The present study included the genetic variants for the GDM risk, such as PPMIK, FGF2, AHR, PRKAG2, PTPRD, PPP1R12A, and PTPRM, which were mostly involved in insulin sensitivity, but did not show high statistical significance with the T2DM risk in previous studies [10,12]. Here, INS is linked to type 2 diabetes mellitus.
