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 07, 2022The c.4075G>A (p.D1359N) alteration is located in exon 26 (coding exon 25) of the ARAP2 gene. This alteration results from a G to A substitution at nucleotide position 4075, causing the aspartic acid (D) at amino acid position 1359 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
