Gene Affected ラット Gad2遺伝子
Origin Knockout rats in which the Gad2 gene was disrupted using the TALEN.
Strain characteristics Glutamate decarboxylase (GAD; there are two isoforms, GAD65 and GAD67) is an enzyme that synthesizes the neurotransmitter GABA. In this strain, the Gad2 gene encoding GAD65 was knocked out. In homozygous rats, a high rate of epileptic seizures was observed at 2 to 3 weeks of age.
Breeding Conditions Most of the homozygous rats die as juveniles. This strain is maintained in heterozygotes.
Genotyping Genotyping using PCR.
References Rats deficient in the GAD65 isoform exhibit epilepsy and premature lethality.
