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]

Variant summary: NPHS2 c.643C>T (p.Gln215X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 1.2e-05 in 251220 control chromosomes (gnomAD). c.643C>T has been reported in the literature in multiple homozygous and compound heterozygous individuals affected with Nephrotic Syndrome (e.g. Machuca_2009, Jain_2014, Sadowski_2015, Feltran_2017). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and classified the variant as pathogenic / likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Gln215*) 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 (no rsID available, gnomAD 0.003%). This premature translational stop signal has been observed in individuals with nephrotic syndrome (PMID: 18823551, 25852895, 28658201). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 370159). For these reasons, this variant has been classified as Pathogenic. -
