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:):

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 47 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-132660626-GC-G is Pathogenic according to our data. Variant chr3-132660626-GC-G is described in ClinVar as [Pathogenic]. Clinvar id is 1971012.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change creates a premature translational stop signal (p.Ser30Argfs*14) in the UBA5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in UBA5 are known to be pathogenic (PMID: 27545674, 27545681). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with UBA5-related conditions. For these reasons, this variant has been classified as Pathogenic. -
