Marked advances in molecular biology are constantly enabling new insights into renal pathophysiology and the treatment of human disease. In the December 2006 issue of Nature Genetics, Hinkes et al. [1] describe a novel mechanism for early nephrotic syndrome in children due to mutations in PLCE1, a gene which encodes one of a family of phospholipase C enzymes (PLC
1). Affected children develop proteinuria by four years of age, with renal pathology demonstrating diffuse mesangial sclerosis (truncating mutations) or focal segmental glomerulosclerosis (missense mutations). The majority progress to end-stage renal disease by 5 years of age; however, of particular interest is that two children, both with truncating mutations in PLCE1, responded to treatment with | Nephrotic syndrome and the glomerular filtration barrier: is the podocyte slit diaphragm the principal determinant? |
