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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 19, 2024The c.225G>C (p.K75N) alteration is located in exon 3 (coding exon 3) of the VAMP8 gene. This alteration results from a G to C substitution at nucleotide position 225, causing the lysine (K) at amino acid position 75 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
