Polymorphisms in TICAM2 and IL1B are associated with TB
BACKGROUND: Human genetic susceptibility for tuberculosis (TB) has been demonstrated by several studies, but few have examined multiple innate and adaptive immunity genes comprehensively, age-specific effects, and/or resistance to Mycobacterium tuberculosis (Mtb) infection (RSTR). We hypothesized th...

description | BACKGROUND: Human genetic susceptibility for tuberculosis (TB) has been demonstrated by several studies, but few have examined multiple innate and adaptive immunity genes comprehensively, age-specific effects, and/or resistance to Mycobacterium tuberculosis (Mtb) infection (RSTR). We hypothesized that RSTR, defined by a persistently negative tuberculin skin test, may have different genetic influences than Mtb disease. METHODS: We examined 29 candidate genes in pathways that mediate immune responses to Mtb in subjects in a household contact study in Kampala, Uganda. We genotyped 546 haplotype-tagging single nucleotide polymorphisms (SNPs) in 835 individuals from 481 families; 28.7% had TB, 10.5% were RSTR, and the remaining 60.8% had latent Mtb infection. RESULTS: Among our most significant findings were SNPs in TICAM2 (p=3.6×10(−6)) and IL1B (p=4.3×10(−5)) associated with TB. Multiple SNPs in IL4 and TOLLIP were associated with TB (p<0.05). Age-genotype interaction analysis revealed SNPs in IL18 and TLR6 that were suggestively associated with TB in children ≤ 10 years old (p=2.9×10(−3)). By contrast, RSTR was associated with SNPs in NOD2, SLC6A3 and TLR4 (nominal p < 0.05); these genes were not associated with TB, suggesting distinct genetic influences. CONCLUSIONS: We report the first association between TICAM2 polymorphisms and TB, and between IL18 and pediatric TB. |
