Living with MEND syndrome

A rare X-linked condition in males with skin changes, severe nervous system effects, and facial differences.

Understanding MEND syndrome

MEND syndrome is a rare genetic condition that affects males and involves the skin, the nervous system, and facial features.

Skin changes include a tight, shiny membrane at birth (collodion membrane), thick scaly skin (ichthyosis), and light patches. Nervous system effects include intellectual disability, delays, and seizures. Facial differences may include a cleft palate and a small jaw. Other differences can affect the toes, fingers, heart, eyes, and urinary system. It starts in newborns and infants.

Signs & symptoms

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

  • Thick, scaly skin (ichthyosis)
  • Intellectual disability
  • Developmental delay
  • Low muscle tone
  • Small eyes and cataracts
  • Poor weight gain

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