Description
Technical Field
The invention relates to the field of SNP typing detection in the technical field of genetic engineering, in particular to a kit for specifically detecting sarcopenia by detecting rs 112892337.
Background
Sarcopenia, also called Sarcopenia (Sarcopenia), is a chronic metabolic disease of the elderly, which is mainly characterized by the decrease of the quality of skeletal muscle fibers, the decrease of muscle strength, the decrease of muscle endurance and metabolic capability, the increase of connective tissues and fat, and the like with the increase of age. Sarcopenia often causes the mobility of the old to be reduced, daily actions such as walking, sitting, climbing, lifting heavy objects and the like are influenced, and the hand is gradually free from binding the force of chicken. The muscle function is reduced, and the probability of accidental falling injury of the old is increased by 40 percent. Statistically, 50% of the elderly die from accidents due to falls. The risk of inconvenient actions of the sarcopenia old people is 2-5 times that of the old people of the same age, and the life quality and the self-care ability of the old people are seriously influenced.
Sarcopenia not only increases the risk of disability and loss of self-care ability of life, but also promotes the development of diseases such as osteoporosis and arthritis, and is also an important reason for inducing senile diseases such as hypertension, diabetes and hyperlipidemia. Sarcopenia has become one of the leading causes of disability and death worldwide. Sarcopenia occurs in 13-24% of the elderly under age 70, with a prevalence of up to 50% and even higher in those over age 80. Annual economic losses associated with sarcopenia exceed $ 1000 billion.
Numerous studies of candidate genes in the past have shown that many genes are associated with changes in human muscle mass. More than 40% of the genetic variations associated with the human lean body mass index (LMI) can produce differences in traits. With the progress of molecular genetics, it is found that sarcopenia is a polygenic genetic disease, and genetic association research of sarcopenia is carried out in many countries. At least 20 human genes or chromosomal regions have been detected by molecular genetics and reported to be associated with sarcopenia to date. In addition, both genetic and molecular epidemiological evidence suggests that genetic factors are involved in determining susceptibility to increased or lost muscle mass in specific dietary or drug regimes, as well as a high risk of developing other related diseases in sarcopenia patients. At present, many candidate genes exist, but most of the candidate genes are required to be further improved in detection accuracy.
As for the method for detecting sarcopenia genes, the conventional detection method at present includes Restriction Fragment Length Polymorphism (RFLP), which is a method for simply treating the PCR product of a patient by enzyme digestion and then detecting whether there is variation when the variation affects the enzyme cutting site of a certain Restriction enzyme. However, the method has the defects of long time consumption, complex operation, low accuracy and the like. The detection of gene polymorphism sites by PCR combined with DNA sequencing is also useful, but the application of this method in large-scale population screening or detection of multiple sites of multiple genes is limited. Therefore, it is necessary to establish a high-throughput, high-efficiency and low-cost SNP (single nucleotide polymorphism) typing method for sarcopenia susceptibility genes to realize clinical rapid detection or large-scale population screening.

Detailed Description
EXAMPLE 1 obtaining molecular markers for SNPs
1, sample of
The samples used in the present invention were from a uk biosample bank (UKB) cohort of samples. The cohort was a large prospective study cohort containing 50 million participants between 48-73 years of age from all over the country in the uk. We use a series of strict nanocriterions. Inclusion criteria included analysis of only participants reported as "whites". Exclusion criteria included inconsistency of self-reported sex with genetic sex, non-ploidy sex chromosomes, too high a heterozygosity, too high a genotype deletion rate, and the like. There were 48.7 million participants, and 450243 participants remained available for analysis after the exclusion of 3.7 million participants, of which 205513 were male and 244730 were female.
2, phenotype and modeling thereof
Body composition including muscle content and fat content was measured using a bioelectrical impedance method. The fat content and the muscle content of the arms and the legs are measured in sequence, and the muscle content of the limbs is obtained by adding the muscle content of the arms and the legs. Male and female are modeled separately. In each sex, the raw limb muscle mass was corrected using the limb fat mass, age square, first ten genetic principal components, the measurement location, and the chip used for genotyping as covariates. The corrected residuals were converted to standard normal distributions according to the inverse quantile method and used for downstream analysis.
3, genotype and quality control thereof
All participants were typed using a custom UKB genotyping chip, and genotypic information for 784256 Single Nucleotide Polymorphic Sites (SNPs) was obtained by genotyping on the autosome in total. Statistical methods of genotype filling were used to fill in large genomic reference panels. The panel consisted of the UK10K haplotype, the thousand genome 3-phase data, and the haplotype reference sample. Approximately nine thousand two million SNPs were co-complemented. As a nano-exclusion criterion, SNPs with a sub-allele frequency <0.1% and a filling precision <0.3 were excluded. After quality control, there were a total of nineteen million SNPs for downstream analysis.
4, genetic Association analysis
Within each gender group, genetic association analysis of the mixed linear model was performed using the BOLT-LMM software. After the correlation analysis of both sexes was completed, meta analysis was performed on the genetic correlation signals of both sexes using the inverse variance weighted fixed effect model of METAL software. The whole genome significance level was set at α =5 × 10-9. The SNP sites achieving this significance level also meet the gender-specific significance level of α =5 × 10-5. That is, significant correlation signals not only meta-analyzed p-values<5×10-9Simultaneous p-values in both gender groups<5×10-5。
The magnitude of the effect of SNPs in the two sex panel was compared using the two-sided z-test. The identified SNP sites were annotated using the Variant Effect Predictor (VEP) software.
5, age Effect
As a typical geriatric disease, the genetic effects of sarcopenia may change with increasing age. Therefore, the patent also evaluates the trend of the SNP effect with age. The specific method is to divide UKB samples into 6 age groups: under age 45 (N =54608), 46-50 (N = 58865), 51-55 (N = 70253), 56-60 (N = 89479), 61-65 (N = 109696), and above age 66 (N = 67342). Genetic association analysis was performed using BOLT-LMM software within each age group. The generated regression coefficients were subjected to meta regression analysis for the average age of each group. The P value of the regression analysis was used as a criterion for the significance.
6, conclusion
SNP site rs112892337 was identified in the UKB sample. Its effect value in the male sample was 0.16, the effect value in the female sample was 0.13 and the overall effect value was 0.14. The effect values did not differ in the male and female groups. The three genotypes CC, GG and CG of rs112892337 correspond to limb muscle content of on average 24.3 kg, 21.7 kg and 19.2 kg, respectively, corresponding to a reduction of about 2.5 kg per allele G. Its main genetic association results are shown in table 1.
TABLE 1 genetic Association results for rs112892337
Note: c in allele C/G is the contributing allele.
The site is a missense mutation and is located on chromosome 8ZFATOn the 7 th exon of the gene. The mutation results in the mutation of amino acid 470 of the encoded protein from serine to cysteine. Bioinformatic analysis showed that the mutation had a severe disruptive effect on protein function.
To further determine whether the genetic effect of rs112892337 changes with age, the patent also performed age-specific analyses. No age-specific effect was found as a result of the analysis.
Taken together, the two allelic positions C and G of the missense mutation rs112892337 are able to distinguish well between high and low muscle groups. When the allele is G, it shows sarcopenia property, and when it is C, it does not show sarcopenia property. Allelic form GG results in a reduction in muscle content that ultimately leads to the development of sarcopenia, which is statistically extremely significant and thus can be detected by detecting this locus genotype.
The above description of the embodiments is only intended to illustrate the method of the invention and its core idea. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications will also fall into the protection scope of the claims of the present invention.
