Abstract:
Objective To study the clinical characteristics of autism in febrile seizures plus (FS+) and the relationship between autism and SCN1A mutation. Methods Clinical data of 103 patients with FS+ treated in epilepsy centre of the Second Affiliated Hospital of Guangzhou Medical University were collected and analyzed. According to the international criteria, generalized epilepsy with febrile seizures plus (GEFS+), partial seizures with febrile seizures plus (PEFS+), Dravet syndrome (DS) and autism were diagnosed. Genomic DNA was obtained from blood samples. SCN1A were PCR amplified and mutations were detected by DHPLC and sequencing. Result Mental retardation was found in 53.8%of patients with GEFS+, 69.2%of patients with PEFS+, and all patients with DS, respectively. One in GEFS+, one in PEFS+and nine in DS patients were accompanied with autism (P<0.01). Among FS+patients with autism, one SCN1A mutation was found in PEFS+patients, while six SCN1A mutations were found in DS patients. Conclusions Majority of GEFS+and PEFS+patients showed mental retardation, while all the DS patients were accompanied with retardation. The occurrence of autism with DS is higher than GEFS+and PEFS+. No definite relationship between autism and SCN1A mutation was indicated.
