Living with Pai syndrome

A rare condition with a split in the middle of the upper lip, skin and nose growths, and wide-set eyes.

Understanding Pai syndrome

Pai syndrome is a rare condition affecting the middle of the face, noticed before or soon after birth.

It involves a split in the middle of the upper lip, small growths (polyps) on the skin and inside the nose, and fatty growths (lipomas) in the brain. Wide-set eyes and other eye differences are also seen. Development and thinking skills are generally normal.

Signs & symptoms

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

  • Split in the middle of the upper lip
  • Cleft palate or split uvula
  • Wide-set eyes (hypertelorism)
  • Flat nasal bridge
  • Growths in the nose (nasal polyps) or skin tags
  • Fatty growths in the brain's midline

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, ear, nose, and throat specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

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

Everyday life

Living with a rare condition is easier with support.

  • Connect with World Craniofacial Foundation and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
What kind of surgery or care could help with the lip and palate?
Should we have a brain scan to look for the fatty growths (lipomas)?
Would genetic testing help us understand the chance of passing this on?
