Genes affected
NPHS1 (HGNC:7908): (NPHS1 adhesion molecule, nephrin) This gene encodes a member of the immunoglobulin family of cell adhesion molecules that functions in the glomerular filtration barrier in the kidney. The gene is primarily expressed in renal tissues, and the protein is a type-1 transmembrane protein found at the slit diaphragm of glomerular podocytes. The slit diaphragm is thought to function as an ultrafilter to exclude albumin and other plasma macromolecules in the formation of urine. Mutations in this gene result in Finnish-type congenital nephrosis 1, characterized by severe proteinuria and loss of the slit diaphragm and foot processes.[provided by RefSeq, Oct 2009]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 22, 2021For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with congenital nephrotic syndrome (PMID: 11317351). ClinVar contains an entry for this variant (Variation ID: 56520). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Ser231*) in the NPHS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NPHS1 are known to be pathogenic (PMID: 11317351, 11854170, 12039988). -
