Association of FSHR missense mutations with female infertility, in silico investigation of their molecular significance and exploration of possible treatments using virtual screening and molecular dynamics.

This study investigated the association of A419T (rs121909661) and T449I (rs28928870) with infertility among Iranian women and possible treatments by agonizing the mutated receptor. 151 women were genotyped at A419T and T449I sites. Homology modeling, pharmacophore modeling, virtual screening, docking and molecular dynamics (MD) were performed. A419T and T449I indicated a significant and a weak association with infertility among Iranian women (P = 0.005 and P = 0.03, respectively). Significant differences found among three genotypes of A419T with FSH (P = 0.01) and LH (P < 0.0001). G-allele carriers of A419T had susceptibility to display higher FSH and LH serum levels. In silico results revealed the most potent agonists among 3041 similar compounds and MD supported this finding. Altogether, genotyping of A419T and T449I as potential markers might be helpful in prognosis and treatment of infertility. Also, a new series of potent FSHR agonists were identified for future drug development and treatment of infertility related to FSHR dysfunction.
