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 missense varaint (c.851C>T, p.Ala284Val) has not been observed in population databases (gnomAD) but has been reported in the literature (PMID 20947785, 26455708, others). Variant prediction programs suggest a deleterious effect, although no functional studies have been reported. This change was identified in an affected patient. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in at least one individual with clinical features associated with this gene. In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. The variant is located in a region that is considered important for protein function and/or structure. -

This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 284 of the NPHS2 protein (p.Ala284Val). This variant is present in population databases (rs780761368, gnomAD 0.0009%). This missense change has been observed in individuals with clinical features of steroid-resistant nephrotic syndrome (PMID: 11805166, 16354237, 18823551, 23349334, 23515051, 29982877). It has been reported in trans with the variant p.Arg229Gln in related affected individuals. This suggests that the combination of p.Arg229Gln and this variant may be clinically significant. ClinVar contains an entry for this variant (Variation ID: 562398). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt NPHS2 protein function with a positive predictive value of 95%. This variant has been shown to alter NPHS2 (podocin) protein function, resulting in podocin mislocalization when in combination with p.Arg229Gln-podocin (PMID: 24509478). For these reasons, this variant has been classified as Pathogenic. -

Variant summary: NPHS2 c.851C>T (p.Ala284Val) results in a non-conservative amino acid change located in the Band 7 domain (IPR001107) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 150926 control chromosomes (gnomAD v3.1, genomes dataset). The variant, c.851C>T, has been reported in the literature in multiple homozygous individuals affected with Nephrotic Syndrome Type 2, which progressed to end-stage renal disease (e.g. Tsukaguchi_2002, Karle_2002, Kitzler_2018). This variant was also reported in compound heterozygous state in numerous patients with a well-reported, frequent, genotype-dependent risk variant p.R229Q (e.g. Tsukaguchi_2002, Machuca_2009, Santin_2011), and occasionally also with other (potentially) pathogenic variants in trans (e.g. Park_2020). These data indicate that the variant is very likely to be associated with disease. An extensive study performed by Tory_2014, demonstrated that the A284V podocin protein was mislocalized in the cytoplasmic compartment (either when coexpressed with the WT or with the R229Q podocin), in contrast, while WT podocin reached the plasma membrane, podocin R229Q was retained in the cytoplasm in cells coexpressing podocin A284V (on the other hand, both the WT podocin and podocin R229Q were localized to the plasma membrane when coexpressed together); authors concluded that these interactions mimicked a dominant-negative effect of A284V on the R229Q variant protein. Four other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and classified the variant as pathogenic (n=3) / likely pathogenic (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -
