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.
About 15% to 25% of Parkinson's patients have a family member with the disease, the Parkinson's Disease Foundation says. In some cases, researchers have identified a single gene mutation that's passed from generation to generation, according to the Michael J. Fox Foundation.
