Living with Orofacial-digital syndrome IV

A rare inherited condition affecting the mouth, face, and fingers and toes, with severe clubfoot and shortened lower legs.

Understanding Orofacial-digital syndrome IV

Orofaciodigital syndrome 4 is a rare inherited condition that affects the development of the mouth and teeth, face, and fingers and toes.

Features vary but often include benign tongue growths (hamartomas), extra fingers or toes, severe clubfoot, and short, bowed lower legs. GARD lists onset as during pregnancy, at birth, and as an infant.

Signs & symptoms

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

  • Tongue differences
  • Cleft lip or cleft palate
  • Small head (microcephaly)
  • Small or missing shin bone
  • Bulging eyes
  • Blocked back of the nose (choanal atresia)

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 TCTN3 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.
