Living with Congenital hereditary facial paralysis-variable hearing loss syndrome

An extremely rare inherited condition with weak face muscles on both sides, hearing loss and eyes that do not line up.

Understanding Congenital hereditary facial paralysis-variable hearing loss syndrome

Congenital hereditary facial paralysis-variable hearing loss syndrome is an extremely rare inherited condition that affects facial movement and hearing.

People have facial palsy on both sides, which gives the face a mask-like look. They also have hearing loss from inner ear or nerve problems, eyes that do not line up (strabismus), and facial differences such as a flat midface and low-set ears. It is seen in newborns and infants.

Signs & symptoms

GARD doesn't list a separate symptom list for this condition. The summary describes:

  • Facial palsy on both sides with a mask-like face
  • Hearing loss (sensorineural)
  • Eyes that do not line up (strabismus)
  • Flat midface
  • Low-set ears

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

  3. Consider genetic testing

    Changes in HOXB1 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.
