Objective
To evaluate the clinical efficacy and safety of quinidine in patients with KCNT1‐related epilepsy of infancy with migrating focal seizures (EIMFS) in the infantile period and to compare with the effect of quinidine on mutant channels in vitro.
Methods
We identified 4 patients with EIMFS with onset in the neonatal period, pathogenic variants in the KCNT1 gene, and lack of response to AEDs...
ObjectiveFracture risk is a serious comorbidity in epilepsy and may relate to the use of antiepileptic drugs (AEDs). Many AEDs inhibit ion channel function, and the expression of these channels in osteoblasts raises the question of whether altered bone signaling increases bone fragility. We aimed to confirm the expression of voltage‐gated sodium (NaV) channels in mouse osteoblasts, and to investigate...
Childhood absence epilepsy (CAE) is one of the most common forms of epilepsy among children. The study of a large Australian family demonstrated that a point mutation in the gene encoding the gamma2 subunit of the GABA(A) receptor (G2R43Q) leads to an autosomal dominantly inherited form of CAE and febrile seizures (FS). In a transgenic mouse model carrying the gamma2 (R43Q) mutation heterozygous animals...
The purinergic rP2X7 receptor expressed in a number of heterologous systems not only functions as a cation channel but also gives rise to a P2Z-like response, i.e. a reversible membrane permeabilization that allows the passage of molecules with molecular masses of ≥300 Da. We investigated the properties of rP2X7 receptors expressed in Xenopus oocytes. In two-electrode voltage-clamp experiments, ATP...
