A hereditary osteochondrodysplasia affecting the wrist and forearm, including the distal RADIUS; ULNA; and proximal CARPAL BONES. It commonly occurs in Leri-Weill dyschondrosteosis (OMIM: 127300), which is associated with mutations in the SHOX gene located on the pseudoautosomal region of the X and Y chrosomosmes; thus, inheritance is autosomal dominant.
