Living with Barber-Say syndrome

A very rare condition with extra hair growth, thin fragile skin, outward-turned eyelids, and a large mouth.

Understanding Barber-Say syndrome

Barber-Say syndrome is a very rare condition with excess hair growth, thin and fragile skin, outward-turned eyelids, and a large mouth.

It is present from birth and varies from mild to severe. Other features can include missing eyebrows and eyelashes, a wide nasal bridge, late tooth eruption, and hearing loss.

Signs & symptoms

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

  • Extra hair growth over the body
  • Eyelids that turn outward (ectropion)
  • Thin, loose skin
  • Wide mouth
  • Sparse or absent eyebrows and eyelashes
  • Hearing loss

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 eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in TWIST2 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

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.
