Living with Recessive intellectual disability-motor dysfunction-multiple joint contractures syndrome

A rare genetic syndrome with severe intellectual disability, loss of motor skills, and joints that tighten over time.

Understanding Recessive intellectual disability-motor dysfunction-multiple joint contractures syndrome

Recessive intellectual disability-motor dysfunction-multiple joint contractures syndrome is a rare genetic syndrome with severe intellectual disability and worsening joint tightness.

Motor skills and speech stop developing and then regress. Joint contractures start in the lower limbs after birth and slowly move upward to the spine and neck, which leads to a fixed position. GARD lists onset in the newborn and infant period.

Signs & symptoms

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

  • Severe intellectual disability
  • Tight joints (contractures) in the legs, knees, and elbows
  • Loss of developmental skills
  • No speech development
  • Seizures with fever
  • Large tongue and wide mouth

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 ERLIN2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Recessive
GenesERLIN2

This condition is caused by changes in the ERLIN2 gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
