MECP2 and nephritis: The T allele frequency of MECP2 rs2734647 was significantly higher in nephritis patients (33.3%) than in non-nephritis patients (14.9%, OR1 = 2.857, p = 0.002) or controls (11%, OR2 = 4.045, p < 0.001), although the T allele difference between non-nephritis patients and controls was not significant (OR3 = 1.416, p = 0.344).
