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]

The c.106G>T (p.A36S) alteration is located in exon 2 (coding exon 2) of the ADAP2 gene. This alteration results from a G to T substitution at nucleotide position 106, causing the alanine (A) at amino acid position 36 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
