Genes affected

VAMP3 (HGNC:12644): (vesicle associated membrane protein 3) Synaptobrevins/VAMPs, syntaxins, and the 25-kD synaptosomal-associated protein are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane. This gene is a member of the vesicle-associated membrane protein (VAMP)/synaptobrevin family. Because of its high homology to other known VAMPs, its broad tissue distribution, and its subcellular localization, the protein encoded by this gene was shown to be the human equivalent of the rodent cellubrevin. In platelets the protein resides on a compartment that is not mobilized to the plasma membrane on calcium or thrombin stimulation. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 18, 2023

The c.202A>G (p.K68E) alteration is located in exon 3 (coding exon 3) of the VAMP3 gene. This alteration results from a A to G substitution at nucleotide position 202, causing the lysine (K) at amino acid position 68 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
