title: Lesch-Nyhan syndrome: rapid detection of heterozygotes by use of hair follicles.
abstract: A method is described which permits rapid phenotypic diagnosis of the Lesch-Nyhan heterozygote by direct assay of hypoxanthine guanine phosphori-bosyltransferase activity in single hair follicles obtained from the scalp.
