Living with Ritscher-Schinzel syndrome

A rare syndrome present from birth that affects the head and face, the back of the brain (cerebellum), and the heart.

Understanding Ritscher-Schinzel syndrome

Ritscher-Schinzel syndrome, also called cranio-cerebello-cardiac (3C) syndrome, is a rare syndrome with differences in the head and face, brain, and heart.

Head and face features include a prominent forehead, wide-set eyes, an eye gap (coloboma), and cleft palate. Brain features involve the cerebellum, such as a Dandy-Walker malformation. Heart features include holes between heart chambers and tetralogy of Fallot. It can be noticed during pregnancy, at birth, or in infancy.

Signs & symptoms

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

  • Heart differences, such as holes between chambers
  • Small or missing cerebellum
  • Dandy-Walker malformation
  • Cleft palate
  • Global developmental delay
  • Intellectual disability

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 and genetic specialists.

  3. Ask which tests can help

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