All mutations/alleles(4) : Targeted(4)
Incidental mutations (data from Mutagenetix , APF )
Homozygous mutation of this gene results in central nervous system abnormalities. One model showed delayed synapse formation and decreased brain weight while another allele showed decreased post-tetanic potentiation and increased synaptic depression and development of convulsive seizures.
