We recently demonstrated that aspartoacylase (Aspa) and hyperpolarization-activated cyclic nucleotide-gated potassium channel 1 (Hcn1) genes were causative of essential tremor (ET) in rats. This finding was obtained using Aspaem34Kyo/Hcn1A354V double-mutant rats, but they were bred on a heterogeneous genetic background
