Living with Lethal congenital contracture syndrome 1

A rare inherited condition with absent movement before birth, many joint contractures, and small lungs.

Understanding Lethal congenital contracture syndrome 1

Lethal congenital contracture syndrome 1 is a rare inherited condition in which a baby does not move before birth and has multiple stiff joints.

Lack of movement (fetal akinesia) can be detected as early as the 13th week of pregnancy. It comes with extra fluid, a small lower jaw, small lungs, skin webs, and joint contractures. Nerve cells that control muscles are lacking in the spinal cord, and muscles are small.

Signs & symptoms

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

  • Limited joint movement
  • Small lungs (pulmonary hypoplasia)
  • Small lower jaw (micrognathia)
  • Extra amniotic fluid (polyhydramnios)
  • Short or webbed neck
  • Muscle wasting

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 bone and joint specialists, genetic specialists and lung and breathing specialists.

  3. Consider genetic testing

    Changes in GLE1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
