MGI Phenotype FUNCTION: This gene encodes a protein associated with low seizure threshold in mice and may contribute to susceptibility to epilepsy. [provided by RefSeq, Aug 2011]
PHENOTYPE: Mice homozygous for mutations in this gene display increased susceptibility to induced seizures. Mice homozygous for null mutations also display partial penetrance of prenatal lethality. [provided by MGI curators]
