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 most cases, an affected person has one parent with the condition. If the PARK2, PARK7, or PINK1 gene is involved, Parkinson disease is inherited in an autosomal recessive pattern. This type of inheritance means that two copies of the gene in each cell are altered.Most often, the parents of an individual with autosomal recessive Parkinson disease each carry one copy of the altered gene but do not show signs and symptoms of the disorder.When genetic alterations modify the risk of developing Parkinson disease, the inheritance pattern is usually unknown.ther characteristic symptoms of Parkinson disease include rigidity or stiffness of the limbs and torso, slow movement (bradykinesia) or an inability to move (akinesia), and impaired balance and coordination (postural instability).
