Red cell glucose-6-phosphate dehydrogenase phenotypes in several Mongoloid populations of eastern India
A total of 954 subjects of both sexes from nine Mongoloid tribes of eastern India were investigated for the distribution of red cell glucose-6-phosphate dehydrogenase (G6PD) phenotypes by starch-gel electrophoresis. The incidence of Gd- was found to be 8% in the Khasi, 6% in the Nishi, 5% in Apatani and 3% in Adi. The small group of Bodo and the mixed group of other Arunachal tribes had Gd- frequencies of 19% and 15%, respectively. Only one isola…
Genetic studies among the Nagas and Hmars of eastern India
A total of 148 Nagas (65 urban and 83 rural) and 81 Hmars from northeastern India were tested for 15 blood genetic markers. Both the Nagas and Hmars lacked haemoglobin variants and G6PD deficiency and had a high frequency of PGD C . This may be attributed to selective pressures operating at these loci. Genetic distance estimates using 41 alleles at 11 polymorphic loci showed appreciable heterogeneity between the urban and rural Nagas that were in…
