title: Phenotypic variation in red cell G-6PD deficiency in heterozygotes.
abstract: Erythrocyte G-6PD activity in 69 heterozygotes has a log-normal distribution, a fact which cannot be solely attributed to random X chromosome inactivation. Others factors - genetic and individual - are suggested by intrafamilial clusting and post-natal variability of phenotype.
