Genetic studies of red cell glutamic-pyruvic transaminase in some Japanese populations.

Comparative data on the allelic distribution of human red cell GPT were presented for inhabitants of isolated communities and individuals in the general population of Japan. In addition, a quantitative enzyme assay of the different phenotypes was carried out on some of the samples tested. The existence of two heterozygotes with a silent allele, Gpt0, appeared to be confirmed by pedigree analysis.
