Living with Juvenile onset Parkinson disease 19A

A rare genetic brain and nerve condition with Parkinson-like stiffness, slow movement, and tremor starting in childhood or the teens.

Understanding Juvenile onset Parkinson disease 19A

Juvenile-onset Parkinson disease 19A is a rare genetic disorder that causes parkinsonism in the first or second decade of life.

Parkinsonism means symptoms like stiffness, slow movement, and tremors. Some people also have developmental delay, intellectual disability, mood disorders, or seizures.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Slow movements (bradykinesia)
  • Stiffness (rigidity)
  • Pill-rolling tremor
  • Balance problems
  • Trouble speaking clearly (dysarthria)
  • Reduced facial expression

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    American Parkinson Disease Association, Parkinson & Movement Disorder Alliance and Parkinson's Foundation may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Recessive

Changes in the DNAJC6 gene cause this condition. It is autosomal recessive, meaning two changed copies of the gene, one from each parent, are needed to cause the disease.

Also known as: dnajc6 parkinson disease; juvenile onset parkinson disease type 19a; park19; parkinson disease caused by mutation in dnajc6
