Living with Isolated Pierre-Robin syndrome

A set of features from birth with a small lower jaw, a tongue placed far back, and airway blockage, often with a cleft palate.

Understanding Isolated Pierre-Robin syndrome

Isolated Pierre Robin syndrome (Pierre Robin sequence) is a set of head and face differences that occurs on its own, not as part of another syndrome.

It includes a small lower jaw (micrognathia), a tongue that sits further back than usual (glossoptosis), and blocked airways. Most people also have a cleft palate. These can cause trouble breathing and eating early in life, and some babies gain weight slowly. In some children the jaw catches up, and adults can have a normal-sized chin.

Signs & symptoms

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

  • Small lower jaw (micrognathia)
  • Tongue placed far back (glossoptosis)
  • Cleft palate
  • Blocked upper airway
  • Feeding difficulties in infancy
  • Slow weight gain (failure to thrive)

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 ear, nose, and throat specialists and genetic specialists.

  3. Consider genetic testing

    Changes in SOX9 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

    American Cleft Palate Craniofacial Association and World Craniofacial Foundation may keep lists of experts for this condition.

Changes in the SOX9 gene are listed, and GARD lists autosomal dominant inheritance. The small jaw starts a chain of events before birth that leads to the other features.
