Genes affected

UBA5 (HGNC:23230): (ubiquitin like modifier activating enzyme 5) This gene encodes a member of the E1-like ubiquitin-activating enzyme family. This protein activates ubiquitin-fold modifier 1, a ubiquitin-like post-translational modifier protein, via the formation of a high-energy thioester bond. Alternative splicing results in multiple transcript variants. A pseudogene of this gene has been identified on chromosome 1. [provided by RefSeq, Feb 2016]

NPHP3-ACAD11 (HGNC:48351): (NPHP3-ACAD11 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring NPHP3 (nephronophthisis 3, adolescent) and ACAD11 (acyl-CoA dehydrogenase family, member 11) genes on chromosome 3. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV006338320: Published functional studies demonstrate a damaging effect with p.(V260M) resulting in significantly reduced catalytic activities (PMID: 27545681, 38079206)
• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_024818.6
• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant 3-132672143-G-A is Pathogenic according to our data. Variant chr3-132672143-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 265752.Status of the report is criteria_provided_single_submitter, 1 stars.
