Pathogenic mutations in ROR2 are involved in two diseases: autosomal recessive Robinow syndrome (RRS, MIM:268310) and autosomal dominant brachydactyly type B1 (BDB1, MIM:113000) (Afzal et al., 2000; Yang et al., 2020; Zhang et al., 2020). Here, ROR2 is linked to autosomal recessive Robinow syndrome.
