â¢Parkinson disease 11 (PARK11): Type 11 Parkinson disease is linked to a genetic mutation on chromosome 2q21.2. Parkinson's disease is a chronic, progressive, degenerative brain disorder characterized by tremors, muscle rigidity and slowed movements.
However, the vast majority of people with Parkinson's disease do not have one of these identified genetic abnormalities. It is probable that in people who develop Parkinson's disease early in life (called young-onset Parkinson's disease) there is a genetic component. Because we don't understand very much at this point about how Parkinson's disease is inherited, the implications for children of people with Parkinson's disease are unclear.
