Abnormalities of the fingers and toes have also been reported. These may include webbing or fusion of the fingers and toes (syndactyly). The severity of the syndactyly may be variable, ranging from webbing of skin and other soft tissues to fusion of bone within the affected fingers or toes. Affected individuals can also have extra fingers and/or toes (polydactyly). In addition, the fingers and toes may appear unusually short (brachydactyly), particularly due to abnormalities of the bones within the hands and feet.Some individuals may have additional physical abnormalities including delayed bone age, incomplete closure of the roof of the mouth (cleft palate), and a dislocated elbow. In some affected males, the testes may fail to descend into the scrotum (cryptorchidism). In one report, skin and teeth abnormalities were also noted.
