Gene Affected Atm: ataxia telangiectasia mutated
Origin This rat strain was established by ZFN method targeting rat Atm gene (resulting in a 8-bp deletion of exon13). Background strain: F344/Stm
Strain characteristics Ataxia-telangiectasia (A-T) model. Atm knockout rat does not display cerebellar atrophy but instead paralysis and spinal cord atrophy. Loss of Atm in neurons and glia leads to accumulation of cytosolic DNA, increased cytokine production and constitutive activation of microglia consistent with a neuroinflammatory phenotype. Rats lacking ATM had significant loss of motor neurons and microgliosis in the spinal cord, consistent with onset of paralysis.  Atm KO rats also developed lymphomas and occasional solid tumours similar to the cancer types seen in A-T patients. Other detailed phenotypes are described in the reference article. (March 2017)
Breeding Conditions Mmintained by crossing between Atm heterozygous rats. (Homozygous rats are infertility.)
Genotyping Genotyping protocol for Atm
