CACNA1G and Parkinson disease: The T-type calcium channel, Cav3.1, has been previously implicated in neuronal autorhythmicity [60, 61] and is thought to underlie tremors seen in Parkinson’s disease [62], enhanced physiological tremor, and in ET [63] and T-type calcium channel antagonists have been shown to reduce tremor in mouse models of ET [61, 64, 65].
