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.4558C>A (p.L1520I) alteration is located in exon 33 (coding exon 32) of the ARAP3 gene. This alteration results from a C to A substitution at nucleotide position 4558, causing the leucine (L) at amino acid position 1520 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
