Abstract
Tuberculosis (TB) caused by Mycobacterium tuberculosis is a major cause of morbidity and mortality worldwide. Thus far, many candidate genes have been investigated for their possible association with TB. Dendritic cell–specific ICAM-3 grabbing nonintegrin (DC-SIGN) encoded by CD209 is the major receptor of M tuberculosis on human dendritic cells. Previous studies reported inconsistent results on the association between CD209 polymorphisms and TB. We examined whether 9 single nucleotide polymorphisms (SNPs) of CD209 are associated with TB in 2 southeast Asian populations (Indonesian and Vietnamese) by Fisher's exact test. The SNP at −939 in the promoter region exhibited a significant association with TB in Indonesian (GG vs GA + AA, p = 0.0051, odds ratio [OR] = 0.68, 95% confidence interval [CI] = 0.52–0.89) but not in Vietnamese populations. Further extensive studies are required to confirm the contribution of CD209 polymorphisms to TB susceptibility.
