Genes affected

ARL4A (HGNC:695): (ADP ribosylation factor like GTPase 4A) ADP-ribosylation factor-like 4A is a member of the ADP-ribosylation factor family of GTP-binding proteins. ARL4A is similar to ARL4C and ARL4D and each has a nuclear localization signal and an unusually high guaninine nucleotide exchange rate. ARL4A is located in both the nuclear and extranuclear cell compartments. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

The c.391A>G (p.I131V) alteration is located in exon 2 (coding exon 1) of the ARL4A gene. This alteration results from a A to G substitution at nucleotide position 391, causing the isoleucine (I) at amino acid position 131 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
