degree of their trainability. The most fundamental reason for this is that different individuals have different genetic backgrounds, that is, there are differences in athletic talent.

[0004] 1. Differences in traits are determined by innate genetics. Human biological traits are controlled both by genetics and by the environment. An athlete's response to training stimuli is largely determined by heritability. Traits with high heritability, such as endurance, maximum oxygen uptake, and the ratio of red to white muscle fibers, are difficult to improve through training.

[0005] Second, differences in traits determine athletic ability. Research shows that favorable physical traits are essential for achieving outstanding athletic ability and determine the potential for athletic development. Recent molecular genetic research has repeatedly confirmed that traits related to human athletic ability, such as muscle strength, endurance, balance, coordination, flexibility, aerobic capacity, anaerobic capacity, training response, and the development and progression of fatigue, all have a significant biological basis. Given similar environmental conditions and training methods, individuals can exhibit significant differences in athletic ability, physical fitness, comprehension, and training response. Therefore, favorable physical traits are essential for achieving excellence in certain sports. Genetic testing for physical fitness can provide essential information for athletes to develop exercise plans and training intensity, maximizing training efficiency while maintaining physical fitness, enabling more scientific and rational training plans and achieving better results. Naturally, genetic testing for physical fitness is also suitable for students and those seeking to specialize in a particular sport, providing a comprehensive understanding of their athletic abilities and providing scientific advice when choosing a sport.

[0006] The basic principle of matrix-assisted laser desorption / ionization time-of-flight mass spectrometry (MALDI-TOF MS) is to disperse the analyte within matrix molecules, forming crystals. When the crystals are irradiated with laser light, the energy absorbed by the matrix molecules accumulates and rapidly generates heat, causing the matrix crystals to sublime, expanding the matrix and analyte into the gas phase. The mass spectra produced by MALDI are mostly singly charged ions, corresponding to the masses of peptides and proteins, and molecular weights are calculated based on the mass / charge ratio. MALDI-generated ions are often detected using a time-of-flight (TOF) detector. The ions are then analyzed based on their mass-to-charge ratio (M / Z), which is proportional to their time of flight, and the molecular weight of the sample molecules is determined. MALDI-TOF mass spectrometry is well-suited for the study of biomacromolecules such as proteins, peptides, polysaccharides, and nucleic acids. Because of its advantages such as wide mass determination range, high sensitivity, fast speed, high accuracy and good tolerance to salt, it has been widely used in the molecular weight and sequence determination of proteins and peptides.

[0007] The present invention's MALDI-TOF mass spectrometry detection of fitness-related gene loci presents difficulties: the design of amplification primers (i.e., multiplex PCR primers) for each detection locus, as well as the design of extension primers, the ratio of each primer during composite amplification, and the optimal concentration of each component in the system all need to be optimized to ultimately achieve intra-site, intra-group, and inter-group balance and stability that meet practical application requirements. Some loci have special sequence structures or high GC content, making it difficult to design primers for multiplex PCR. Summary of the Invention

The specific detection sites are as follows: rs12722, rs10887741, rs1815739, rs2253206, rs11549465, rs1042713, rs3764352, rs12612420, rs6265, rs2073711, rs1800795, rs363050, rs800562, rs699, rs1842129, rs12143842, rs2016520, rs4665058, rs679620, rs1799945, rs363039, rs4783307, rs2267668, rs4994, rs591058, rs1799722, rs8097348, rs1800012, rs8192678, rs4948418, rs1208, rs17602729, and then designed upstream and downstream amplification primers for the detection sites, which were synthesized by Shanghai Biolige Biotechnology Co., Ltd.

[0033] Example 2: Optimization and Improvement of Pretreatment Reagents for Fitness-Related Gene Detection and Analysis (1) Optimization of UNG Enzyme Concentration

[0034] Prepare the PCR reaction mixture according to the table below and divide it into four groups, adding 0.5, 0.25, 0.125, and 0.05 μl / person of UNG enzyme to each group, respectively. Wild-type and mutant samples were diluted to 50 ng / μl, 20 ng / μl, 10 ng / μl, 5 ng / μl, 1 ng / μl, and 0.5 ng / μl, respectively, and 1 μl / person of each was added to the reaction system. PCR reactions were performed using 0.5 ng / μl of whole blood genomic DNA as a template according to the PCR reaction system and protocol in Tables 3 and 4. After the PCR reaction, the PCR products were digested with SAP according to the SAP system and protocol in Tables 5 and 6. The digested products were then extended according to the extension system and protocol in Tables 7 and 8. After the extension reaction, 18.5 μL of ultrapure water was added to the extension products, mixed thoroughly, and transferred to a 384-well plate for mass spectrometry detection using a DP-TOF time-of-flight mass spectrometer.

[0051]

[0052] Note: √ indicates that the sample interferes with the normal reading of genomic DNA, and × indicates that the sample does not interfere with the normal reading of genomic DNA; + indicates that all sites of genomic DNA can be read normally, and - indicates that there are sites in genomic DNA that cannot be read.

[0053] The results showed that the addition of 0.25 μL / person and 0.5 μL / person UNG enzyme incubation may affect the normal detection of genomic DNA, and the addition of 0.05 μL / person UNG enzyme could not eliminate 10 4 Contamination of samples with a concentration of 10 copies / μL or higher. Using 0.125 μL / sample of UNG enzyme provides good decontamination capabilities without affecting the normal amplification of template DNA. Therefore, 0.125 μL / sample is the appropriate amount of UNG enzyme added for this reaction system.

[0054] (2) Optimization of dUTP dosage

[0055] According to the appropriate addition amount of UNG enzyme obtained in 9, 0.125 μL, the appropriate addition amount of dUTP in the system was optimized so that the UNG-dUTP could reduce exogenous contamination with the greatest efficiency and would not affect the sensitivity of the nucleic acid mass spectrometry detection method.

[0056] Sample: Whole blood sample provided by Hangzhou Dian Medical Testing Center Co., Ltd. After nucleic acid extraction, the concentration was diluted to 40 ng / μl.

[0057] method: Prepare the PCR reaction solution according to the system in Table 10 and divide it into 3 groups. Add 0.01, 0.025, and 0.05 μl / person of dUTP to each group respectively. Take the negative sample mother solution and the positive sample mother solution and dilute them to 10 2 1 μl of each sample (100 copies / μl) and 40 ng / μl of nucleic acid sample DNA were added to the reaction system. Three replicates were performed for each dUTP concentration. PCR reactions were then performed according to the protocol in Table 4. After the PCR reaction, the PCR products were digested with SAP using the SAP system and protocol in Tables 5 and 6. The digested products were then extended using the extension system and protocol in Tables 7 and 8. After the extension reaction, 18.5 μL of ultrapure water was added to the extended products, mixed thoroughly, and transferred to a 384-well plate for mass spectrometry detection using a DP-TOF time-of-flight mass spectrometer.

[0063] Note: + indicates that all sites can be detected and read normally, - indicates that some sites cannot be detected or read normally

[0064] The results showed that when the dUTP dosage was 0.01 μl / person, the exogenous interference samples added could not be completely removed from the normal detection samples, affecting the reading of the correct sample results; when the dUTP dosage was 0.05 μl / person, the amplification of some sites in the sample to be tested was affected, and there was a risk of not being able to obtain completely correct results for all sites. Therefore, the appropriate dUTP dosage for this study was 0.025 μl / person.

[0129] Conclusion: The results of Sanger sequencing were completely consistent with those of nucleic acid mass spectrometry.

[0130] Advantages of this method: All 32 sites can be detected in one well reaction, while the sequencing method requires 32 well reactions, and the workload and cost are much higher than this method.

[0131] Example 6: Testing the sensitivity of fitness gene loci using the kit of the present invention

[0132] In this example, three DNA samples were selected and serially diluted. The starting DNA loading amounts were 10 ng, 5 ng, 2.5 ng, 1 ng, 0.5 ng, 0.2 ng, and 0.1 ng, respectively. Subsequent PCR, digestion, extension, and on-machine testing were performed. The statistical results of the three samples are shown in Tables 22 to 24:

[0137]

[0138]

[0139] Table 24. Sensitivity test results of sample 3

[0140]

[0141] The results showed that all loci in the three samples were correctly detected with a sample load as low as 0.2 ng, while some loci were not detected with a sample load of 0.1 ng. This indicates that the kit can detect all 32 loci simultaneously with as little as 0.2 ng of genomic DNA, demonstrating its high sensitivity and suitability for research on complex or rare samples.

[0142] Example 7: Generating a physical fitness report using the kit of the present invention to detect physical fitness gene loci

[0143] The detection site of the present invention was used for detection, and the detection results are shown in Table 25.

[0144]

[0145] Based on the Chinese population GWAS research and database, and calculated using the PRS model, we obtained physical fitness data from the test results and generated a physical fitness report, which included the following items:

[0146]

[0147] The test results were compared with traditional physical fitness tests and were consistent, thus indicating that the detection site of the present invention can be used for physical fitness prediction.
