Living with Dermotrichic syndrome

A rare genetic syndrome affecting skin, hair, and nails, with learning challenges, seizures, and bowel and bone differences.

Understanding Dermotrichic syndrome

Dermotrichic syndrome is a rare genetic ectodermal dysplasia syndrome that affects the skin, hair, and nails.

It causes thick, scaly skin (ichthyosis), no hair from birth, and curved nails. It also involves reduced sweating, intellectual disability, seizures, short stature, and bowel differences such as a colon missing nerve cells. Facial features can include a prominent forehead and large ears. GARD lists onset in the newborn period.

Signs & symptoms

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

  • Thick, scaly skin (ichthyosis)
  • Reduced sweating (hypohidrosis)
  • Intellectual disability
  • Enlarged colon lacking nerve cells (aganglionic megacolon)
  • Curved toenails
  • Differences in the spine bones

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 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.
