Some candidate genes for susceptibility to tuberculosis
| HLA | Complement receptor 1 |
| NRAMP1 | ICAM 1 |
| Tumour necrosis factor | Fucosyltransferase 2 |
| Mannose binding protein | Inducible nitric oxide synthase |
| Vitamin D receptor | Chemokine receptors |
| Interferon-γ receptor | Interleukin 4 |
| Interleukin 10 | TH2 cluster |
| Interleukin 1α, 1β and RA | Interleukin 6 |
The candidate genes listed all contain known polymorphisms. Many other genes could play a role in tuberculosis susceptibility and are worthy of investigation.
