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.
In families with late-onset Parkinson's, the strongest overall evidence for linkage was on chromosome 17, near the tau gene, which has been implicated in other degenerative neurological diseases, such as Alzheimer's disease.Previously, tau has not been thought to be involved in the most common form of Parkinson's.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.
