*Count of homozygotes for the minor allele/heterozygotes/homozygotes for the frequent allele. Logistic regression model was used. CHR: Chromosome, SNP: Single nucleotide polymorphism, FGR: Fetal growth restriction, H0: Observed heterozygosity, Hе: Expected heterozygosity, MTR: 5,10-methylenetetrahydrofolate reductase, MTRR: Methionine synthase reductase, SHMT1: Serine hydroxymethyl transferase 1, TYMS: Thymidylate synthetase. PHWE: Significance level for correspondence to the Hardy-Weinberg equilibrium (Chi-square test was used). Here, TYMS is linked to fetal growth restriction.
