Living with Congenital muscular dystrophy with intellectual disability and severe epilepsy

A rare genetic condition with weak muscles, severe developmental delay, and seizures starting in infancy.

Understanding Congenital muscular dystrophy with intellectual disability and severe epilepsy

Congenital muscular dystrophy with intellectual disability and severe epilepsy is a rare inherited metabolic condition that affects muscles and the brain.

Babies have breathing trouble and very low muscle tone at birth, severe developmental delay, and seizures that start early and are hard to control. Facial features can differ, and joints are stiff and bent from birth. Scoliosis, optic nerve changes, a mildly enlarged liver, and underdeveloped genitals may also occur.

Signs & symptoms

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

  • Seizures
  • Low muscle tone (hypotonia)
  • Global developmental delay
  • Tight joints (contractures)
  • Poor weight gain (failure to thrive)
  • Scoliosis

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, digestive system specialists, genetic specialists and seizure and epilepsy specialists.

  3. Consider genetic testing

    Changes in DPM2 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

    CDG CARE and Epilepsy Foundation may keep lists of experts for this condition.

InheritanceAutosomal Recessive
GenesDPM2

It is caused by changes in the DPM2 gene. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
