Living with Weiss-Kruszka syndrome

A genetic condition with a ridge on the forehead, drooping eyelids, developmental delay, and sometimes heart defects.

Understanding Weiss-Kruszka syndrome

Weiss-Kruszka syndrome is a genetic condition marked by a forehead ridge, drooping eyelids, developmental delay, and autistic features.

The forehead ridge comes from early closing of a skull seam (metopic synostosis). Brain imaging may show differences in the corpus callosum. People may also have ear differences, feeding difficulties (sometimes needing a feeding tube), and heart defects. GARD says features vary a lot, even within one family.

Signs & symptoms

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

  • Ridge on the forehead (metopic ridge)
  • Drooping upper eyelid
  • Developmental delay
  • Delayed speech and language
  • Autistic behavior
  • Feeding difficulties

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, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in ZNF462 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
