Definition of Parkinson disease gene
Parkinson disease gene: A gene involved in the causation of Parkinson disease. There are a number of different autosomal dominant and recessive forms of Parkinson disease.
They are called PARK1, PARK2, and so on:
People in an Iowa family affected with an early-onset autosomal dominant form of Parkinson disease have a triplication of the alpha-synuclein gene (SNCA) on chromosome 4q21. This may be another genetic route to PARK1.
