The results of assessing the sufficiency offolic acid of the residents of the Moscow region have been presented depending on rs1801133 MTHFRgene polymorphism and rs9939609 FTO gene polymorphism. A total of 326 people were examined, including 74 men and 252 women aged 20 to 65 years. The results of determining the level of folic acid in blood serum showed insufficiency of this vitamin among the population of the Moscow region of the Russian Federation. The expressed vitamin deficit (level <3,0 ng/ml) was detected in 24.2% of the surveyed residents, in 22.8% folic acid level was at the lower bound of the norm (3.0-4.5 ng/ml). The results of genotyping showed a statistically significant association of low folic acid level with rs1801133 MTHFR gene polymorphism in carriers of A allele of rs9939609 FTO gene polymorphism both in the homozygous state (genotype AA) and in the heterozygous (genotype AT) state, OR=4.26; CI (1.40-12.9), p=0.008, as well as with rs9939609 FTO gene polymorphism in carriers of the T allele of rs1801133 MTHFR gene polymorphism both in the homozygous (genotype TT) and heterozygous (CTgenotype) state, OR-3.29; CI (1.07-10.1), p=0.03. In carriers of 3 alleles of risk offolic acid deficiency [rs9939609 FTO gene polymorphism and rs1801133 MTHFR gene polymorphism (genotypes CT/AA and TT/AT)] blood serum level of folic acid was below the norm, that indicated folate deficiency in this category of persons.
