Living with Microcephaly-cleft palate syndrome

A rare syndrome with a small head, cleft palate, and other differences that can include eye and mild learning differences.

Understanding Microcephaly-cleft palate syndrome

Microcephaly-cleft palate syndrome is a rare syndrome that includes a small head and a cleft (opening) in the roof of the mouth.

This syndrome is marked by a small head (microcephaly) and a cleft in the roof of the mouth (cleft palate). Other features can vary and may include changes in the pigment of the retina, certain facial features, goiter, and mild intellectual disability. GARD notes there have been no further descriptions in the medical literature since 1983.

Signs & symptoms

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

  • Smaller-than-average head size (microcephaly)
  • Cleft palate
  • Split uvula (bifid uvula)
  • Cleft in the bony part of the palate under the lining

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. 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.
