Gene Affected
Origin This strain was established by phenotype-driven ENU mutagenesis.
Strain characteristics ADMS rats dominantly exhibited myokymia, neuromyotonia and generalized tonic-clonic seizures. They also showed cold stress-induced tremor, neuromyotonia, and motor incoordination.
Key words: myokymia, neuromyotonia, epilepsy
Breeding Conditions Good breeding performance until seizure onset (about 4 or 5 months of age). Heterozygous females have less performance of nursing behavior for their pups.
Genotyping Genotyping protocol for Kcna1
