Gene for common form of Parkinson's pinpointed
Researchers have identified a new
gene that causes a common form of inherited Parkinson's disease (PD) and whose understanding they believe "will impact not only patients and their families but will open novel avenues of research aimed at identifying and ultimately halting the molecu...
