Genes affected

ARFGAP3 (HGNC:661): (ADP ribosylation factor GTPase activating protein 3) The protein encoded by this gene is a GTPase-activating protein (GAP) that associates with the Golgi apparatus and regulates the early secretory pathway of proteins. The encoded protein promotes hydrolysis of ADP-ribosylation factor 1 (ARF1)-bound GTP, which is required for the dissociation of coat proteins from Golgi-derived membranes and vesicles. Dissociation of the coat proteins is a prerequisite for the fusion of these vesicles with target compartments. The activity of this protein is sensitive to phospholipids. Multiple transcript variants encoding different isoforms have been found for this gene. This gene was originally known as ARFGAP1, but that is now the name of a related but different gene.

The c.1095C>G (p.S365R) alteration is located in exon 12 (coding exon 12) of the ARFGAP3 gene. This alteration results from a C to G substitution at nucleotide position 1095, causing the serine (S) at amino acid position 365 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
