In addition, with this study we are adding 22 new candidate genes to the list of genes to consider in DSD (CDH23, COL9A3, CYP1A1, DAPK1, EMX2, EYA1, FGF10, GLI2, GRID1, IGFBP2, IRX6, MAML1, MAML2, MAML3, MYO7A, NOTCH1, NRP1, PIK3R3, PPARGC1B, TGFBI, WNT9A, and WNT9B). Here, IGFBP2 is linked to disorder of sexual differentiation.
