A syndromal osteochondrodysplasia due to a contiguous gene deletion syndrome. The characteristics of this syndrome are progressive bowing of forearms and forelegs leading to mesomelia, progressive intracarpal or intratarsal bone fusion and fusion of metacarpal bones with proximal phalanges, ptosis, hypertelorism, abnormal soft palate, congenital heart defect and ureteral anomalies. To date 5 unrelated patients have been reported, including one family with multiple affected persons. This syndrome is due to a non-recurrent microdeletion in 8q13. All patients have a deletion of two contiguous genes: SULF1 and SLCO5A1. Transmitted as an autosomal dominant trait.
