Polymorphisms in CCL5 promoter are associated with pulmonary tuberculosis in northern Spain.

Abstract

Our findings indicate that CCL5 may play a role in conferring susceptibility to active PTB. Thus, the -403G and -28C alleles, either separately or combined in the G-C haplotype and the GG/CC diplotype, may be related to protection against PTB. By contrast, the -403A and -28G alleles, the G-G or A-C haplotypes and the G/G-G/G and A/A-C/C diplotypes may confer susceptibility to PTB.
