Abstract
The results of immunoglobulin typing of 278 Tuvinians for Glm (f, z, a, and x), G3m (b, 0, 1, 3, 5, c3, 5, g, s, t and v), A2m (1 and 2) and Km (1) indicate these southern Siberians to have the Caucasian haplotype Gmf;b Am1 (0.100), the Oriental haplotypes Gmf;a;b Am1 (0.022), Gmf, a;bAm2(0.040), Gmz, a;b, s, tAm1 (0.027) and Gmz, a;b, s, tAm2 (0.107). The haplotypes distribution for Gmz;a;gAm1 (0.279), Gmz, a; sAm2(0.065), Cm7, a; χ. sAm1(0.101) and Gmz, a,x;gAm2(0.030) are similar to those found in oriental populations. The striking feature of this population is the presence of Gmz, a;b Am1 (0.108) and Gmz, a;b Am2 (0.122) previously thought to be characteristic of African or Papuan populations, indicating that a third focus of the Gmz, a;b haplotypes exists in Central Asia. The Km1frequency observed (0.125) is intermediate between Caucasian and previously studied northern Oriental populations.Keywords
