title: HLA phenotypes in Mexican Americans with tuberculosis.
abstract: HLA-A, -B, and -C phenotype distributions in 100 Mexican Americans with active tuberculosis were compared with HLA phenotypes in 50 healthy, tuberculin-skin-test-positive and 50 healthy, tuberculin-skin-test-negative Mexican Americans. Although there existed differences in the phenotype frequencies of 5 antigens (Aw30, Aw33, B7, B15, and B17) among the 3 study groups, these differences were not significant using p values that were corrected for the number of antigens tested. Thus, susceptibility (or resistance) to tuberculosis in Mexican Americans does not appear to be linked to a specific HLA-A, -B, or -C phenotype.
