Genes affected
ADAP2 (HGNC:16487): (ArfGAP with dual PH domains 2) The protein encoded by this gene binds beta-tubulin and increases the stability of microtubules. The encoded protein can also translocate to the cell membrane and bind phosphatidylinositol 3,4,5-trisphosphate (PtdInsP3) and inositol 1,3,4,5-tetrakisphosphate (InsP4). In addition, this protein is a GTPase-activating protein for ADP ribosylation factor 6 and may be able to block the entry of some RNA viruses. [provided by RefSeq, Oct 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.217A>G (p.I73V) alteration is located in exon 2 (coding exon 2) of the ADAP2 gene. This alteration results from a A to G substitution at nucleotide position 217, causing the isoleucine (I) at amino acid position 73 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
