Living with Skraban-Deardorff syndrome

A rare genetic condition present from birth with developmental delay, learning challenges, seizures and walking problems.

Understanding Skraban-Deardorff syndrome

Skraban-Deardorff syndrome is a rare genetic condition present at birth that causes global developmental delay and intellectual disability.

Symptoms can include seizures and walking problems. People may have distinctive facial features, such as a flat nose, a wide mouth and widely spaced teeth. Some have eye, heart or stomach problems, or features of autism. Brain imaging can show a thinner corpus callosum and other differences. It starts in infancy.

Signs & symptoms

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

  • Intellectual disability
  • Delayed speech and language
  • Delayed sitting and walking
  • Seizures
  • Feeding difficulties in infancy
  • Distinctive facial features

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 WDR26 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
