Living with Dermo-odonto dysplasia

A rare condition affecting the skin, nails, hair, and teeth, with a wide range of severity.

Understanding Dermo-odonto dysplasia

Dermo-odonto dysplasia is a rare ectodermal dysplasia syndrome that affects the skin, nails, hair, and teeth.

Severity varies. Features include dry, thin skin, nail changes, hair changes, and tooth differences such as missing or small teeth and baby teeth that stay in. GARD lists onset in childhood and notes no further descriptions since 1990.

Signs & symptoms

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

  • Abnormal fingernail and toenail development
  • Reduced sweating
  • Small teeth (microdontia)
  • Large lower jaw (mandibular prognathism)
  • Abnormal fingerprints
  • Eyelid differences

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 genetic specialists, gum, teeth and mouth specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

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

GARD doesn't name a gene. It lists autosomal dominant inheritance, so a changed copy of the gene from one parent can be enough.
