A comparative analysis of allele frequencies of rs1801133 and rs1801131 of MTHFR in patients with stroke and healthy people from the Moscow region

Introduction. The design of studies aimed at finding the association between the genetic factor and the studied feature (disease) involves a comparison of the ratio of genotypes or allelic proportions in the study group with those in the control group. At the stage of determining the ratio of genotypes of the studied polymorphisms in the reference group, researchers meet a number of problems, which are the subject of the present work. Aim of the work is to provide scientific rationale for the feasibility of creating a national information system comprising genetic data of the relatively healthy population of Russia, incorporating its ethnic diversity. Materials and methods. The study group, total 1020 people, was genotyped for a number of single nucleotide polymorphisms of human genes. A comparative characteristic of the frequency distribution of the studied polymorphisms with those presented in international databases as reference data was carried out using χ2 index. Results. The frequency of SNP rs4986790 of the TLR4 gene significantly differs from the EUR population (p = 0.032) and the CEU subpopulation (p = 0.047). The allele frequencies of the rs1800795 (IL6) and rs1800896 (IL10) polymorphisms in the study population differ from the CEU subgroup (p = 0.030 and 0.012, respectively). The frequency of SNP rs2295119 (HLA-DPA2) in the study group is significantly different from the EUR population (p = 0.034). Conclusion. The analysis carried out in this work confirms the need to create a domestic information system containing data on the occurrence of SNP alleles and genotypes for a conditionally healthy population and in subgroups with various pathological conditions.
