MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a synaptic vesicle membrane protein. The encoded protein is thought to function as a calcium sensor in vesicular trafficking and exocytosis. Mutations in this gene are associated with myasthenic syndrome, presynaptic, congenital, with or without motor neuropathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]
PHENOTYPE: Mice homozygous for an ENU-induced allele are viable but sterile, weigh less and show ataxia and altered spontaneous and Ca2+-evoked neurotransmitter release. Mice homozygous for a null allele die at weaning showing growth arrest, motor dysfunction and impaired Ca2+-evoked neurotransmitter release. [provided by MGI curators]
