Genes affected

NPHS2 (HGNC:13394): (NPHS2 stomatin family member, podocin) This gene encodes a protein that plays a role in the regulation of glomerular permeability. Mutations in this gene cause steroid-resistant nephrotic syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

This sequence change creates a premature translational stop signal (p.Thr53Profs*46) in the NPHS2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NPHS2 are known to be pathogenic (PMID: 10742096, 14701729, 15253708, 23595123). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with nephrotic syndrome (PMID: 28117080). ClinVar contains an entry for this variant (Variation ID: 495108). For these reasons, this variant has been classified as Pathogenic. -
