ATP1A3 and epilepsy, early-onset: Human mutations in ATP1A3 have previously been discovered in a wide range of autosomal dominant neurological disorders (Heinzen et al., 2014), including encephalopathy with cerebellar ataxia (Sabouraud et al., 2019), AHC (Galaz-Montoya et al., 2019), rapid-onset dystonia Parkinsonism (ADP) (Anselm et al., 2009), cerebellar ataxia (Sabouraud et al., 2019), early-onset epilepsy (Ishihara et al., 2019), and autism spectrum disorder (Torres et al., 2018).
