Distribution of Human Zn-Alpha-2-Glycoprotein Types in Chinese and Korean Populations

Abstract
The genetic variation in Zn-α2-glycoprotein (ZAG) was investigated by polyacrylamide gel isoelectric focusing and immunoblotting. The samples comprised 590 Chinese from 2 localities (Shenyang: n = 390; Kaohsiung: n = 200) and 873 Koreans from 2 localities (Seoul: n = 523; Cheju: n = 350). The allele frequencies were: ZAG*1 = 0.9962, ZAG*5 = 0.0038 in Shenyang; ZAG*1 = 1.0000 in Kaohsiung; ZAG*1 = 0.9971, ZAG*3 – 0.0029 in Seoul, and ZAG*1 = 0.9929, ZAG*3 = 0.0071 in Cheju.
