Living with Dystonia 16

A genetic movement disorder with muscle tightening and twisting that usually begins in childhood and slowly spreads.

Understanding Dystonia 16

Dystonia 16 is a form of dystonia that causes involuntary movements, twisting, and tensing of muscles.

It can start at any age but most often begins in childhood. It usually affects an arm or leg first, or neck muscles. The jaw, lips, tongue, and voice muscles are commonly affected, causing trouble with swallowing and speech. It slowly gets worse and spreads. Some people develop mild parkinsonism. GARD says symptoms usually do not improve with typical movement disorder medicines.

Signs & symptoms

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

  • Muscle tightening in the limbs (limb dystonia)
  • Wry neck (torticollis)
  • Trouble speaking (dysarthria) or using the voice
  • Trouble swallowing (dysphagia)
  • Slow movements and tremor (parkinsonism)
  • Unsteady walk

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

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in PRKRA are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Dystonia Medical Research Foundation and Parkinson & Movement Disorder Alliance may keep lists of experts for this condition.

GenesPRKRA

GARD says changes in the PRKRA gene cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
