DACH1 and Hip dysplasia: Previously described genes DACH1, MYH10, NOTCH2, TBX4, EVC2, OTOG, and SHC3 have highly damaging variants also in our study group; of these TBX4, EVC2, NWD1, and OTOG have variants in more than one family further strengthening the notion that they are involved in the etiopathogenesis of DDH.
