A rare syndromic intellectual disability characterized by intellectual deficit, short stature, obesity, genital abnormalities, and hand and/or toe contractures. The patients also present with generalized osteoporosis and a history of frequent fractures. This syndrome is similar to Prader-Willi syndrome, but the hand contractures and osteoporosis, together with the lack of hypotonia, indicate this is a different entity.
