Genes affected

ARAP3 (HGNC:24097): (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 3) This gene encodes a phosphoinositide binding protein containing ARF-GAP, RHO-GAP, RAS-associating, and pleckstrin homology domains. The ARF-GAP and RHO-GAP domains cooperate in mediating rearrangements in the cell cytoskeleton and cell shape. It is a specific PtdIns(3,4,5)P3/PtdIns(3,4)P2-stimulated Arf6-GAP protein. An alternatively spliced transcript has been found for this gene, but its biological validity has not been determined. [provided by RefSeq, Sep 2015]

The c.3676C>T (p.R1226W) alteration is located in exon 27 (coding exon 26) of the ARAP3 gene. This alteration results from a C to T substitution at nucleotide position 3676, causing the arginine (R) at amino acid position 1226 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
