A clinical case of familial temporal epilepsy type 5 (OMIM 614417) with onset at the age of 14 years is described for the first time in the domestic literature. The leading manifestations of the disease were focal seizures of systemic vertigo, accompanied by vestibular ataxia and, sometimes, vomiting. Cognitive and emotional disturbances were observed as well. On the EEG of wakefulness and sleep, a non-expressed epileptiform activity was detected in the left parietotemporal and frontotemporal zone. Neuroimaging did not show any significant changes. Only a molecular genetic study that identified CPA6 gene mutation made it possible to establish the accurate diagnosis.
