Living with Gabriele de Vries syndrome

A genetic condition present at birth that can affect development, movement, facial features, and sometimes the eyes, heart, kidneys, and joints.

Understanding Gabriele de Vries syndrome

Gabriele-de Vries syndrome is a rare genetic condition present from birth that affects development and learning.

People with this syndrome may have delays in development and intellectual disability, and problems with movement and walking. Some have distinct facial features, such as a broad forehead or a small lower jaw. Some also have eye, kidney, heart, or joint problems, or behavioral differences such as autism, hyperactivity, or anxiety.

Signs & symptoms

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

  • Delays in overall development
  • Delayed speech and language
  • Delayed walking
  • Low muscle tone (hypotonia)
  • Feeding difficulties in infancy
  • Facial differences, such as a broad forehead or uneven face

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. Consider genetic testing

    Changes in YY1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
