CACNA1A and epilepsy: CACNA1A gene (OMIM *601011) encodes a voltage‐dependent calcium channel subunit expressed in neuronal tissue and mutations in this gene have been associated with epilepsy (Kors et al., 2004; Zamponi, Lory, & Perez‐Reyes, 2010) and chronic neurological disorders (Ducros et al., 2001; Ophoff et al., 1996; Wan et al., 2011).
