- This study evaluated the association between the guanine-thymine (GT) repeat polymorphism in intron II of the Toll-like receptor 2 (TLR2) gene and lung disease caused by nontuberculous mycobacteria (NTM). Polymerase chain reaction and gene scans were used to determine the numbers of GT repeats for 193 patients with the nodular bronchiectatic form of NTM lung disease, including 110 patients with Mycobacterium avium-intracellulare (MAC) infection, 82 patients with Mycobacterium abscessus infection, and 1 patient with co-infection of both organisms. These values were compared with the results for 191 controls. Genotypes with shorter GT repeats were more common among patients with NTM lung disease (50.8 vs 37.7%, p=0.01). In the subgroup analysis, genotypes that included S alleles were more common in the patients with MAC lung disease (53.6%, p=0.01, OR, 1.91; 95% CI, 1.16, 3.16) than in healthy controls, whereas this difference was not statistically significant in patients with M. abscessus lung disease (47.6%, p=0.13). In conclusion, these results suggest that the GT repeat microsatellite polymorphisms in intron II of the human TLR2 gene contribute to the development of NTM lung disease, especially MAC lung disease, in a Korean population.
