27, 28 However, it remains unclear whether the TOX3 gene is also associated with recurrent abortion susceptibility, similar to lncRNA CCAT2. These previous studies suggest that genetic variation in the TOX3 locus may be associated with susceptibility to RM. However, there is currently no study on the relationship between the TOX3 rs3803662 C>T polymorphism and the risk of RM. These findings prompted us to evaluate whether the rs3803622 variant of the TOX3 gene is associated with RM susceptibility and whether rs3803622 C>T can be used as a biomedical indicator or a potential risk factor. Here, TOX3 is linked to abortion.
