Living with Dyskeratosis congenita

A genetic condition that affects the nails, skin color, and mouth, and can affect the bone marrow and lungs.

Understanding Dyskeratosis congenita

Dyskeratosis congenita is a genetic condition that can affect many parts of the body, especially the nails, skin, and bone marrow.

Three characteristic features are poorly formed nails, lacy changes in skin color on the neck and chest, and white patches in the mouth. People with this condition are more likely to have bone marrow problems, in which the bone marrow doesn't make enough blood cells. There is also a higher risk of certain blood disorders and cancers and of lung scarring (pulmonary fibrosis). Some people have eye, dental, or hair differences.

Signs & symptoms

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

  • Poorly formed fingernails and toenails
  • Lacy skin color changes (pigmentation)
  • Bone marrow failure
  • Dental problems and cavities
  • Excess sweating
  • Weakened immune system

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 allergy and immune system specialists, blood and bone marrow specialists, brain and nervous system specialists and cancer 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 and Immune Deficiency Foundation may keep lists of experts for this condition.
