We found that tremor was phenocopied by neuronal inhibition with UAS-Kir2.1 (P<0.05; n=18) and ablation with UAS-Hid (P<0.01; n=6), but not by neuronal activation with UAS-TrpA1 (Fig. 1H), suggesting that the tremor phenotype is induced by neuronal hypoactivation. The gene discussed is GJB2; the disease is Tremor.
