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.
The incidence of Parkinson's disease is found to be slightly higher in men as compared to women. Symptoms of Parkinson's disease result from the loss of dopamine secreting nerve cells in some part of the midbrain. The nerve cells in one part of the midbrain called pars compacta secrete a vital chemical called dopamine.
