Living with Catel-Manzke syndrome

A rare bone condition with unusual index fingers and a jaw and palate pattern called Pierre Robin sequence.

Understanding Catel-Manzke syndrome

Catel-Manzke syndrome is a rare bone disease with extra bone in the index fingers and a bent index finger, usually with Pierre Robin sequence.

Pierre Robin sequence includes a small lower jaw (micrognathia), a cleft palate, and a tongue that falls back in the throat (glossoptosis). It begins during pregnancy or at birth.

Signs & symptoms

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

  • Cleft palate
  • Small lower jaw (micrognathia)
  • Bent index fingers (clinodactyly)
  • Poor weight gain (failure to thrive)
  • Repeated middle ear infections
  • Ears turned toward the back of the head

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, brain and nervous system specialists, ear, nose, and throat specialists and genetic specialists.

  3. Consider genetic testing

    Changes in TGDS 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

    World Craniofacial Foundation may keep lists of experts for this condition.
