Living with Rolandic epilepsy-paroxysmal exercise-induced dystonia-writer's cramp syndrome

A rare genetic epilepsy syndrome with childhood seizures that fade with age and exercise-related muscle cramping that may last into adulthood.

Understanding Rolandic epilepsy-paroxysmal exercise-induced dystonia-writer's cramp syndrome

Rolandic epilepsy-paroxysmal exercise-induced dystonia-writer's cramp syndrome is a rare genetic epilepsy syndrome.

It starts with seizures in infancy or childhood that affect one part of the body and fade with age. In childhood, exercise-triggered dystonia (muscle contractions causing twisting or odd postures) begins and often lasts into adulthood. Other reported features include rapid eye movements (nystagmus) and hand tremor.

Signs & symptoms

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

  • Seizures that affect one side of the face
  • Exercise-triggered dystonia
  • Writer's cramp
  • Involuntary side-to-side eye movements (nystagmus)
  • Hand tremor with posture

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, genetic specialists and seizure and epilepsy specialists.

  3. Consider genetic testing

    Changes in TBC1D24 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

    Epilepsy Foundation may keep lists of experts for this condition.

Quick facts

Symptoms usually startInfant
InheritanceAutosomal Recessive
GenesTBC1D24

It is caused by changes in the TBC1D24 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
