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]

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 379 of the NPHS1 protein (p.Arg379Trp). This variant is present in population databases (rs386833871, gnomAD 0.006%). This missense change has been observed in individuals with congenital nephrotic syndrome (PMID: 15338398, 19321760, 31456999, 31788464). ClinVar contains an entry for this variant (Variation ID: 56427). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NPHS1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects NPHS1 function (PMID: 24142548). For these reasons, this variant has been classified as Pathogenic. -
