KCNA1 and Sudden unexpected death in epilepsy: Mice lacking Kv1.1 due to global Kcna1 gene knockout (KO; i.e., Kcna1–/–) exhibit spontaneous seizures with cardiorespiratory dysfunction, brain‐driven autonomic cardiac abnormalities, and premature seizure‐related death, making them a frequently used model for exploring neuro‐cardio‐respiratory mechanisms associated with SUDEP risk (Dhaibar et al., 2019; Glasscock et al., 2010; Hutson et al., 2020; Iyer et al., 2020; Moore et al., 2014; Simeone et al., 2018).
