Abstract

Several studies have investigated the link between two different polymorphisms (C677T and A1298T) of the gene encoding methylenetetrahydrofolate reductase (MTHFR) and the risk of recurrent pregnancy loss (RPL); however, the results remain controversial. This study aimed to provide greater insight into this debated topic. In the current study, two groups of pregnant women (group A: RPL women; group B: non‑RPL women), each of which were subdivided further into two subgroups based on their gestational age, were screened for C677T and A1298T variants of the MTHFR gene. The resulting data were analyzed using receiver operating characteristic (ROC) curve and Z test methods to compare the two groups. These ROC curve and Z test analyses indicated that there were no differences between the groups regarding C677T and A1298T expression. RPL is primarily caused by mutations in prothrombin or factor V Leiden genes. However, a low percentage of RPL cannot be attributed to these mutations. In the last five years, research has focused on the MTHFR gene, the two major variants of which (C677T and A1298T) have been associated with an increased risk of cardiovascular diseases (thrombotic events) in homozygous individuals. In addition, these mutations may be related to an increased rate of neural tube defects in fetuses. While a link between MTHFR mutation and RPL may be expected based on previous findings, the present study indicated the absence of an association between the polymorphisms of the MTHFR gene and RPL risk.
