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:2

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Feb 24, 2020	Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 15906409, 20172850, 27019444, 20507940) -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Feb 01, 2023	For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Ser572 amino acid residue in NPHS1. Other variant(s) that disrupt this residue have been observed in individuals with NPHS1-related conditions (PMID: 18503012, 26248470), which suggests that this may be a clinically significant amino acid residue. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 56447). This missense change has been observed in individual(s) with congenital nephrotic syndrome (PMID: 15906409, 20172850, 29474669). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs386833889, gnomAD 0.002%). This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 572 of the NPHS1 protein (p.Ser572Asn). -
