Scientists find a role for Parkinson’s gene in the brain

NIH-funded mouse study suggests LRRK gene is needed for dopamine neuron health. A new study published in the journal Neuron sheds light on the normal function of LRRK2, the most common genetic cause for late-onset Parkinson’s disease. The study was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
