Abstract
Abstract As a part of investigating genetic markers in bloods from Ryukyuans, red cell GPT (glutamic-pyruvic transaminase) and GOT (glutamic-oxaloacetic transaminase) polymorphisms were examined in 765 samples collected in Ishi-gaki Island.
In GPT system, the gene frequencies observed were Gpt1=0.535 and Gpt2=0.465, and in GOT system, only two phenotypes, GOT 1 and 2-1, were identified.Compared with other populations of this country, most notable features for this Ryukyuan population were to have the lowest value for the Gptl frequency and the highest for the Gpt2 frequency and to show apparent lack of the Got3 gene.Some comments on the GPT gene distribution are described.
