Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_024818.6(UBA5):​c.738A>G​(p.Arg246Arg) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. R246R) has been classified as Likely benign.

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: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BP7: Synonymous conserved (PhyloP=2.26 with no splicing effect.
