Erythrocyte glutathione peroxidase in subjects of Mediterranean origin. A family study.
Erythrocyte glutathione peroxidase (GSH-Px) was assayed in subjects of Mediterranean origin and the distribution of the data obtained seems to confirm the existence of two alleles coding for low and high enzyme activity. In order to define the limits of expected genotypes less arbitrarily we studied families where parents' genotypes could allow us to define that of the children. Gene frequencies were calculated from genotype frequencies of an unrelated population and from crossings distribution by the Hardy-Weinberg equation. We observed a good agreement between gene frequencies obtained by these two different methods.
