Netherton Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Netherton Syndrome?
A dermatologist, a doctor who treats skin and hair problems, usually leads care for Netherton syndrome. A medical geneticist, a doctor who treats inherited conditions, can help with gene testing and family planning. 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 Netherton syndrome?
Netherton syndrome is a rare genetic disorder that affects the skin, hair, and immune system. It belongs to a group of skin diseases called ichthyoses, which cause scaling of the skin. The skin barrier does not work well, which can raise the risk of infection. It is estimated to affect 1 in 200,000 newborns. Other names include Comel-Netherton syndrome and bamboo hair syndrome.
Symptoms appear at birth and can be severe and life-threatening. They tend to improve in adulthood.
Symptoms
Netherton syndrome has three typical findings: a skin condition with red, ring-shaped scaly patches, fragile hair, and a tendency to allergies. Other problems include:
- Widespread red, scaly skin at birth or within the first few weeks. Some babies are born with a tight, clear covering on the skin, which is usually shed in the first few weeks.
- Hair that is fragile and breaks easily. Some strands are thicker in some spots and thinner in others, which is called bamboo hair. Eyelashes and eyebrows can be affected.
- Allergies, such as food allergies and hay fever, along with asthma and eczema.
- Itchy skin. Scratching can lead to frequent infections.
- Dead skin cells that build up in the ear canals. This can affect hearing if the cells are not removed regularly.
- Trouble keeping a steady body temperature.
- Slow growth, short height, or low weight.
Newborns are at risk of becoming dehydrated and developing infections in the skin or throughout the body (sepsis), which can be life-threatening. The health of older children and adults usually improves.
Causes and who gets it
Netherton syndrome is caused by changes in the SPINK5 gene. This gene makes a protein that acts like a brake on enzymes in the skin. Without it, the outer layer of the skin sheds too much and becomes too thin and easy to break down. This also leads to hair problems and to allergies, asthma, and eczema.
The condition is inherited in an autosomal recessive pattern. This means a child gets a changed gene from each parent. The parents each carry one changed copy but typically show no signs of the condition. When both parents are carriers, each pregnancy has a 25% chance of an affected child.
How doctors diagnose it
A doctor may suspect Netherton syndrome from allergies plus at least one typical finding, such as the ring-shaped skin patches or the fragile hair. Netherton syndrome should be suspected in any infant with red skin all over. Genetic testing that shows changes in the SPINK5 gene is needed to confirm the diagnosis. A doctor can look at hair under a microscope for the bamboo hair change. A skin sample may also help in unclear cases. Testing before birth is available for families with a history of the disease.
Treatment
NORD reports that no specific treatment is approved for this disease in particular. Many options can ease symptoms. Treatment depends on age and symptoms.
- Infants with all-over red skin should be monitored in the hospital and treated for dehydration, infection, and poor nutrition if these occur.
- Children and adults use moisturizing creams and lotions several times a day, especially after bathing, to protect the skin barrier.
- Antibiotics may be prescribed if the skin becomes infected. Antihistamines can help control itching.
- Other options include light therapy and biologics, which are medicines that target the immune system. Response to biologics is unpredictable.
- Regular skin exams check for warts and skin cancer.
- Genetic counseling is recommended for affected people and their families.
The skin absorbs ingredients easily, so creams and ointments should be used with caution, especially in infants and children. Follow your doctor's instructions.
When to see a doctor
A baby with red, scaly skin all over should be seen by a doctor right away. See a doctor if the skin looks infected or itching is hard to control. Call 911 or go to the emergency room if a child has trouble breathing, swelling of the face, eyes, or tongue, a seizure, fever followed by a change in mental status or a stiff neck, or unusual sleepiness.
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. Such a doctor can look at new skin or hair changes, review the family history, and arrange a referral to a dermatologist or geneticist.
Common questions
Is Netherton syndrome life-threatening?
It can be, especially in newborns. Symptoms appear at birth and can be severe and life-threatening, but they tend to improve in adulthood.
Is there a treatment approved for Netherton syndrome?
No, NORD reports that no specific treatment is approved for the disease in particular. Many options exist for easing symptoms and targeting the immune system.
How is Netherton syndrome inherited?
It is passed down when both parents carry a changed SPINK5 gene. This is called autosomal recessive inheritance. The parents typically show no signs of the condition.
Does Netherton syndrome affect the hair?
Yes, it makes the hair fragile so that it breaks easily. Some strands vary in thickness, which is called bamboo hair. The eyelashes and eyebrows may also be affected.
