Research Abstract |
A novel missense mutation(S126L) in HCN2 was identified from febrile seizure(FS) patients. As bath temperature was raised at 38.C, V_1/2 of mutant channels shifted depolarized side and fast time constant of mutant channels accelerated compared with wild-type channels. There was no significant difference between wild-type and mutant channels about responses to cyclic AMP(cAMP). These results suggest that this mutation might alter neuronal excitability during hyperthermia.
