Genetic risk factors in lupus nephritis and IgA nephropathy--no support of an overlap.

<h4>Background</h4>IgA nephropathy (IgAN) and nephritis in Systemic Lupus Erythematosus (SLE) are two common forms of glomerulonephritis in which genetic findings are of importance for disease development. We have recently reported an association of IgAN with variants of TGFB1. In severa...
