NCIt definition : Human SNAP25 wild-type allele is located within 20p12-p11.2 and is approximately 89
kb in length. This allele, which encodes synaptosomal-associated protein 25, is involved
in vesicular trafficking, neurotransmitter release and plasma membrane recycling.
Mutation of the gene may be associated with congenital myasthenic syndrome-18 and
