• Consequence: NPHS2 NM_014625.4 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1 O:1
• Conservation: PhyloP100: 5.64

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

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.898

Significance: drug response

Review Status: no assertion criteria provided

Collection Method: research

Depending upon patients response to standard corticosteroids therapy, they were classified to be either Steroid resistance(SRNS) or steroid sensitive(SSNS) likley responsive,remission within 4 weeks of corticosteroid therapy ,therefore classified as steroid sensitive nephrotic syndrome (SSNS)
