Genes affected
ARAP1 (HGNC:16925): (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 1) The protein encoded by this gene contains SAM, ARF-GAP, RHO-GAP, ankyrin repeat, RAS-associating, and pleckstrin homology (PH) domains. In vitro, this protein displays RHO-GAP and phosphatidylinositol (3,4,5) trisphosphate (PIP3)-dependent ARF-GAP activity. The encoded protein associates with the Golgi, and the ARF-GAP activity mediates changes in the Golgi and the formation of filopodia. It is thought to regulate the cell-specific trafficking of a receptor protein involved in apoptosis. Multiple transcript variants encoding different isoforms have been found for this gene.

The c.3883C>G (p.P1295A) alteration is located in exon 29 (coding exon 27) of the ARAP1 gene. This alteration results from a C to G substitution at nucleotide position 3883, causing the proline (P) at amino acid position 1295 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
