The spectrum of severity extends from prenatal death with holoprosencephaly or other lethal malformations, to patients with minimal physical abnormalities and normal intelligence or minimal intellectual impairment. Congenital heart defect is found in half of the Smith-Lemli-Opitz syndrome patients.
