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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 29 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: 0.68612 (below the threshold of 3.09). Trascript score misZ: 0.038296 (below the threshold of 3.09). GenCC associations: The gene is linked to nephrotic syndrome, type 2, familial idiopathic steroid-resistant nephrotic syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.16278547).
