Correlation Between Long non-coding RNA SOX2OT rs9839776 C>T Polymorphism and Unexplained Recurrent Miscarriages

Recurrent miscarriage (RM) is a severe pregnancy complication that results in the loss of two or more spontaneous pregnancies. RM has several complex reasons. Advances in genetics, immunology, and cell biology have strongly connected non-coding RNAs (ncRNAs) to recurrent miscarriages. NcRNAs regulate placental trophoblast cell processes, which affect trophoblast development, migration, and invagination; they also have a role in breast and ovarian cancer. As a result, their abnormal expression may contribute to the progression of RM. Several investigations have found a connection between RM and genetic polymorphisms that regulate cell migration. Variations in the long non-coding RNA (lncRNA) SOX2OT gene have been associated with a variety of cancer-related illnesses, particularly colorectal cancer, breast cancer, and cancer of the digestive tract. According to a recent study, the long non-coding SOX2OT rs9839776 CT raises the risk of RM. In this review, we explain the existing evidence supporting a relationship between the LncRNA SOX2OT rs9839776 polymorphisms and recurrent miscarriages.
