Genes affected

AXDND1 (HGNC:26564): (axonemal dynein light chain domain containing 1)

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: Illumina, Labcorp Genetics (formerly Invitae), Myriad Women’s Health, Ambry Genetics, G2P
• familial idiopathic steroid-resistant nephrotic syndrome

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Pathogenic. The variant received 14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 1-179552602-C-A is Pathogenic according to our data. Variant chr1-179552602-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1409729.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
