However, Delgado did not find any significant association between TB and TNF-857 in Cambodian population.[16] We also found no significant association between the TNF-238, TNF-308 polymorphisms with TB, which is consistent with some previous studies.[15][16][17][18][19] Selvaraj showed that none of the TNF-238 and TNF-308 polymorphisms were associated with pulmonary TB. This evidence concerns the gene TNF and pulmonary tuberculosis.
