Living with EEM syndrome

A rare inherited condition with missing teeth, sparse hair, split hands or feet, and a retinal problem in the center of the eye.

Understanding EEM syndrome

EEM syndrome is a rare ectodermal dysplasia that combines hair and tooth differences, split hands or feet (ectrodactyly), and macular dystrophy.

People have thin scalp hair, eyebrows, and eyelashes, and partly missing teeth. They have ectrodactyly and macular dystrophy, a problem in the center of the retina that can affect vision. Other limb differences include extra, joined, or bent fingers. The hands are often more affected than the feet. It is present from the newborn period.

Signs & symptoms

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

  • Sparse scalp hair, body hair, and missing eyebrows
  • Missing or small teeth
  • Split hand or foot (ectrodactyly)
  • Macular dystrophy (central retina damage)
  • Vision problems
  • Joined fingers (syndactyly)

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 bone and joint specialists, eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in CDH3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.

GenesCDH3

GARD says changes in the CDH3 gene cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
