Living with Frontonasal dysplasia

A condition in which the head and face develop differently before birth, often with wide-set eyes and a broad or split nose.

Understanding Frontonasal dysplasia

Frontonasal dysplasia is a condition caused by abnormal development of the head and face before birth.

People have at least two features such as widely spaced eyes, a broad nose, a split in the nose, no nasal tip, a central cleft in the nose, lip or palate, or a widow's peak hairline. Other features may include differences in the brain's corpus callosum and intellectual disability. There are at least three types, with the most severe facial differences in type 3.

Signs & symptoms

GARD doesn't list a separate symptom list. Its summary describes:

  • Wide-set eyes (hypertelorism)
  • Broad or split nose
  • Cleft in the nose, lip or palate
  • Widow's peak hairline
  • Incomplete formation of the front of the skull
  • Intellectual disability in some people

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 and genetic specialists.

  3. Ask which tests can help

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