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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2024The c.4474C>T (p.L1492F) alteration is located in exon 33 (coding exon 32) of the ARAP3 gene. This alteration results from a C to T substitution at nucleotide position 4474, causing the leucine (L) at amino acid position 1492 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
