Living with DYRK1A-related intellectual disability syndrome

A rare genetic condition with a small head, delayed development, speech and feeding difficulties, and behavior differences.

Understanding DYRK1A-related intellectual disability syndrome

DYRK1A-related intellectual disability syndrome is a rare genetic condition that affects head size, development, speech, and behavior.

People often have a smaller head, delayed development, mild to severe intellectual disability, trouble with speech and feeding, and behavior problems. Facial features can include prominent ears, deep-set eyes, and a short nose with a broad tip. Other features vary and may include seizures, short height, and eye, heart, urinary, muscle, or bone problems. Signs show up in infancy.

Signs & symptoms

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

  • Small head size (microcephaly)
  • Delayed speech and language
  • Intellectual disability
  • Seizures, including with fever
  • Feeding difficulties
  • Autistic behavior and anxiety

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 DYRK1A are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

InheritanceAutosomal Dominant
GenesDYRK1A

GARD says changes in the DYRK1A gene cause this condition. It is autosomal dominant, meaning one changed copy of the gene can cause it.
