Genes affected

ARL6IP5 (HGNC:16937): (ADP ribosylation factor like GTPase 6 interacting protein 5) Expression of this gene is affected by vitamin A. The encoded protein of this gene may be associated with the cytoskeleton. A similar protein in rats may play a role in the regulation of cell differentiation. The rat protein binds and inhibits the cell membrane glutamate transporter EAAC1. The expression of the rat gene is upregulated by retinoic acid, which results in a specific reduction in EAAC1-mediated glutamate transport. [provided by RefSeq, Jul 2008]

The c.374G>A (p.G125D) alteration is located in exon 2 (coding exon 2) of the ARL6IP5 gene. This alteration results from a G to A substitution at nucleotide position 374, causing the glycine (G) at amino acid position 125 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
