| Outline of Final Research Achievements |
Novel HCN2 mutation (S126L) found in Febrile Seizure patients was transfected to iPS cells and cultured neurons. The function of HCN mutant protein was examined by using the patch clamp method. The conductance in rat CA1 neurons transfected mutant HCN2 was increased and the distribution of the channel protein showed migration to the cell membrane in PC12 cells. These results of the neuronal cells' experiment was similar to that of the cultured cells' experiment.
These results suggest that animals with this HCN2 mutation might have the possibility of causing Febrile Seizure. And these results might help to elucidate the mechanism of Febrile Seizure.
