Genes affected

UBE2F (HGNC:12480): (ubiquitin conjugating enzyme E2 F (putative)) Enables NEDD8 conjugating enzyme activity. Involved in protein neddylation. Predicted to be located in cytosol. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

UBE2F-SCLY (HGNC:48339): (UBE2F-SCLY readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring UBE2F (ubiquitin-conjugating enzyme E2F) and SCLY (selenocysteine lyase) genes on chromosome 2. The read-through transcript is a candidate for non-sense mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.41258898).
