Effect of steroid hormone receptor gene variants PROGINS (Alu insertion) and PGR C/T (rs1042839) as a risk factor for recurrent pregnancy loss in Kashmiri population (North India).

Aim: To unveil and evaluate the association and analyze the incidence and pattern of PGR gene polymorphisms (PROGINS insertion and PGR exon 5-C/T polymorphism) in recurrent pregnancy loss (RPL) couples of Kashmir.

Methods: In this study, analyses of PGR gene polymorphisms in RPL couples were genotyped by amplification-refractory mutation system polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism.

Results: Molecular analysis of PGR gene polymorphisms indicated that the genotypic and allelic frequencies of PROGINS insertion and PGR exon 5 C/T polymorphisms of female group in cases and controls to be significantly different and poses risk in predisposition to RPL.
