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.
Parkinson's disease involves decreased levels of dopamine in certain areas of the brain. PET images show differences in F-DOPA levels between a Parkinson patient's brain (right) and a control (left).he Duke researchers saw evidence of genetic linkage to five distinct regions on chromosomes 5, 6, 8, 9, and 17. Chromosome 6 contains the Parkin gene, previously thought to be involved only in the rare early-onset form of the disease.
