Trüeb–Burg–Bottani Syndrome

Trüeb–Burg–Bottani syndrome refers to a genetic disorder affecting body parts that come from the outer embryonic layer (the ectoderm)—especially hair, teeth, nails, skin, sweat glands—and sometimes fingers/toes (syndactyly). The most striking hair sign is corkscrew-shaped hair (a form of pili torti). People can also have nail changes, tooth defects (missing or small teeth), thick skin on palms/soles, and sometimes webbed or fused digits. The original families looked autosomal dominant, but later reports described autosomal recessive families with a very similar “corkscrew hair” ectodermal dysplasia picture. Today, many clinicians would consider this presentation within the broad family of ectodermal dysplasias, and—when features fit—especially the WNT10A-related spectrum that includes OODD and the closely related Schöpf–Schulz–Passarge syndrome. MDPI+3PubMed+3PubMed+3

Trüb-Burg-Bottani syndrome is an extremely rare inherited condition that affects structures that come from the body’s ectoderm—mainly hair, teeth, nails, and skin—and is often accompanied by syndactyly (joined fingers or toes). It was described in the medical literature as “ectodermal dysplasia with corkscrew hairs” and also appears in rare-disease catalogs as autosomal-dominant tricho-odonto-onychodysplasia with syndactyly (TODS). In practical terms, people can have sparse or twisted hair, abnormal or missing teeth, nail changes, and webbing or fusion between digits. Wellness Advocate+2PubMed+2

Orphanet explicitly lists “Trüeb–Burg–Bottani syndrome” as an obsolete entity, pointing users to the underlying ectodermal-dysplasia diagnoses (the first description remains the 1994 Trüeb et al. paper). Practically, this means you are most likely to see “ectodermal dysplasia with corkscrew hairs,” “tricho-odonto-onychodysplasia with syndactyly,” or OODD (WNT10A-related) on modern reports. Orpha+1

Other names

You may find one or more of the following labels used for the same or very similar clinical pictures in the literature:

• Ectodermal dysplasia with corkscrew hairs (EDCH) — the descriptive name used in the 1994 report. PubMed

• Tricho-odonto-onychodysplasia with syndactyly — emphasizes hair, tooth, nail changes and fused digits; the 1994 family looked autosomal dominant. PubMed

• Autosomal dominant trichoodontoonychodysplasia-syndactyly — as cataloged by disease databases that cross-index the 1994 paper. MalaCards

• Odonto-onycho-dermal dysplasia (OODD) — an autosomal recessive, WNT10A-related diagnosis that overlaps strongly with hair–tooth–nail-skin findings. Not all “Trüeb–Burg–Bottani” cases are OODD, but clinicians often consider OODD in similar presentations. Cell+1

---

Types

Because the eponym is now obsolete, clinicians sort people by inheritance pattern and gene rather than by the old label:

1. Autosomal-dominant corkscrew-hair ectodermal dysplasia (Trüeb–Burg–Bottani original families). The index report described a dominant pedigree with corkscrew hairs, tooth and nail changes, and syndactyly. The causal gene was not identified at the time. PubMed

2. Autosomal-recessive “corkscrew-hair” ectodermal dysplasia. A later family had a similar picture (corkscrew hairs, dental anomalies, syndactyly) but segregating recessively. Again, gene-level proof was not provided in that older report. PubMed

3. WNT10A-related ectodermal dysplasia (OODD and close neighbors). Bi-allelic WNT10A variants cause OODD, a highly overlapping syndrome with severe tooth agenesis, nail dysplasia, palmoplantar keratoderma, variable sweating problems, and hypotrichosis; WNT10A can also present as hypohidrotic ED or Schöpf–Schulz–Passarge. Cell+2OUP Academic+2

4. Other ectodermal-dysplasia genes with overlapping features. Variants in EDA/EDAR/EDARADD (ectodysplasin–NF-κB pathway) and TP63 can produce combinations of hair, tooth, nail, sweating, and limb differences (including syndactyly), sometimes mimicking the historic “Trüeb–Burg–Bottani” picture. MedlinePlus+2MDPI+2

Causes

Because “Trüeb–Burg–Bottani syndrome” is an umbrella, obsolete label, the underlying cause depends on the precise modern diagnosis. Below are causes and mechanisms reported in the overlapping ectodermal-dysplasia conditions that present like the original 1994 families. Each item explains the idea in simple language.

1. Unknown gene in the original dominant families. The first report documented clear autosomal-dominant inheritance but did not identify a gene—so an undiscovered or unsolved gene remains a plausible cause for that pedigree. PubMed

2. Autosomal-recessive, gene-unsolved variant of the same phenotype. A later “corkscrew hair” family segregated recessively, again without a gene identified at the time. PubMed

3. WNT10A bi-allelic pathogenic variants (OODD). These disrupt Wnt signaling, a pathway crucial for tooth, hair, nail, and skin development. Cell+1

4. EDA gene variants (X-linked hypohidrotic ED). Disrupted ectodysplasin A signaling impairs sweat glands, teeth, hair, and nails; female carriers may show patchy sweat patterns. MedlinePlus+1

5. EDAR variants (autosomal hypohidrotic ED). Altered EDAR receptor signaling similarly affects ectodermal appendages. MedlinePlus

6. EDARADD variants (autosomal hypohidrotic ED). Disruption of the EDAR adaptor protein leads to a similar cascade of ectodermal abnormalities. MedlinePlus

7. TP63 variants (TP63-related disorders). TP63 regulates limb and ectodermal development; syndactyly plus hair/teeth/nail changes point clinicians to this pathway in some look-alike cases. NCBI

8. Keratins of hair/nail matrix (e.g., KRT85/KRTHB5). Some ectodermal-dysplasia subtypes result from hair/nail keratin defects, producing brittle hair and nail dysplasia. GeneSkin

9. Broader WNT-pathway disruption. WNT10A is the best-known, but Wnt signaling broadly orchestrates ectodermal organ patterning and tooth morphogenesis. ScienceDirect+1

10. Ectodysplasin–NF-κB pathway disruption. EDA/EDAR/EDARADD variants block a key skin-appendage signaling axis, giving hair/teeth/sweat anomalies. MDPI

11. Modifier genes and variable expressivity. Even within the same gene (e.g., WNT10A), the severity can vary widely inside families, implying modifier effects. Peking University

12. De novo (new) variants. Some dominant ectodermal dysplasias arise anew in a child, so family history can be absent. (General ED genetics.) Actas Dermo-Sifiliográficas

13. Mosaicism in a parent. A parent with mosaic disease/variant can have mild signs but transmit a pathogenic variant. (General ED genetics.) Actas Dermo-Sifiliográficas

14. Developmental hair-shaft malformation (pili torti). The hallmark corkscrew hair shape reflects abnormal hair-shaft architecture from faulty follicle development. Wikipedia

15. Abnormal tooth bud development (hypodontia/oligodontia). Faulty signaling during odontogenesis leads to few or small teeth. Nature

16. Nail-matrix dysgenesis (onychodysplasia). Disrupted keratinization in nail units produces thin, ridged, or malformed nails. GeneSkin

17. Eccrine gland maldevelopment (hypo/anhidrosis) or dysregulation (hyperhidrosis). Sweat gland number/function is altered in many EDs. MedlinePlus+1

18. Palmoplantar keratinization changes. Signaling defects shift skin toward thickened, hyperkeratotic palms/soles. Cell

19. Ocular surface vascular changes (rare). Conjunctival neovascularization has been noted in the “corkscrew hair” ectodermal dysplasia literature. Wikipedia

20. Contiguous-gene mechanisms (rare theoretical). Classical genetics recognizes that adjacent gene losses can create blended phenotypes; such mechanisms are occasionally considered in complex ED pictures. Karger Publishers

Symptoms and signs

1. Corkscrew / twisted hairs. The hair shaft twists along its length (a kind of pili torti), making hair look wiry, fragile, or “spiraled.” PubMed+1

2. Scalp bumps or keloid-like scars. Some people develop thickened raised areas on the scalp. Wikipedia

3. Follicular plugging / keratosis pilaris. Small rough bumps appear where hair exits the skin. Wikipedia

4. Dry skin and eczema-like patches. Skin may be dry or eczematous; moisturizers are commonly needed. Wikipedia

5. Palmoplantar keratoderma. Skin of palms/soles becomes thick and rough. Wikipedia

6. Nail dysplasia. Nails can be thin, ridged, split, or oddly shaped. Wikipedia

7. Tooth anomalies (hypodontia/oligodontia). Missing, small, or peg-shaped teeth; late eruption is common in related EDs. OUP Academic

8. Smooth tongue with reduced papillae (sometimes). A smooth-looking tongue surface may be noticed in OODD. Cell

9. Sweating problems — either reduced sweating and heat-intolerance or, in some, excess sweating of palms/soles. MedlinePlus+1

10. Syndactyly. Fingers or toes may be webbed or fused in part. PubMed

11. Conjunctival neovascularization (rare). New small blood vessels can grow on the eye’s surface in some reported cases. Wikipedia

12. Characteristic facial look (variable). Some EDs share periorbital folds, saddle nose, and small jaw; not all individuals show this. NFED

13. Itchy, rough scalp dermatitis. Inflammation of the scalp has been noted in series of patients with the corkscrew-hair phenotype. Wiley Online Library

14. Dermatoglyphic hypoplasia (subtle). Fine skin ridge patterns (fingerprints) may be under-developed in some reports. PubMed

15. Learning difficulties in a few historical cases. One recessive case described developmental delay; this is not universal and depends on the underlying syndrome. PubMed

Diagnostic tests

A) Physical examination

1. Full skin and hair exam. A dermatologist inspects the scalp hair for spiral/twisted shafts and looks for keloid-like thickening and follicular bumps. This bedside exam anchors the diagnosis. PubMed+1

2. Nail inspection. Nails are checked for thickness, ridging, splitting, or abnormal shape—typical signs in ectodermal dysplasia. Wikipedia

3. Oral/dental exam. Counting teeth, noting peg-shaped or missing teeth, and looking for delayed eruption points the team toward an ED pattern. OUP Academic

4. Hands/feet exam for syndactyly. Webbing or fusion of digits is documented and photographed for surgical planning if needed. PubMed

5. Sweating assessment and heat-intolerance history. Simple questions plus exam (dryness vs clamminess) can suggest hypo- or hyperhidrosis. MedlinePlus

B) “Manual” office tests

6. Minor’s starch–iodine test (sweat mapping). Iodine is painted on skin, then starch is dusted; sweating turns it dark, mapping areas of sweat loss or excess—useful in EDs and hyperhidrosis. Shanghai Chest+1

7. Dermoscopy after starch–iodine. A handheld scope can show blue-violet dots of active sweat-duct openings after the test. JAAD

8. Hair-pull and trichoscopy. Collecting hairs and inspecting them (or using in-office trichoscopy) shows the twisted/corkscrew shafts. Wikipedia

9. Dental charting and panoramic screening referral. Chairside charting guides x-ray choices and genetic testing. OUP Academic

10. Photographic documentation (skin, nails, digits). Serial standardized photos help track changes and plan care. (Standard ED practice.) Medscape

C) Laboratory & pathology / genetics

11. Targeted ED gene panel (WNT10A, EDA, EDAR, EDARADD, ±TP63, selected keratins). Modern panels confirm many look-alike cases and clarify inheritance. MDPI+1

12. Single-gene testing for WNT10A when OODD suspected. Bi-allelic WNT10A variants clinch OODD and related phenotypes. Cell

13. Skin biopsy (selected cases). If diagnosis is unclear, histology may rule out other disorders; most EDs are genetic diagnoses, so biopsy is not always required. (General ED workup.) Medscape

14. Hair-shaft light or electron microscopy. Microscopy depicts grooves, twists, and fractures expected in pili torti-like hair. Studies in genetically defined EDs show these structural changes. BioMed Central

15. Sweat-pore counts / carrier testing in ED families. Starch–iodine or pore counts can reveal mosaic or reduced sweating patterns in ED families. PubMed+1

D) Electrodiagnostic / physiologic sudomotor tests

16. QSART (Quantitative Sudomotor Axon Reflex Test). Measures nerve-evoked sweating at the skin—useful if sweat function is uncertain. PMC+1

17. Thermoregulatory Sweat Test (TST). Whole-body sweat response to heat is visualized to quantify heat-intolerance risk. PMC+1

18. Gravimetric sweat measurement (for hyperhidrosis). Weighing filter paper before/after collection estimates sweat rate; sometimes used in management. PMC

E) Imaging and specialized examinations

19. Dental panoramic radiograph (OPG) ± dental CT. Shows missing tooth buds, root/crown development, and helps plan dental rehabilitation. (OODD/WNT10A literature.) Nature

20. Hand/foot x-rays and ophthalmic exam. X-rays define the extent of syndactyly for surgery; an eye exam checks rare conjunctival changes. PubMed+1

Non-pharmacological treatments (therapies & other supports)

Each item includes what it is, why it’s done (purpose), and how it helps (mechanism).

Important regulatory reality about medicines

There are no FDA-approved drugs specifically for Trüb-Burg-Bottani syndrome. When medicines are used, they treat symptoms or associated conditions (e.g., skin inflammation, dry eye, infections). Below I list 20 commonly used, FDA-labeled products with their drug class, typical labeled dosing/time, purpose, mechanism, and notable side effects—but for their approved indications, not for TBBS specifically. Any off-label use must be directed by your clinician. Science.gov

Additionally, there are no FDA-approved stem-cell or “regenerative” drugs for ectodermal dysplasias or TBBS; the FDA warns consumers about unapproved stem-cell products. NCBI

Dietary molecular supplements

There is no supplement proven to “treat” TBBS. Some nutrients support skin, nail, hair, bone, and enamel biology in general. Evidence is mixed; high doses can cause harm. Always confirm need, dose, and interactions with your clinician.

1. Biotin—May help brittle nails in deficiency; routine mega-dosing isn’t supported; also interferes with lab tests at high doses. Typical OTC 30–100 mcg/day if dietary intake is low. Mechanism: cofactor in keratin infrastructure. FDA Access Data

2. Vitamin D—Supports bone/tooth mineralization; correct deficiency per blood levels (often 800–2000 IU/day maintenance, individualized). Mechanism: calcium/phosphate regulation. FDA Access Data

3. Calcium—Meets daily needs when diet is low (total intake target typically 1000–1200 mg/day from diet + supplements). Mechanism: hydroxyapatite formation in bone/teeth. FDA Access Data

4. Zinc—Deficiency impairs wound healing and can cause nail/hair changes; supplement only if low (commonly 8–11 mg/day intake targets). Mechanism: enzyme cofactor for epithelial repair. FDA Access Data

5. Omega-3 fatty acids (EPA/DHA)—Anti-inflammatory effects may help general skin comfort; dose ranges vary (commonly 1 g/day combined EPA/DHA). Mechanism: lipid mediators that temper inflammatory pathways. FDA Access Data

6. Vitamin A (retinoids)—Essential for epithelial differentiation; excess is toxic. Use only if deficient and under supervision (RDA level intake, avoid high-dose). Mechanism: retinoid receptor signaling for keratinization. FDA Access Data

7. Iron—Treat only documented deficiency (common adult dose 18–65 mg elemental iron/day until replete). Mechanism: supports hair follicle cycling and oxygen delivery. FDA Access Data

8. Protein sufficiency—Ensure adequate daily protein (roughly 0.8–1.0 g/kg/day, individualized) to support tissue repair and dental work recovery. Mechanism: provides amino acids for keratin/collagen. Science.gov

9. Folate/B12—Correct deficiency that can worsen mucosal health; dose per lab results (e.g., folic acid 400 mcg/day; B12 1,000 mcg in deficiency under care). Mechanism: DNA synthesis for rapidly dividing epithelial cells. FDA Access Data

10. Magnesium—Adequate intake supports mineral metabolism (310–420 mg/day from food + supplements if needed). Mechanism: cofactor in hundreds of enzymatic reactions including bone. FDA Access Data

Immunity booster / regenerative / stem-cell drugs

There are no FDA-approved “immunity booster,” regenerative, or stem-cell drugs for TBBS or ectodermal dysplasias. Unapproved stem-cell products marketed for “skin/hair regeneration” are specifically flagged by FDA as potentially unsafe. Appropriate care is supportive; clinical trials (if available) are the ethical route for novel therapies. NCBI

Surgeries and procedures

1. Syndactyly release—Separates digits using flaps/skin grafts to improve grasp, pinch, and footwear comfort; timing and technique vary by web space and involvement. BioRxiv

2. Secondary web-space revisions—Scar contracture or growth can require touch-up procedures to maintain function and prevent tethering. BioRxiv

3. Dental implants (when jaw growth allows)—Replaces missing teeth to restore chewing, speech, and aesthetics; often staged after orthodontic preparation. Science.gov

4. Bone grafting for implant sites—Augments thin alveolar bone to support implants or prostheses for durable dental rehabilitation. Science.gov

5. Nail procedures (e.g., partial matricectomy)—Selected for painful, chronically dystrophic nails or recurrent infections to relieve symptoms. CheckOrphan

When to see a doctor urgently vs. routinely

Urgent: rapidly worsening hand pain/swelling after digit surgery, deep skin fissures with spreading redness/fever, eye pain/vision change, uncontrolled bleeding, new medication reactions (hives, wheeze, facial swelling). These can indicate infection or serious adverse drug effects. BioRxiv

Routine (soon): painful or loosening dental work, recurrent mouth sores, chronic skin cracking, nail infections, worsening dryness despite care, or functional limits from syndactyly. Early review prevents escalation and protects long-term function. Science.gov

---

Diet: simple eat / avoid tips

Eat more: (1) soft, protein-rich foods (eggs, yogurt, lentils) for tissue repair; (2) calcium- and vitamin D-rich foods (dairy, fortified foods, small fish with bones); (3) high-fiber fruits/vegetables for overall health; (4) healthy fats with omega-3s (fish, walnuts); (5) plenty of water for skin/eye/mouth comfort. Avoid or limit: (6) sticky/chewy sweets that cling to enamel; (7) frequent sugary sips between meals; (8) very hard foods that chip restorations; (9) alcohol/tobacco (healing, dryness); (10) unnecessary high-dose supplements without labs.

FAQs

1) Is TBBS the same as ectodermal dysplasia?
TBBS fits within the ectodermal dysplasia spectrum that affects hair, teeth, nails, and skin; it has been described under several names and is now often handled as a subtype within that group. Orpha+1

2) Is there a gene test?
Panels for ectodermal dysplasia genes exist. A specific “TBBS gene” hasn’t been firmly established in the literature; testing looks for known ED genes with overlapping features. PubMed

3) Is there a cure?
No cure. Care is feature-directed, and outcomes improve with early, coordinated dental, dermatologic, and surgical support. Science.gov

4) Are there approved drugs for TBBS?
No. Medicines treat symptoms/complications (e.g., dermatitis, infections, dry eye), not the underlying syndrome. Science.gov

5) Are stem-cell therapies available?
No approved stem-cell therapies for this condition; FDA warns about unapproved products. NCBI

6) Will dental implants work?
With planning, implants can restore function and appearance once jaw growth and bone support are suitable. Science.gov

7) When should syndactyly be separated?
Timing is individualized based on which webs are fused and child growth; hand-surgery teams plan the safest window. BioRxiv

8) Can hair grow normally with treatment?
Topical minoxidil may cosmetically thicken scalp hair for some, but benefits last only with continuous use and are not disease-specific. FDA Access Data

9) Is skin care lifelong?
Yes—daily emollients and gentle routines lower cracking/infection risk across life. Science.gov

10) Are eyes at risk?
Dry-eye symptoms can occur in ectodermal dysplasias; ophthalmology-directed care reduces surface injury. Science.gov

11) Can children participate in sports?
Usually yes, with footwear, hand protection, and hydration strategies tailored to the child. BioRxiv

12) Will my child need many surgeries?
Many need one or more hand procedures and staged dental work; other surgeries are case-by-case. BioRxiv+1

13) How often are dental visits?
Typically every 3–6 months in childhood and during active reconstruction. Science.gov

14) What about school?
Most students do well with reasonable accommodations (hydration, temperature control, appointment flexibility). Science.gov

15) Where can families learn more?
Patient-centric resources on ectodermal dysplasias and coordinated dental care offer practical guidance. Science.gov
