Living with Isolated cleft palate

A condition present from birth in which the roof of the mouth has an opening because the two sides did not join during development.

Understanding Isolated cleft palate

Isolated cleft palate is a condition present from birth in which there is an opening along the middle of the roof of the mouth.

The opening can involve the hard palate, the soft palate, or both. It happens when the two sides of the palate fail to join during early development in the womb. "Isolated" means it occurs without other conditions.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Its summary describes this main feature:

  • Opening in the roof of the mouth (hard and/or soft palate)

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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