چکیده

TBC1D24 mutation-related epileptic syndrome includes a wide spectrum of epilepsies. We describe a case with a homozygous TBC1D24 mutation inherited from consanguineous parents. The patient manifested epilepsia partialis continua (EPC) and rare secondary generalized tonic-clonic seizure without intellectual disability or developmental delay. EPC, which involved focal limbs, came with waking and went with sleep. The genetic analysis reported a novel mutation in the TBC1D24 gene, c.229_240del (p.82_84del). The homozygous mutation was inherited from her healthy parents who were heterozygous. Morphometric analysis program (MAP), an MRI post-processing technique, was used and detected a subtle abnormality of the brain. A comprehensive analysis based on semiology, electroencephalogram, somatosensory-evoked potential, and MAP suggested a potential focal structural abnormality. This case indicates a possible correlation between the TBC1D24 mutation and brain development abnormality.

Alternating Hemiplegia and Epilepsia Partialis Continua: A new phenotype for a novel compound TBC1D24 mutation

Mutations in the TBC1D24 gene (MIM 613577) cause familial infantile myoclonic epilepsy (FIME; 605021) and early infantile epileptic encephalopathy-16 (EIEE16; 615338), both inherited with an autosomal recessive trait. The TBC1D24 gene encodes a member of the TBC family domain proteins, involved in cell signaling and oxidative stress resistance. We studied, by a Next Generation Sequencing (NGS) ...

Seizure freedom in epilepsia partialis continua (EPC) through vagus nerve stimulation (VNS) therapy: A case report☆

Vagus nerve stimulation (VNS) is generally considered as a palliative treatment for patients with drug-resistant partial-onset epilepsy. We report a case in which a patient with drug-resistant epilepsia partialis continua (EPC), became seizure-free for 15 months with VNS combined with antiepileptic medication regimens. To our knowledge, similar cases have not been reported previously.
