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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2024The c.4736A>G (p.N1579S) alteration is located in exon 32 (coding exon 31) of the ARAP2 gene. This alteration results from a A to G substitution at nucleotide position 4736, causing the asparagine (N) at amino acid position 1579 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
