Association between polymorphism of has-miR-125 (rs12976445) and susceptibility to idiopathic recurrent pregnancy loss in Iranian women

Introduction: Many new studies related to peri-implantation period and maintenance of pregnancy suggest that microRNAs have fundamentally role in regulating critical pathways in early pregnancy loss and implantation failure. This study was performed with aim to evaluate the possible association between has-miR-125 T>C polymorphism and susceptibility to idiopathic recurrent pregnancy loss (RPL). Methods: In this case-control study, 116 females with at least two or more recurrent pregnancy loss and 89 healthy women with a history of two successful pregnancies and without a history of miscarriage were evaluated. DNA molecule was extracted by RGDE method and genotyping was performed by ARMS Tetra method. Data were analyzed by SPSS software (version 22) and Chi-squared test. P
