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 links:

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]

The c.493C>G (p.L165V) alteration is located in exon 5 (coding exon 5) of the ARL2 gene. This alteration results from a C to G substitution at nucleotide position 493, causing the leucine (L) at amino acid position 165 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
