For example, we found that Kv3.2 subunit of Kv3 potassium channels (high frequency channels implicated in epilepsy, Alzheimer’s and spinocerebellar ataxia16–18) displays a pattern of developmental expression which diverges from the other three subunits (namely Kv3.1, Kv3.3 and Kv3.4). Here, KCNC4 is linked to epilepsy.
