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]

NPHS2 Gene-Disease associations (from GenCC):

• nephrotic syndrome, type 2

  Inheritance: AR, AD Classification: DEFINITIVE, STRONG, LIMITED Submitted by: Myriad Women’s Health, Ambry Genetics, Labcorp Genetics (formerly Invitae), Illumina, G2P
• familial idiopathic steroid-resistant nephrotic syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.32).
