Genes affected

RAP1GAP2 (HGNC:29176): (RAP1 GTPase activating protein 2) This gene encodes a GTPase-activating protein that activates the small guanine-nucleotide-binding protein Rap1 in platelets. The protein interacts with synaptotagmin-like protein 1 and Rab27 and regulates secretion of dense granules from platelets at sites of endothelial damage. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

Sep 03, 2024

The c.250G>A (p.D84N) alteration is located in exon 6 (coding exon 6) of the RAP1GAP2 gene. This alteration results from a G to A substitution at nucleotide position 250, causing the aspartic acid (D) at amino acid position 84 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
