One more case of a severe lethal condition resembling the Smith-Lemli-Opitz, type II syndrome

A male child with a lethal multiple congenital anomaly syndrome of facial dysmorphism, ambiguous genitalia, syndactyly and postaxial polydactyly is presented. He had findings consistent with the diagnosis of Smith-Lemli-Opitz type II syndrome. Similar changes were observed in his elder sister, who died when she was 2 months old. On the basis of this familial observation the nosology of Smith-Lemli-Opitz syndrome is discussed.
