Scientists shed new light on cause of inherited movement disorder

University of Utah School of Medicine researchers and their colleagues at University of Texas Southwestern Medical Center have found strong evidence that abnormal calcium signaling in neurons may play an important role in the development of spinocerebellar ataxia type 2 (SCA2), a disorder causing progressive loss of coordination, speech difficulty and abnormal eye movements. Their findings are published in the July 27, 2009, issue of Journal of Neuroscience.
