GLI3 and postaxial polydactyly type A: Mutations affecting GLI3 are responsible of different syndromic conditions, including the Greig cephalopolysyndactyly syndrome (OMIM 175700), the Pallister–Hall syndrome (OMIM 146510) and the Postaxial polydactyly type-A (OMIM 174200), but none of such conditions are associated with WT development.
