Mice homozygous for a single point mutation show slow postnatal weight gain, abnormal hippocampus CA1 region morphology, cognitive deficits, and environmentally induced seizures. Homozygosity for the p.R506* mutation leads to hyperactivity, decreased anxiety, lower chemically induced seizure threshold and stimuli-induced seizures.
