HLA-C and tuberculosis: First, we identified four MHC alleles (Susu-DRB*01, Susu-DRB*03, Susu-DRB*07 and Susu-DRB*13; Fig. 3a), six supertypes (ST01, ST02, ST03, ST04, ST05 and ST09; Supplementary Fig. 3a) and one haplotype (F; Supplementary Fig. 4a) to be repeatedly associated with clinical signs of TB over the 20 years studied since 1999.
