Abstract
Focal epilepsy is the most common type of epilepsy accounting for 60–70% of all cases of this pathology. We present two familial cases of focal epilepsy associated with a nucleotide sequence variant in DEPDC5 gene. Clinical and ancestry examination was performed by using instrumental (magnetic resonance imaging, video-electroencephalography) and genetic testing methods. The nucleotide sequence variants in DEPDC5 gene were found in two probands and paired fathers with epilepsy. Focal cortical dysplasia was detected only in the father of Proband 1 as well as Proband 2 with resistant epilepsy and severe cognitive deficit. Hence, such clinical cases confirm that pathogenic variants in DEPDC5 gene are related with familial focal epilepsy, which clinical manifestation may depend on the type of identified mutation. The study of genotype-phenotype correlations is necessary to apply proper therapy. Before surgical treatment of epilepsy, the genetic testing by whole exome or whole genome sequencing should be performed.
