Abstract
Background: The aim of the study is to investigate the relationship between Methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR) polymorphisms, 5 serum related molecular levels and the risk of adverse pregnancies in different genders.
Methods: Patients aged from 22 to 38 with a history of adverse pregnancy treated in our genetic eugenics clinic of Henan Provincial People's Hospital are selected. The controls aged from 20 to 34 undergoing eugenics examinations in our genetic eugenics clinic that had no history of adverse pregnancy and at least one healthy child are selected. Sanger sequencing and Chemiluminescence Microparticle Immuno Assay (CMIA) are used for detecting the mutations of MTHFR and MTRR and the 5 serum molecular serum levels.
Results: In the female group, MTHFR 677 C > T is associated with Recurrent spontaneous abortion (RSA) (P = 0.0017), Chromosomal abnormality (CA) (P = 0.0053), Cleft lip and palate (CLP) (P = 0.0326) and Brain dysplasia (BD) (P = 0.0072); MTHFR 1298 A > C is associated with Infertility (P = 0.0026) and BD (P = 0.0382); MTRR 66 A > G is associated with CLP (P = 0.0131). In the male group, MTHFR 677 C > T is associated with RSA (P = 0.0003), Infertility (P = 0.0013), CA (P = 0.0027) and BD (P = 0.0293). In the female group, the genotype of MTHFR 677 C > T is associated with RSA (P = 0.0017), CA (P = 0.0014) and BD (P = 0.0021); MTHFR 1298 A > C is associated with Infertility (P = 0.0081) and MTRR 66 A > G is associated with Infertility (P = 0.0309). In the male group, the genotype of MTHFR 677 C > T is associated with RSA (P = 0.0008), Infertility (P = 0.0096) and CA (P = 0.0165) and MTRR 66 A > G is associated with Infertility (P = 0.0158) and congenital heart disease (CHD) (P = 0.0218). In the male group, there is statistically significant difference of the serum Homocysteine (Hcy) levels (P < 0.0001) between adverse pregnancy group and controls. In the female group, there is statistically significant difference of the serum vitamin D levels (P = 0.0015) between adverse pregnancy group and controls.
Conclusions: Polymorphic variants in MTHFR and MTRR, serum Folic acid (FA), Hcy and B12 levels in the male group and vitamin D levels in the female group are associated differentially with adverse pregnancy.
