EEC Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats EEC Syndrome?
A medical geneticist, a doctor who diagnoses inherited conditions, often helps lead care for EEC syndrome. Because the syndrome can affect many body parts, the care team may also include plastic surgeons, dentists, eye doctors, and speech therapists. 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 EEC syndrome?
EEC syndrome is a rare genetic disorder. The name stands for ectrodactyly, ectodermal dysplasia, and cleft lip or palate. It is also called ectrodactyly-ectodermal dysplasia-clefting syndrome.
Ectrodactyly means part or all of the central fingers or toes are missing. Ectodermal dysplasia means problems with the hair, teeth, nails, skin, and sweat glands. A cleft lip or cleft palate is a gap in the upper lip or in the roof of the mouth. Symptoms can vary greatly from one person to another.
Symptoms
Symptoms are highly variable, even among members of the same family. They can include:
- Hands and feet: missing or malformed fingers or toes, often the middle ones, and sometimes webbing or fusion of fingers or toes.
- Mouth and face: cleft lip with or without cleft palate, an undeveloped upper jaw, and a broad nasal tip.
- Skin, hair, and nails: dry skin, sparse and slow-growing scalp hair, sparse eyelashes or eyebrows, and thin, malformed nails.
- Teeth: missing, malformed, or underdeveloped teeth. Tooth decay is common and often severe.
- Sweating and mouth: a reduced ability to sweat. This can cause heat intolerance and fever. Dry mouth is also possible.
- Eyes: blocked tear ducts that cause frequent tearing, eye infections, and sensitivity to light.
- Other: some people have kidney or urinary tract problems, hearing loss, or small, malformed ears.
Intelligence is usually unaffected. Language development may be delayed. A cleft lip or palate or hearing loss can be the reason.
Causes and who gets it
Most cases are caused by changes (mutations) in the TP63 gene. This gene makes a protein called p63. The p63 protein plays a critical role in early development. It is especially important for the skin, hair, teeth, and nails. A small percentage of cases with features like EEC syndrome are caused by chromosome changes instead.
EEC syndrome is inherited as an autosomal dominant trait. Dominant means only one copy of the changed gene is needed for the disorder to appear. The risk of passing the changed gene from an affected parent to a child is 50% for each pregnancy. Some cases occur with no family history, because of a new gene change.
EEC syndrome affects males and females in equal numbers.
How doctors diagnose it
Diagnosis is based on the typical symptoms, patient history, a thorough exam, and special tests. These may include:
- X-rays to look at the limbs and face.
- A complete eye exam to look for problems such as blocked tear ducts.
- A kidney ultrasound.
- A skin biopsy, which studies a small sample of skin.
- Genetic testing, which can confirm the diagnosis. Testing the TP63 gene is the first test.
A routine ultrasound during pregnancy can sometimes show these signs.
Treatment
Treatment is aimed at the symptoms each person has. It may take a team of specialists. The team can include pediatricians, plastic surgeons, bone surgeons, dentists, speech therapists, eye doctors, hearing specialists, and skin doctors.
- Reconstructive surgery may help with defects that limit function, such as ectrodactyly, webbed fingers, and cleft lip or palate.
- Dental surgery and corrective devices can treat misshapen teeth. Dentures may be needed if teeth are missing.
- Artificial tears may help blocked tear ducts, and surgery may be needed for them.
- Emollients, which soften the skin, may be used for dry skin.
- Hearing aids may help if hearing is impaired.
- Genetic counseling may help affected people and their families.
When to see a doctor
Families should talk with their doctor and medical team about their own case, the symptoms, and the overall outlook.
Some problems need prompt attention. Reduced sweating can cause heat intolerance and fever, so children need close watching for overheating during long activity and in summer. Eye problems such as frequent tearing and infection need an eye doctor. Long-lasting inflammation can harm vision. Surgery may be needed for a urinary tract problem when pain or infection is present.
Call 911 or go to the emergency room if you have fainting, confusion or trouble waking, or trouble breathing.
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 with checkups and keep track of care from many specialists. They can also refer you to a geneticist and support families who want genetic counseling.
Common questions
Is EEC syndrome inherited?
Yes, it can be passed down in families, but some cases happen with no family history. EEC syndrome is inherited as an autosomal dominant trait, which means one changed copy of the gene is enough. Other cases come from a new gene change.
Does EEC syndrome affect intelligence?
Usually not. Intelligence is usually unaffected in children with EEC syndrome. Language development may be delayed because of a cleft lip or palate or hearing loss.
How is EEC syndrome treated?
Treatment is aimed at the specific symptoms each person has. It can include reconstructive surgery, dental care, artificial tears for blocked tear ducts, hearing aids, and genetic counseling. A team of specialists often works together.
Does EEC syndrome affect males and females equally?
Yes. EEC syndrome affects males and females in equal numbers.
