Waardenburg Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Waardenburg Syndrome?
A geneticist, a doctor who treats inherited conditions, often leads care for Waardenburg syndrome. You may also see a hearing specialist, an ophthalmologist (eye doctor), or a dermatologist (skin doctor), depending on your symptoms. 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 Waardenburg syndrome?
Waardenburg syndrome is a group of genetic conditions. It can cause hearing loss and changes in the color of the hair, skin, and eyes. Most people with it have normal hearing, but moderate to profound hearing loss can happen in one or both ears. An estimated 1 in 40,000 people have it.
There are four recognized types. Types I and II are the most common, and types III and IV are rare. People with type III also have differences in the arms and hands. Type IV comes with Hirschsprung disease, an intestinal disorder that causes severe constipation or blockage of the intestine.
Symptoms
Symptoms can differ a lot, even in the same family. Some people have only one feature, such as hearing loss or a change in eye color. Common signs include:
- Hearing loss that is present from birth, in one or both ears.
- Very pale blue eyes, or eyes of two different colors, such as one blue eye and one brown eye.
- A patch of white hair, or hair that turns gray early.
- Patchy, light-colored skin.
- Eyes that look wide apart, which almost always happens in type I.
- In type IV, belly bloating, vomiting, loss of appetite, and slow weight gain from Hirschsprung disease.
Hearing loss can slow speech and language growth in children.
Causes and who gets it
Changes in genes called EDN3, EDNRB, MITF, PAX3, SNAI2, and SOX10 can cause Waardenburg syndrome. These genes help build pigment cells called melanocytes. Melanin, the pigment they make, gives color to skin, hair, and eyes and helps the inner ear work.
It is usually inherited in an autosomal dominant pattern, which means one changed copy of the gene is enough to cause it. In most cases, an affected person has one parent with the condition. An affected parent has a 50% chance of passing it to each child. A small share of cases come from new gene changes in people with no family history. Some cases of type II and type IV are recessive, which means a child gets a changed gene from both parents, who usually have no signs.
How doctors diagnose it
Doctors look at your features, your medical history, and your family history. The main signs include wide-set inner eye corners, different eye colors, light hair, skin, or eyes, and deafness from birth. An eye exam with a slit-lamp, a microscope that lights up the eye, can check the inside of the eye and measure the distance between the eye corners. Genetic testing can confirm the diagnosis by finding the gene change. A rectal biopsy, a small tissue sample, can help confirm Hirschsprung disease.
Treatment
Treatment is aimed at each person's symptoms. A team of doctors may help, such as dermatologists, ophthalmologists, hearing specialists, gastroenterologists (digestive doctors), and speech-language pathologists. Options include:
- A cochlear implant, a device placed in the inner ear to send sound signals to the brain.
- Early help with communication, such as sign language, lip reading, and communication devices.
- Wearing clothing that protects the skin from the sun.
- Surgery for Hirschsprung disease or for bone and joint problems, if needed.
- Genetic counseling and special education or other support services.
Treating hearing loss early helps children with hearing loss from birth. It supports speech and language growth and social skills.
When to see a doctor
Have a child's hearing checked early if hearing loss is suspected. Catching hearing loss early helps children get timely support. Tell a doctor soon if a child with Waardenburg syndrome has a swollen belly, a poor appetite, or slow weight gain. These can be signs of Hirschsprung disease.
Call 911 or go to the emergency room if a child has severe belly pain, severe or ongoing vomiting, trouble breathing, or a big change in alertness.
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 help you find specialists, keep track of follow-up visits, and bring your test results together over the years.
Common questions
Does Waardenburg syndrome always cause hearing loss?
No, most people with Waardenburg syndrome have normal hearing. When hearing loss does happen, it is present from birth and can affect one or both ears. It happens more often in type II than in type I.
Can Waardenburg syndrome be passed to children?
Yes, it is usually passed down in families, and an affected parent has a 50% chance of passing it to each child. Some children are the first in their family to have it because of a new gene change.
What are the four types of Waardenburg syndrome?
The four types are numbered I to IV and differ by their features. Types I and II look much alike, but wide-set eyes almost always occur in type I. Type III also affects the arms and hands. Type IV also involves Hirschsprung disease.
Does Waardenburg syndrome shorten life?
No, people with Waardenburg syndrome have a normal life expectancy, although symptoms can affect daily life.
