Living with Exostoses-anetodermia-brachydactyly type E syndrome

A very rare inherited condition with bony growths, patches of thin skin, and short fingers or toes.

Understanding Exostoses-anetodermia-brachydactyly type E syndrome

Exostoses-anetodermia-brachydactyly type E syndrome is a very rare condition that was reported in a single family.

It is seen in newborns. It involves anetodermia (patches of thin, wasted skin), multiple exostoses (bony growths), and brachydactyly type E (short fingers or toes). The features vary from person to person.

Signs & symptoms

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

  • Multiple bony growths (exostoses)
  • Patches of thin skin (anetodermia)
  • Short fingers or toes (brachydactyly type E)
  • Flat, discolored patches of skin

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 and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
