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.Arg196*) 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 present in population databases (rs12568913, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with nephrotic syndrome (PMID: 15780077). ClinVar contains an entry for this variant (Variation ID: 188892). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
