Living with Schuurs-Hoeijmakers syndrome

A genetic condition, also called PACS1 syndrome, with intellectual disability, speech and language problems, and a distinct facial appearance.

Understanding Schuurs-Hoeijmakers syndrome

Schuurs-Hoeijmakers syndrome, also called PACS1 syndrome, is a genetic condition with intellectual disability and speech and language problems.

Everyone with this condition has intellectual disability (mild to moderate), speech and language problems, and a distinct facial appearance. Speech ranges from limited to none. Many people have other neurological, behavior, or health problems, such as autism features, feeding difficulties, or reflux. It begins during pregnancy, at birth, or in infancy.

Signs & symptoms

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

  • Intellectual disability
  • Delayed speech and language
  • Global developmental delay
  • Low muscle tone in infancy
  • Seizures
  • Feeding difficulties, including trouble with solid foods

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 PACS1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
