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]

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

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 17 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-179551373-CA-C is Pathogenic according to our data. Variant chr1-179551373-CA-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 447884.Status of the report is criteria_provided_single_submitter, 1 stars.
