Annual Meeting of the Japanese Society of Neurology

Among the hereditary neurodegenerative diseases in past decades, an expansion of the number of triplet repeat sequences has been identified as a causative mutation. However, very recently, an expansion of a number of Penta- and hexa-repeat related diseases have been identified in spinocerebellar ataxia, ALS, and epilepsy. In this symposium, we invited pioneers of these findings. The audience will be able to touch on the forefront of the molecular pathogenesis of new mechanism of neurological disorders.
