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.3568C>T (p.H1190Y) alteration is located in exon 26 (coding exon 24) of the ARAP1 gene. This alteration results from a C to T substitution at nucleotide position 3568, causing the histidine (H) at amino acid position 1190 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
