Studies on the Immunoglobulin Allotypes of Asiatic Populations II.

Abstract

The distributions of Gm(a, x, f, b, c, g, and t) and Inv(l) allotypic markers have been examined in 512 Chinese classified as to province of origin. The results indi cate a south to north cline, extending from southernmost to northern China in which Gmag changes from 0.12 to 0.55, Gmaxg from 0.04 to 0.15, Gmabst from 0.04 to 0.12 and Gmafb from 0.80 to 0.22. In contrast to the Gm system, there does not appear to be any significant regional variation in the frequency of Inv1 among Chinese.
