Qi H et al. [15] investigated the association between susceptibility to TB and single-nucleotide polymorphisms (SNPs) of the IL-4 (rs2243250, rs2243268, rs2243274, and rs2243282) and IL-10 genes (rs1800871, rs3021094, and rs3790622) in Chinese population, and found that rs2243268-A and rs2243274-G of the IL-4 gene reduced the risk of developing EPTB and severe TB. The gene discussed is IL4; the disease is tuberculosis.
