Living with Ectrodactyly-ectodermal dysplasia-clefting syndrome

A rare condition with missing or split fingers and toes, hair and gland differences, and cleft lip or palate.

Understanding Ectrodactyly-ectodermal dysplasia-clefting syndrome

EEC syndrome (Ectrodactyly-Ectodermal Dysplasia-Cleft lip/palate) is a rare form of ectodermal dysplasia.

Symptoms range from mild to severe. The most common are missing or irregular fingers and toes (split hand/foot), hair and gland differences, cleft lip or palate, distinctive facial features, and eye and urinary tract differences. More than 90 percent of people have type 3, caused by changes in the TP63 gene. Signs begin during pregnancy or at birth.

Signs & symptoms

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

  • Split hand or foot (ectrodactyly)
  • Cleft lip or palate
  • Fewer or small teeth with weak enamel
  • Tear duct and eye problems
  • Dry skin and coarse hair
  • Small or missing kidney

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, ear, nose, and throat specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in TP63 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 and World Craniofacial Foundation may keep lists of experts for this condition.

Quick facts

Symptoms usually startduring Pregnancy and as a Newborn
InheritanceAutosomal Dominant
GenesTP63

GARD says changes in the TP63 gene cause most cases (type 3), and a region on chromosome 7 is linked to type 1. It is autosomal dominant, meaning one changed copy of the gene can cause it.
