Genes affected

ARL2 (HGNC:693): (ADP ribosylation factor like GTPase 2) This gene encodes a small GTP-binding protein of the RAS superfamily which functions as an ADP-ribosylation factor (ARF). The encoded protein is one of a functionally distinct group of ARF-like genes. [provided by RefSeq, Jul 2008]

ARL2-SNX15 (HGNC:49197): (ARL2-SNX15 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring ADP-ribosylation factor-like 2 (ARL2) and sorting nexin 15 (SNX15) genes on chromosome 11. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

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=0.2927407).
