Living with Autosomal recessive juvenile Parkinson disease 2

An early-onset, inherited form of Parkinson disease with tremor, stiffness, and slow movement.

Understanding Autosomal recessive juvenile Parkinson disease 2

Autosomal recessive juvenile Parkinson disease 2 (PARK-Parkin) is an early-onset, inherited form of Parkinson disease.

It has the main signs of Parkinson disease: slow movement, resting tremor, and stiffness. The median age at onset is 31 years, but it can range from age 3 to 81. It is slowly progressive. Overactive reflexes are common, and leg dystonia can be a first sign. Thinking decline appears to be no more common than in the general population. Treatment with levodopa often causes extra movements (dyskinesia).

Signs & symptoms

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

  • Slow movement (bradykinesia)
  • Resting tremor, including pill-rolling tremor
  • Muscle stiffness (rigidity)
  • Balance problems
  • Shuffling walk
  • Overactive reflexes

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

    Dysautonomia International, Parkinson & Movement Disorder Alliance and Parkinson's Foundation may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Recessive

It is autosomal recessive, so a child inherits a changed copy of a gene from each parent. GARD does not name a gene here, but calls it the Parkin type.
