Genes affected

VAMP8 (HGNC:12647): (vesicle associated membrane protein 8) This gene encodes an integral membrane protein that belongs to the synaptobrevin/vesicle-associated membrane protein subfamily of soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs). The encoded protein is involved in the fusion of synaptic vesicles with the presynaptic membrane.[provided by RefSeq, Jun 2010]

Ambry Genetics

Dec 09, 2023

The c.35G>C (p.R12P) alteration is located in exon 2 (coding exon 2) of the VAMP8 gene. This alteration results from a G to C substitution at nucleotide position 35, causing the arginine (R) at amino acid position 12 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
