Abstract

AbstractSeveral maternal genetic variations are known to play an important role during pregnancy since they can affect mother health and/or fetal growth. The frequency of these variants is variable among different populations. This study aimed to investigate thrombophilia, folate metabolism and hypertension genetic variants in reproductive age women of Rostov region (Russia) and then assess their linkage disequilibrium (LD) and heterogeneity among populations. A total of 3108 reproductive age women were included (33.75 ± 5.13 years). Twenty‐one genetic variants were detected with RT‐PCR. LD was tested according to (D′) coefficient and p value. The highest frequency of mutant allele in studied population was as follows: PAI‐1 rs1799768, MTRR rs1801394, AGT rs699, and AGTR2 rs1403543. We showed a high possibility of coinheritance of MTHFR rs1801133 with rs1801131 and AGT rs699 with rs4762 (D′=0.992 and 0.999, respectively). In addition, comparative analysis showed F7 rs6046, FGB rs1800790, MTR rs1805087, and AGT rs699 significantly more frequent among Rostov females by 1.3–1.5 times than European. MTHFR rs1801133, ADD1 rs4961, AGTR2 rs1403543, NOS3 rs2070744, and rs1799983 were with higher frequencies in Europeans than those in the studied group. Our data could be used as a reference for further associative studies of targeted genetic variations in different pregnancy complications specifically in this population.
