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 18 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-179552601-A-T is Pathogenic according to our data. Variant chr1-179552601-A-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 552884.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
