We also observed occasional seizures in the home cage for all genotypes in which Fgf13 was ablated in interneurons (Nestin-Fgf13 cKO, Nkx2.1-Fgf13 cKO, and Gad2-Fgf13 cKO) and often discovered dead mice, which we suspect was a SUDEP phenotype due to recurrent seizures, given that recurrent uncontrolled seizures are a major risk factor for sudden death (Devinsky et al., 2016; Richerson, 2023). Here, FGF13 is linked to Sudden unexpected death in epilepsy.
