Abstract

PCDH19-related epilepsy is an inherited disease occurring in female patients and characterized by early onset seizure, intellectual disability, and behavioral disturbances. It is caused by de novo or familial heterozygous variation of the PCDH19 gene located on Xq22.1. Our patient was hospitalized for multiple focal seizures. The magnetic resonance imaging was normal and electroencephalogram showed focal epileptiform discharges. The child's development did not progress; she began to manifest, cognitive, behavioral and language delays. Because of that, we performed an epilepsy gene panel test. We report a case of epilepsy with mental retardation limited to female patients with mutation of PCDH19.

EFMR은 뇌전증을 보이는 여자 환자에게서 지적장애가 동반된 것이 특징적인데 이들 중 PCDH19 변이와 연관이 있는 경우를 PCDH19 연관성 뇌전증으로 분류하였다. PCDH19 연관성 뇌전증은 조기에 발병하며 열에 민감하고 잘 조절되지 않는 군집발작을 보이는 것이 특징이다. 발달장애나 인지 및 행동장애를 동반할 수 있으며 정상에서부터 중증까지 다양하게 나타날 수 있다. 최근 이러한 질환에서 유전적 원인을 찾고자 하는 노력으로 뇌전증 유전자 패널을 이용하는 경우가 많아지고 있다. 저자들은 EFMR 환자에서 뇌전증 유전자 패널을 이용한 유전자 검사상 PCDH19 돌연변이가 확인된 사례를 경험하였기에 보고하는 바이다.
