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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2024The c.4321G>A (p.A1441T) alteration is located in exon 34 (coding exon 32) of the ARAP1 gene. This alteration results from a G to A substitution at nucleotide position 4321, causing the alanine (A) at amino acid position 1441 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
