Abstract

Recurrent miscarriage is a loss of disconcerting disorder characterized by RPL (recurrent pregnancy loss) of pregnancy, affecting around 1-2% of couples trying to conceive. Exposure to pesticide affects spontaneous abortion, and infertility in women. Placental oxidative stress is often linked to miscarriage. Therefore, it is of interest to link PON1 (Q1922R) polymorphism with recurrent pregnancy loss. We selected 200 subjects in which 100 patients with RPL having consecutive 2 or more miscarriages and 100 healthy controls from the northern India for this study. Blood samples were collected for DNA isolation and further assessment. Genotyping of the Q1922R polymorphism was completed using the RFLP markers. The digested PCR product size was 99 bp (control). The heterozygous fragments were found to be 66 and 33 bp homozygous mutants. It was observed that allele frequency homozygous (TT) was more prevalent among control than the case groups among the healthy north-Indian population. However, heterozygous group (Tt) was more in cases compared to control groups as well as homozygous mutant was observed high in control in than case (CI-0.3 to 1.3).
