Gene Affected Aspartoacylase (Aspa), Hyperpolarization-activated cyclic nucleotide-gated channel 1 (Hcn1)
Origin This double mutant strain was established by crossing WTC/Kyo (NBRP Rat No. 0020) and F344-Aspaem34Kyo (NBRP Rat No. 0806). WTC/Kyo has a missense mutation (Hcn1A354V) in Hcn1 (Hyperpolarization-activated cyclic nucleotide-gated channel 1) gene and F344-Aspaem34Kyo has a 16-bp deletion in the exon4 of Aspa (Aspartoacylase) gene (c.622_637del).
Strain characteristics This strain has A354V mutation in Hcn1 gene and c.622_637del mutaion in Aspa gene. This double mutant rats show tremor behavior resembling those in TRM/Kyo rats at 3 weeks of age, and this tremor was suppressed by drugs therapeutic for ET (Essential tremor). The Aspa/Hcn1-double mutantcan serve as good animal models of human ET.
