Dyskeratosis Congenita: Causes, Symptoms, and Treatment

What kind of doctor treats Dyskeratosis Congenita?
A hematologist (a doctor who treats blood disorders) and a geneticist (a doctor who treats inherited conditions) can be part of the care team for dyskeratosis congenita. Skin, dental, and cancer doctors may join the team. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is dyskeratosis congenita?
Dyskeratosis congenita is a rare disorder that can affect many parts of the body. It has three main features. Fingernails and toenails grow poorly or have an odd shape. The skin changes color in a lacy pattern. White patches form inside the mouth.
People with it have a higher risk of problems with the bone marrow. The bone marrow is the soft tissue inside bones that makes blood cells.
Symptoms
Symptoms vary a lot from person to person. Common signs include:
- Nails that grow poorly or look odd.
- Lacy skin color changes, especially on the neck and chest.
- White patches inside the mouth, called oral leukoplakia.
Some people also have narrow tear ducts that may become blocked, dental problems, hair loss or early gray hair, low bone density, or liver disease.
Bruising, small red spots on the skin, pale skin, and frequent infections may be the first signs of bone marrow failure.
Some people develop pulmonary fibrosis, which is scar tissue in the lungs. Breathing problems and lower lung function may be signs of lung disease.
How severe it is varies widely. The mildest cases have only a few mild features and normal bone marrow function. Most people have normal intelligence.
Causes and who gets it
In about half of people, a change in the TERT, TERC, DKC1, or TINF2 gene causes the disorder. These genes help maintain telomeres. Telomeres are the caps at the ends of chromosomes. When telomeres get too short, fast-growing cells are most vulnerable. These include cells in the nail beds, hair follicles, skin, mouth lining, and bone marrow.
In other people, the cause is not known.
The disorder can be passed down in different ways. When the DKC1 gene is involved, it is X-linked recessive. Males are affected much more often than females. Other genes can pass it down in a dominant or recessive pattern. In many people, the parents do not have the disease. The gene change may be new in the child.
How doctors diagnose it
Doctors may suspect it from a full exam, a detailed health history, and typical changes in the skin or mouth. Very short telomeres in blood cells may support the diagnosis in people with bone marrow failure.
Gene tests can confirm the diagnosis. But in about half of people with classic signs, no gene change is found. A normal gene test does not always rule it out.
Treatment
Treatment is aimed at the symptoms each person has. Care may need a team of doctors. The team can include children's doctors, adult internists, blood doctors, skin doctors, dental specialists, geneticists, and cancer doctors.
General advice includes avoiding smoking and alcohol to protect the lungs and liver. Moisturizing creams can help prevent skin damage. Good dental care may help prevent early tooth loss.
In some people, bone marrow failure improves for a short time with androgens (man-made male hormones) or with growth factors that raise white blood cell counts.
A stem cell transplant is another option. If a matching donor is found, it can potentially cure the blood problems. It should be considered for people whose main problem is bone marrow failure. It does not improve other tissues affected by the disorder. Lung problems after a transplant are not rare and may be fatal.
Doctors should watch for lung disease and cancer. Genetic counseling may help affected people and their families.
When to see a doctor
Tell a doctor if you or your child has poorly formed nails, lacy skin color changes, or white patches in the mouth. These are the three features that mark this disorder. Bruising, small red spots, pale skin, or frequent infections can be early signs of bone marrow failure. Ongoing breathing problems should also be checked, because they may be signs of lung disease.
Call 911 or go to the emergency room if you have bleeding that will not stop, severe trouble breathing, chest pain lasting two minutes or more, fainting, or sudden confusion.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can review symptoms, order blood tests, and help coordinate specialists such as a blood doctor and a geneticist. They can also help keep up with follow-up visits and checks for lung disease and cancer.
Common questions
Is dyskeratosis congenita inherited?
Yes, it is usually passed down in families, but not always. In many people the parents do not have the disease, and the gene change may be new. It can follow X-linked, autosomal dominant, or autosomal recessive patterns.
Does dyskeratosis congenita affect intelligence?
Usually not. Most people with it have normal intelligence and normal motor skills, such as standing and walking. Developmental delay may happen in some severely affected people.
Does dyskeratosis congenita raise the risk of cancer?
Yes. People with it have a higher risk of leukemia and other cancers, especially of the head, neck, anus, or genitals.
Does everyone with dyskeratosis congenita get bone marrow failure?
No. The mildest cases have normal bone marrow function. Still, most people with it eventually develop bone marrow failure.
