Third, anti-nephrin antibody detection could diagnose cases of coexisting glomerular diseases such as concomitant antibodies against PLA2R and nephrin or concomitant genetic disease, in which the histological picture of membranous nephropathy or the genetic diagnosis would overrule the diagnosis of an autoimmune form of minimal change disease. This evidence concerns the gene NPHS1 and membranous glomerulonephritis.
