Table 1 Distribution of genotype and allele frequency of CCR5, CCR2 and SDF-1 genes in primitive tribe (Baiga) and non-primitive tribe (Gond) of Central India

From: Low prevalence of CCR5-Δ32, CCR2-64I and SDF1-3′A alleles in the Baiga and Gond tribes of Central India

Sr. No. Tribe N CCR5 CCR2 SDF1
Genotype MAF χ2 (H.W.) Genotype MAF χ2 (H.W.) Genotype MAF χ2 (H.W.)
CCR5 Δ32 GG AG AA GG AG AA
1. Baiga 100 100 0 0 93 7 0 0.035 0.720 84 16 0 0.080 0.390
2. Gond 100 100 0 0 79 20 1 0.110 0.830 82 17 1 0.100 0.910
  1. Major alleles for CCR5, CCR2 and SDF1 are wild type (wt), “G” and “G” respectively. Minor alleles for CCR5, CCR2 and SDF1 are “Δ32” (CCR5-Δ32), “A” (V → I) and “A” (SDF1-3A) respectively
  2. MAF and H.W. represents minor allele frequency and Hardy–Weinberg respectively
