Ectodermal dysplasia (ED) is a group of inherited conditions that affect body parts that grow from the ectoderm, which is the outer layer of the early embryo. In simple words, ED changes how your hair, teeth, nails, and sweat glands develop. It can also affect skin, eyelashes and eyebrows, oil glands, tear glands, salivary glands, and parts of the ears and nose. Because these structures grow differently, they may be missing, fewer than normal, shaped differently, thinner, weaker, dryer, or work less well.
Ectodermal dysplasia is a group of rare genetic conditions that affect body parts formed from the “outer” layer of the embryo (the ectoderm). These include the skin, hair, nails, teeth, and sweat glands. When these parts don’t form normally, people can have sparse hair, thin or brittle nails, missing or cone-shaped teeth, dry eyes and mouth, and trouble sweating (or no sweat at all). The most common subtype is hypohidrotic/anhidrotic ectodermal dysplasia (HED), where sweating is reduced or absent. Other subtypes (for example “hidrotic”) may have near-normal sweating but still affect hair and nails. Genes commonly involved include EDA, EDAR, EDARADD, WNT10A. MedlinePlus
ED is present from birth, even if some signs show later when teeth come in or when a child faces hot weather. ED is genetic, which means a change in one or more genes causes the condition. Different genes control different steps in the “blueprint” for hair, teeth, nails, and sweat glands. If one of these genes changes, that part may not form or function as it should. There are many types of ED. Some people have very mild signs; others have more obvious signs. Most people with ED have normal intelligence. Many live full lives with the right protection from heat, careful dental care, and simple daily routines for skin, hair, eyes, and mouth.
In early life, the embryo has three layers. The ectoderm is the top layer. It forms the skin surface and special “buds” that become hair follicles, teeth, nails, sweat glands, oil glands, and parts of the ears, eyes, and nose. Cells talk to each other using signals (like the EDA/EDAR/NF-κB pathway, the WNT pathway, and the TP63 network). These signals tell cells when to start, stop, shape, and place each structure. A gene change that weakens one of these signals can make the structure smaller, fewer, fragile, misshaped, or missing. That is why the key signs of ED are sparse hair, few or peg-shaped teeth, brittle nails, and reduced or absent sweating.
Types of ectodermal dysplasia
There are many named syndromes, but it is helpful to think about ED in a few simple ways.
A. Types based on sweating
Hypohidrotic / Anhidrotic ED (HED)
Sweat glands are few or missing. People overheat easily and have dry skin. This is the most common form. It often affects hair and teeth as well.Hidrotic ED (Clouston type)
Sweat glands are present, so heat problems are usually milder. The main signs are nail changes, hair changes, and thickened skin on hands and feet.
B. Types based on which parts are most affected
Hair-tooth-nail-sweat type: changes in all four.
Tooth-nail type: teeth and nails are more affected.
Hair-nail type: hair and nails are the main issues.
Tooth-dominant type: mainly missing or peg-shaped teeth.
C. Common named examples you may hear about
Hypohidrotic ED (often due to EDA, EDAR, or EDARADD gene changes).
Hidrotic ED (Clouston) (often due to GJB6 gene changes).
TP63-related ED syndromes (such as EEC or AEC syndromes) that can include cleft lip/palate or limb differences.
WNT10A-related ED (often strong tooth involvement and sometimes nail or sweat changes).
Tooth-nail syndromes (such as Witkop type), where teeth and nails are most affected.
Trichodento-osseous syndrome (teeth, hair, and bone features; linked to DLX3).
Remember: features overlap across types. The best way to name the exact type is by clinical exam plus genetic testing.
Causes
All true “causes” of ED are genetic. Below are 20 gene-level or pathway-level causes and mechanisms that doctors see in ED. You do not need all of these for diagnosis; usually one applies to a given person or family.
EDA gene changes
A change in the EDA gene weakens the main signal that starts sweat glands, hair, and teeth. This often causes hypohidrotic ED and may be X-linked (more often affects males).EDAR gene changes
A change in EDAR disrupts how the EDA signal is received, leading to fewer or misshaped teeth, hair, and sweat glands.EDARADD gene changes
A change in EDARADD affects the helper part of the same pathway, again reducing proper development of hair, teeth, and sweat glands.WNT10A gene changes
WNT10A helps form tooth buds and other ectodermal structures. Changes here often cause missing teeth and may also affect nails and skin.TP63 gene changes
TP63 guides early body patterning. Changes can cause ED with clefting of the lip or palate and sometimes hand/foot differences.GJB6 gene changes (Connexin-30)
GJB6 makes channels between cells. Changes cause Clouston (hidrotic) ED, with nail thickening, hair loss, and palm/sole skin thickening, usually with normal sweating.KRT14 gene changes (Keratin-14)
KRT14 supports skin and its appendages. Some changes cause ED spectrum disorders with skin pattern changes and nail/hair issues.KRT85 gene changes (Hair keratin)
This keratin supports hair shafts. Changes can lead to thin, fragile hair within an ED picture.DSG4 gene changes (Desmoglein-4)
DSG4 helps hair shaft anchoring. Changes can cause localized hypotrichosis with ED-like hair fragility.PAX9 gene changes
PAX9 is important for tooth development. Changes often cause missing molars and can sit within the ED–tooth agenesis spectrum.MSX1 gene changes
MSX1 also shapes tooth formation. Changes can lead to tooth agenesis and fit within ED-related tooth patterns.DLX3 gene changes
DLX3 affects hair, teeth, and bone. Changes can cause trichodento-osseous syndrome with ED-like tooth enamel and hair findings.NECTIN1 (PVRL1) gene changes
NECTIN1 helps cell-to-cell adhesion. Changes can cause cleft lip/palate–ectodermal dysplasia with tooth and hair issues.NECTIN4 gene changes
NECTIN4 changes can cause ED with syndactyly, mixing ED signs with webbed fingers or toes.LRP6 gene changes
LRP6 is a co-receptor in the WNT pathway. Changes can cause tooth agenesis and ED-spectrum features.KREMEN1 gene changes
KREMEN1 tunes WNT signals. Changes can reduce normal ectodermal development of hair/teeth/skin.Copy-number variants (CNVs) in ED genes
Sometimes a whole chunk of DNA near an ED gene is missing or duplicated, disturbing the gene’s level and causing ED features.De novo mutations
A new gene change occurs for the first time in the child (not present in either parent). The child shows ED even with no family history.Parental mosaicism
A parent has a gene change in some cells only, looks healthy, but can pass the change to a child who then has ED.Pathway-level dysfunction without a single named gene
In a minority of families, testing points to EDA/NF-κB, WNT, or TP63 pathway disruption even when one exact gene is not confirmed yet; the pathway problem still causes the ED pattern.
Key point: ED is not caused by pregnancy diet, vaccines, or infections. It is genetic, even when the exact gene has not yet been found.
Symptoms
Not everyone has all signs. The mix depends on the ED type and the gene involved.
Heat intolerance
Because sweat glands are few or missing, the body cannot cool well, so hot weather or exercise can cause overheating.Reduced or absent sweating (hypohidrosis/anhidrosis)
Skin may feel dry, and there may be no sweat even in heat.Dry skin (xerosis) and eczema-like rashes
Skin can be rough, itchy, and cracked, with flares after bathing, in winter, or with fragranced products.Sparse scalp hair (hypotrichosis)
Hair may be thin, slow-growing, fragile, or patchy; eyebrows and eyelashes may be sparse.Brittle or thickened nails
Nails may be thin, ridged, break easily, or in some types thicken and lift.Missing teeth (hypodontia/oligodontia)
Baby and adult teeth may be fewer than normal.Peg-shaped or small teeth
The teeth that do form may be cone-shaped, small, or have thin enamel.Dry mouth (reduced saliva)
Saliva helps swallow, speak, and protect teeth. Dryness can cause cavities, bad breath, and sore mouth.Dry eyes (reduced tears)
Eyes may feel gritty or burning, with light sensitivity and frequent blinking.Dry nose with crusting and nosebleeds
The inside of the nose can crust, leading to bleeds and stuffy feeling.Dry airway and recurrent colds/bronchitis
Sticky, dry mucus can make coughs and infections happen more often.Facial features linked to ED
Some people have frontal bossing (prominent forehead), a saddle nose, thin lips, and periorbital dark rings, especially in hypohidrotic ED.Slow weight gain in hot weather
Poor heat control can lower appetite or activity, especially in infants during summer.Thick palms/soles or palm lines (in some types)
Skin can become thick, cracked, and tender, often in hidrotic forms.Psychosocial impact
Visible changes in hair, teeth, and nails can affect self-confidence and social comfort, even when health is otherwise good.
Diagnostic tests
Below are 20 tests doctors use to confirm ED, map its features, guide care, and identify the gene. Your clinician chooses the right set based on age, symptoms, and family history.
A) Physical-exam–based assessments (bedside observations)
Full skin, hair, nail, and gland exam
The doctor looks for sparse hair, dry skin, nail changes, reduced sweating, and thick palms/soles, and checks eyebrows, eyelashes, and body hair.Tooth count and shape charting
The dentist or doctor counts baby and adult teeth, notes peg-shaped or small teeth, and looks for thin enamel.Heat stress history and observation
Clinician reviews overheating episodes, checks sweat during mild warm conditions, and assesses tolerance to everyday heat.Facial feature assessment
The clinician notes features often seen in ED—forehead shape, nasal bridge, lip fullness, and eye area—to support the pattern.
B) “Manual” office tests (simple tools or quick procedures)
Schirmer tear test
A small paper strip under the eyelid measures tear production over a few minutes to confirm dry eyes.Hair pull/tug and trichoscopy
Gentle tug checks hair fragility; handheld scope (trichoscopy) shows hair shaft patterns, miniaturization, and broken hairs.Starch–iodine or indicator powder sweat test
A powder changes color with sweat. Under warmth, areas that do not change color suggest reduced sweating.Saliva flow (sialometry)
You spit into a tube over a set time to measure saliva volume, confirming dry mouth.
C) Laboratory and pathological tests
Genetic testing—targeted ED gene panel
A blood or saliva sample looks at many ED-related genes at once (for example, EDA, EDAR, EDARADD, WNT10A, TP63, GJB6, and others). This is now the core test to confirm the exact subtype.Whole-exome or whole-genome sequencing
If the panel is negative or the case is complex, broader testing can find rare or new gene changes and copy-number variants.Copy-number analysis (CNV by microarray or NGS)
Checks for deletions/duplications around ED genes when single-letter testing is normal but suspicion stays high.Skin biopsy with histology
A tiny skin sample under the microscope can show reduced or absent sweat glands, abnormal hair follicles, or gland changes supporting ED.Tooth enamel and dentin assessment (micro-analysis when needed)
Dental specialists may analyze enamel thickness, mineralization, and tooth structure to plan crowns, implants, or dentures.Basic labs to exclude look-alikes
Occasionally doctors run thyroid, iron, zinc, or autoimmune screens to rule out other causes of hair, nail, or skin changes that can mimic ED.
D) Electrodiagnostic and physiologic sweat/skin tests
QSART (Quantitative Sudomotor Axon Reflex Test)
Uses a tiny electrical stimulus with a sweat-inducing drug on the skin to measure sweat volume at different sites; helps prove reduced sweat function.Electrochemical Skin Conductance (ESC) testing
Measures how well the skin conducts a mild current related to sweat gland function; lower values suggest hypohidrosis.Sympathetic Skin Response (SSR)
Records skin’s electrical changes to a stimulus; blunted responses can support reduced sweat activity in ED.
E) Imaging and specialized visualization
Panoramic dental X-ray (OPG)
Shows all teeth (present and missing), tooth buds, roots, and jaw bone, which helps plan dental treatment.Cone-beam CT (CBCT) for dental planning
A 3-D scan helps plan implants, bridges, or dentures by showing bone volume and exact tooth positions.Craniofacial imaging or ENT assessment (as indicated)
CT/MRI or endoscopic views may be used if there are clefting, sinus, ear, or salivary gland concerns to map anatomy for surgery or therapy.

Frequently Asked Questions (FAQ)
1) Is there a cure for ED?
Not yet for most types. Care focuses on symptoms (cooling, skin, eyes, mouth, dental reconstruction). A prenatal protein therapy for XLHED (Fc-EDA/ER-004) is in clinical trials and has restored sweating in treated children, but it is not yet approved as standard care. New England Journal of MedicineClinicalTrials.govPubMed
2) Why is overheating such a big concern?
Many people with HED do not sweat. Sweating is the body’s main cooling system. Without it, overheating can become dangerous fast—especially in babies and in hot weather. Planning, AC, and cooling gear are essential. Ectodermal Dysplasias Foundation
3) Can children with ED play sports?
Yes—with a heat plan: cooling breaks, shade, cold fluids, and careful monitoring. Choose cooler parts of the day and talk to coaches. Ectodermal Dysplasias Foundation
4) When are dental implants possible?
Usually after most facial growth is complete (late teens), often after orthodontic preparation; some specialized pediatric strategies exist but are individualized. Ectodermal Dysplasias Foundation+1
5) Do dentures in young kids really help?
Yes. Early dentures can improve chewing, speech, social confidence, and support facial growth—then get remade as the child grows. Ectodermal Dysplasias Foundation
6) What can we do about dry eyes?
Start with preservative-free tears and bedtime ointment. If that’s not enough, punctal plugs conserve tears; severe cases may benefit from PROSE scleral lenses. AAOPMC
7) Is there a medicine to make more saliva?
Yes—pilocarpine or cevimeline can stimulate saliva in appropriate adults. They have side effects (often sweating), so your clinician will decide if they are right for you. Drugs.comFDA Access Data
8) Why do some people with ED also have immune problems?
A separate condition, EDA-ID (often due to IKBKG/NEMO variants), combines ED features with primary immunodeficiency. These patients may need immunology care, IVIG/SCIG, tailored vaccines, and in severe cases, HSCT. JAMA NetworkPMC
9) Are there special eye surgeries for ED?
Severe tear-drain problems may need permanent punctal occlusion or lacrimal surgeries; most people do well with drops, ointments, and reversible plugs. Ectodermal Dysplasias Foundation
10) Do topical steroids thin the skin?
They can if overused. Use the lowest effective potency for short courses, then switch to moisturizers and (when appropriate) steroid-sparing creams like tacrolimus/pimecrolimus. Ectodermal Dysplasias Foundation
11) What toothpaste and mouth rinse are best?
Use fluoridated toothpaste twice daily and ask about professional fluoride varnish. For dry mouth, saliva-friendly rinses (alcohol-free) are best. AAPD
12) Is prenatal testing or early diagnosis possible?
Yes. Families with known mutations can consider carrier testing and prenatal imaging such as tooth-germ sonography in mid-gestation, guided by genetics teams. Ektodermale Dysplasie
13) Can ED affect school and work?
Yes—especially in heat. Letters supporting AC, water access, and cooling breaks help students and workers participate safely. Ectodermal Dysplasias Foundation
14) Are wigs or hairpieces common?
Many people choose them for appearance and comfort. Gentle scalp care and sun protection are important regardless. PubMed
15) What is the long-term outlook?
With good heat management, dental reconstruction, eye/skin care, and (when needed) immunology support, most people live full, active lives. Advances—particularly prenatal therapy for XLHED—are promising but still under study. New England Journal of MedicineClinicalTrials.gov
