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.
1 Identified a variant in a gene (VPS35) that is the latest gene identified to cause Parkinson's disease. 2  Discovered mutations in a gene (DCTN1) that produce a very severe form of parkinsonism associated with breathing difficulties and severe depression.ogether, Mayo physicians and researchers have discovered a number of genes that cause parkinsonian disorders. For example, Mayo researchers: 1  Found the gene leucine-rich repeat kinase 2 (LRRK2) to be the most common genetic cause of late-onset, autosomal dominant Parkinson's disease.
