In symptomatic malaria, the effects of polymorphisms in some genes, including the beta globulin gene (HBB), glucose 6 phosphate dehydrogenase gene (G6PD), mannose-binding lectin gene (MBL2), tumor necrotic factor-alpha (TNF-α) gene, and inducible nitric oxide synthase 2 (NOS2), on providing protection from or enhancing susceptibility to the disease have been identified [8–15]. The gene discussed is G6PD; the disease is malaria.
