Furthermore, CT + TT of MECP2 was prominently elevated in nephritis patients (50.8%) compared to non-nephritis patients (27.7%, OR1 = 2.70, p = 0.016) and controls (19%, OR2 = 4.401, p < 0.001), and no significant difference was noted between non-nephritis patients and controls (OR3 = 1.63, p = 0.238). The gene discussed is MECP2; the disease is nephritis.
