Thirty-five tag single-nucleotide polymorphisms (SNPs) across 11 candidate cytokines and related genes, including IL-12/IFN-γ axis genes (IL12B, IL12RB1, IL18R1, IL27, IFNGR1, IFNGR2 and STAT1), the TNF gene locus (TNF and LTA), IL10, and CCL2, were genotyped using Sequenom's iPLEX assays in 1,032 patients with TB and 1,008 controls of Chinese Han origin. The gene discussed is IL10; the disease is tuberculosis.
