Genes affected

ARAP2 (HGNC:16924): (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 2) The protein encoded by this gene contains ARF-GAP, RHO-GAP, ankyrin repeat, RAS-associating, and pleckstrin homology domains. The protein is a phosphatidylinositol (3,4,5)-trisphosphate-dependent Arf6 GAP that binds RhoA-GTP, but it lacks the predicted catalytic arginine in the RHO-GAP domain and does not have RHO-GAP activity. The protein associates with focal adhesions and functions downstream of RhoA to regulate focal adhesion dynamics. [provided by RefSeq, Sep 2008]

The c.4397G>A (p.G1466E) alteration is located in exon 28 (coding exon 27) of the ARAP2 gene. This alteration results from a G to A substitution at nucleotide position 4397, causing the glycine (G) at amino acid position 1466 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
