Living with Odontomicronychial dysplasia

A rare genetic condition affecting the teeth and nails, with teeth that come in and fall out early and short, thin nails.

Understanding Odontomicronychial dysplasia

Odontomicronychial dysplasia is a rare inherited ectodermal dysplasia that affects the teeth and nails.

Baby teeth come in early and are lost early, and adult teeth also come in early, with short, rhomboid-shaped roots. Nails are short, thin, and slow growing. GARD lists childhood as the usual onset.

Signs & symptoms

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

  • Early eruption of adult teeth
  • Early loss of baby teeth
  • Dental cavities
  • Short nails
  • Thin nails
  • Slow-growing nails

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.
