title: A genetic study among the Lepchas of the Darjeeling area of eastern India.
abstract: A total of 215 Lepchas (75 Buddhists and 140 Christians) living in the Kalimpong subdivision, Darjeeling district, West Bengal, India, were investigated for the distribution of haemoglobin, serum proteins and red cell enzymes. The gene frequencies were as follows: HbE = 0.02; Hp1 = 0.18; TfB = 0.007; TfDChi = 0.005; Gc2 = 0.22; pa = 0.18; pc = 0.03; PGM2(1) = 0.18; PGM6(1) = 0.002; PGDc = 0.17; AK2 = 0.02; GLO1 = 0.21. The most striking features were the complete lack of G6PD deficiency and very high frequency of PGDC. The remaining loci (serum albumin, lactate dehydrogenase, malate dehydrogenase and glucose-6-phosphate dehydrogenase, phosphohexose isomerase and superoxide dismutase) were monomorphic. The gene frequencies were similar in the Buddhist and Christian Lepchas. The observed average heterozygosity (9 loci) was 0.20 in the entire sample.
