Genetic polymorphisms of CCL2, CCL5, CCR2 and CCR5 genes in Sahariya tribe of North Central India: An association study with pulmonary tuberculosis

► We genotyped polymorphisms of chemokines and their receptor gene in Sahariya tribe. ► We found significant association of -403G/A SNP of CCL5 with susceptibility to TB. ► We found significant association of V64I SNP of CCR2 with resistance to TB. ► The AA genotype of V64I showed significant protection against high bacillary load.
