Recent studies have demonstrated that the studied IL2 promoter variant (rs2069762T/G) is associated with Helicobacter pylori infection [40], multiple sclerosis [41], pathogenesis of childhood lymphoma [42], pathogenesis of new-onset diabetes after transplantation (NODAT) [43], measles-specific cellular immunity [44], a higher risk of acute rejection episodes during kidney transplantation [45] and in allergic disorders [46]. The gene discussed is IL2; the disease is multiple sclerosis.
