Living with Rubinstein-Taybi syndrome

A genetic condition with short height, intellectual disability, distinct facial features, and broad thumbs and big toes.

Understanding Rubinstein-Taybi syndrome

Rubinstein-Taybi syndrome is a genetic condition with short stature, intellectual disability, distinct facial features, and broad thumbs and first toes.

Moderate to severe intellectual disability is typical. Other features can include eye differences, heart and kidney defects, dental problems, and obesity. These vary between people. GARD notes an increased risk of certain noncancerous brain and skin tumors. It begins during pregnancy or in the newborn period.

Signs & symptoms

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

  • Broad thumbs and big toes
  • Small head size (microcephaly)
  • Beaked nose
  • Heart and urinary tract differences
  • Attention and behavior differences
  • Blocked tear ducts

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, brain and nervous system specialists, cancer specialists and eye disease specialists.

  3. Ask which tests can help

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