title: The Lesch-Nyhan syndrome: a family study.
abstract: Two brothers were found to have athetoid cerebral palsy, mental and growth retardation and evidence of self mutilation. One had passed a renal calculus and both had high serum uric acid levels. The diagnosis of Lesch-Nyhan syndrome was confirmed by the finding of low levels of hypoxanthine-guanine phosphoribosyl transferase in erythrocytes and by autoradiography of fibriblasts. The mother, maternal grandmother, a female sibling and a maternal aunt were identified as carriers of the X-linked mutation which was responsible for the enzyme deficiency in the two male siblings.
