Researchers from the European Molecular Biology Laboratory [EMBL] and the University of Michigan have discovered a gene that protects us against a serious kidney disease. In the current online issue of Nature Genetics they report that mutations in the gene cause nephronopthisis [NPHP] in humans and mice. NPHP is a disease marked by kidney degeneration during childhood that leads to kidney failure requiring organ transplantation. The insights might help develop effective, noninvasive therapies.
