Living with Brachydactyly-mesomelia-intellectual disability-heart defects syndrome

A rare genetic syndrome with short fingers, short forearms, learning delays, and heart differences.

Understanding Brachydactyly-mesomelia-intellectual disability-heart defects syndrome

Brachydactyly-mesomelia-intellectual disability-heart defects syndrome is a rare genetic syndrome with developmental delay, short fingers, short middle limb segments, and heart differences.

It is noticed at birth. People often have a thin build with narrow shoulders and distinct facial features, including a long lower face, beaked nose, and high-arched palate. Heart differences include a widened aortic root and a mitral valve that does not close well (prolapse).

Signs & symptoms

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

  • Developmental delay and intellectual disability
  • Short fingers or toes (brachydactyly)
  • Short forearms and lower legs (mesomelia)
  • Heart valve differences
  • Beaked nose and small lower jaw
  • Missing teeth

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.
