What kind of doctor treats Clouston Syndrome?
A primary care doctor is often the first stop and can coordinate a team that may include a dermatologist, a dentist, an ear nose and throat doctor, and an eye doctor. 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 Clouston syndrome?
Clouston syndrome is a rare condition a person is born with. It mainly affects the skin, nails, hair, teeth, and bones of the hands and feet. It is sometimes called hidrotic ectodermal dysplasia. That name means a group of conditions that affect the outer layers of the body, such as skin and hair.
Clouston syndrome belongs to a family of conditions called ectodermal dysplasia, which affects parts of the body that grow from the ectoderm: the skin, hair, nails, teeth, and sweat glands. Sweating is usually normal.
Symptoms
Signs vary from person to person. Nails are often thick, short, or oddly shaped. Hair is sparse, fine, and slow to grow. The skin on the palms and soles may become thick and hard, and some people have shorter fingers and toes, narrow or missing teeth, or hearing loss.
Causes and who gets it
Clouston syndrome is caused by a change in a gene called GJB6. It is passed down in an autosomal dominant pattern: a child needs the changed gene from only one parent, who has a one in two chance of passing it to each child.
How doctors diagnose it
Doctors start with a physical exam and health history. A genetic test using a blood or saliva sample can confirm the diagnosis by looking for the GJB6 change.
Treatment
There is no cure, so treatment focuses on managing each symptom. Thick skin on the hands and feet may be softened with creams containing urea or salicylic acid. Wigs can help with sparse hair, a dentist can replace missing teeth, and hearing aids can help with hearing loss.
When to see a doctor
Anyone with thickened nails, sparse hair, and hard skin on the palms and soles should talk to a doctor, especially if family members have similar features.
Common questions
Does Clouston syndrome affect intelligence or lifespan?
The condition mainly affects skin, hair, nails, teeth, and sometimes hearing and eyes. It is not known to shorten lifespan or affect intelligence. Most people with the syndrome live normal lives with ongoing symptom care.
Can Clouston syndrome be prevented?
Because it is a gene change present from birth, there is no way to prevent it. Families with a history of the condition can meet with a genetic counselor before or during pregnancy. This helps them learn about the chances of passing it on.
Is Clouston syndrome the same as other ectodermal dysplasias?
No. There are many types of ectodermal dysplasia, and they differ in which body parts are affected. In Clouston syndrome, sweating is usually normal. Some other types cause reduced sweating.
Will my children have it if I do?
Clouston syndrome is passed down in an autosomal dominant pattern. A parent with the condition has a one in two chance of passing it to each child. A genetic counselor can explain this in more detail for a specific family.
