CACNA1A and Focal impaired awareness seizure: Our findings showed that the common types of seizures in epileptic patients with CACNA1A mutations are generalized seizures (absence seizures, myoclonic-astatic, and generalized tonic–clonic) and focal seizures (complex partial seizure, atypical focal seizures, focal myoclonic seizures, and focal (tonic or clonic) seizures), respectively (Fig. 3).
