Living with 14q24.1q24.3 microdeletion syndrome

A rare genetic condition that can bring mild learning challenges, delayed speech, heart differences, and short fingers.

Understanding 14q24.1q24.3 microdeletion syndrome

14q24.1q24.3 microdeletion syndrome is a rare genetic condition that includes intellectual disability.

People with this condition have mild intellectual disability and delayed speech. Heart defects present from birth, short fingers and toes (brachydactyly), and distinct facial features are also part of it. GARD lists onset as newborn.

Signs & symptoms

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

  • Mild intellectual disability
  • Heart differences (abnormal heart shape)
  • Short fingers or toes (brachydactyly)
  • Short thumb
  • Very flexible joints (joint hypermobility)
  • Wide-set eyes (hypertelorism)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

    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.
