Living with 8q24.3 microdeletion syndrome

A genetic condition that can bring feeding problems, slow growth, developmental delay, and differences in the heart, kidneys, and bones.

Understanding 8q24.3 microdeletion syndrome

8q24.3 microdeletion syndrome is a genetic condition with multiple birth differences and intellectual disability.

It brings feeding problems, slow growth, a smaller head, developmental delay, and finger and spine differences. Joints may be loose or dislocate. Heart and kidney differences and distinct facial features are common. Some people have sleep apnea, repeated pneumonia, or seizures. GARD lists onset as during pregnancy and as a newborn.

Signs & symptoms

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

  • Global developmental delay
  • Feeding difficulties in infancy
  • Expressive language delay
  • Heart differences
  • Very flexible joints
  • Reduced visual sharpness

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, genetic specialists and heart and blood vessel specialists.

  3. Consider genetic testing

    Changes in PUF60 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
