Living with Lethal congenital contracture syndrome 11

A rare inherited condition with joint contractures, small lungs, and a small jaw present at birth.

Understanding Lethal congenital contracture syndrome 11

Lethal congenital contracture syndrome 11 (LCCS11) is a rare inherited condition marked by joint contractures present at birth.

A contracture means a joint is permanently fixed in a bent or straight position. It has been described in only a few people. Features include contractures in the arms and legs, very small lungs, a small recessed lower jaw, bent fingers and toes, and clubfoot on both sides. Ultrasound before birth may show a baby who does not move.

Signs & symptoms

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

  • Bent fingers (flexion contracture)
  • Extra amniotic fluid (polyhydramnios)
  • Reduced fetal movement
  • Small lungs (pulmonary hypoplasia)
  • Clubfoot on both sides
  • Small, recessed lower jaw (retrognathia)

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
