Living with Dyskeratosis congenita, autosomal recessive 1

An inherited telomere-related condition that can affect the skin, nails, mouth, bone marrow, lungs, eyes, and teeth.

Understanding Dyskeratosis congenita, autosomal recessive 1

Dyskeratosis congenita, autosomal recessive 1, is a rare inherited condition that affects how the body maintains telomeres, the caps on the ends of chromosomes.

It can involve the skin, nails, mouth, bone marrow, lungs, eyes, and teeth. A classic combination is abnormal nails, lace-like darker skin on the upper chest or neck, and white patches in the mouth, though not everyone has all three. There is a higher risk of bone marrow failure, certain blood cancers, solid tumors, and lung scarring. Severity ranges widely.

Signs & symptoms

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

  • Bone marrow failure or aplastic anemia
  • Low blood cell counts (pancytopenia)
  • Poorly formed nails
  • Lacy darker skin (reticular hyperpigmentation)
  • Thick skin on the palms and soles
  • Watery eyes or blocked tear ducts

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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

Quick facts

InheritanceAutosomal Recessive

GARD says it is an autosomal recessive condition, meaning a child inherits a changed copy of the gene from each parent. It affects how the body maintains telomeres.
