Brachyolmia-Amelogenesis Imperfecta Syndrome

Brachyolmia-amelogenesis imperfecta syndrome is a very rare, inherited condition that affects the spine, body height, hips, and teeth. Children grow with a short trunk and often mild short stature. X-rays show flattened vertebral bodies (called platyspondyly) and the pelvis may look broad; the femoral necks can be long with coxa valga (the thighbone angling outward). The spine can curve (scoliosis). Teeth are affected from baby teeth to adult teeth because the enamel (the hard, outer layer) is thin or almost absent, which is called amelogenesis imperfecta. The condition is usually autosomal recessive, meaning a child inherits two non-working copies of a gene—one from each parent. The main known gene is LTBP3, which helps control TGF-β signaling, a pathway important for bone, cartilage, and enamel formation. In a few families, doctors have also noticed heart valve problems or enlarged aortic root/aneurysms, so some heart checks are recommended. ncbi.nlm.nih.gov+3rarediseases.info.nih.gov+3orpha.net+3

Brachyolmia–amelogenesis imperfecta (AI) syndrome. This ultra-rare genetic condition combines a short-trunk skeletal dysplasia (brachyolmia) with severe enamel defects (AI), most often linked to bi-allelic variants in LTBP3 that impair TGF-β signaling in bone and tooth development. Brachyolmia–AI syndrome means a person is born with a short trunk, flattened spinal bones, and sometimes curved spine (scoliosis), plus very thin or almost absent enamel that chips easily and causes tooth sensitivity, cavities, and early tooth wear. The bone findings can include mild vertebral flattening, broad pelvis, elongated femoral necks (coxa valga), and short stature. Some families also report heart valve or aortic root issues, so screening may be advised. The enamel problem is syndromic AI: enamel is poorly formed, so teeth need early, gentle, protective dental care. Because it is genetic, management focuses on lifelong prevention, protection, pain control, physical therapy, and selected procedures when needed. orpha.net+1

Other names

This syndrome has been described in the literature using several names. They point to the same or closely overlapping clinical picture:

• Dental anomalies and short stature (DASS). This title highlights short stature with brachyolmia and severe enamel defects. ncbi.nlm.nih.gov+1

• Brachyolmia with amelogenesis imperfecta. The descriptive label often used in genetics papers and case reports. academic.oup.com+1

• Platyspondyly with amelogenesis imperfecta. Emphasizes the flattened vertebral bodies. disease-ontology.org

• Selective tooth agenesis 5 / STHAG6 (contextual synonym lists). Reported in ontology resources connected with LTBP3-related dental phenotypes. zfin.org

Types

There is one core genetic entity here—LTBP3-related brachyolmia with enamel defects—so “types” are best thought of as clinical subpatterns within the same disorder:

1. Classic skeletal-dental form. Short trunk, platyspondyly, coxa valga, scoliosis plus severe enamel hypoplasia/hypomineralization. rarediseases.info.nih.gov

2. Cardiovascular-involved form (subset). Some families show valve prolapse or aortic root dilation/aneurysms; this requires heart surveillance though it is not universal. ncbi.nlm.nih.gov

3. Severity spectrum. Even inside one family, spine changes, height, and enamel loss can vary (inter- and intra-familial variability). ncbi.nlm.nih.gov

Takeaway: it is one disease with a spectrum of bone, tooth, and occasionally heart findings, all rooted in LTBP3 biology. academic.oup.com

Causes

The true root cause is pathogenic variants in LTBP3. Below are 20 clear factors that either cause the syndrome (genetic) or explain how it produces the signs (mechanistic contributors). I state them simply, but all flow from LTBP3/TGF-β biology.

1. Biallelic LTBP3 mutations. Two damaging variants (autosomal recessive) cause the disorder. academic.oup.com

2. Loss of latent TGF-β binding/trafficking. LTBP3 helps store and deliver TGF-β in the extracellular matrix; loss disrupts signaling. academic.oup.com

3. Enamel matrix formation failure. TGF-β dysregulation disturbs ameloblast function → thin or absent enamel (AI). MDPI

4. Disordered vertebral growth plate signaling. TGF-β is vital for cartilage/bone growth; imbalance leads to platyspondyly. academic.oup.com

5. Altered collagen/elastin microenvironment. Matrix defects change bone and tooth biomechanics. academic.oup.com

6. Frameshift/nonsense variants. Truncating changes can abolish protein function. MDPI

7. Splice variants. Abnormal splicing can remove crucial domains (shown in case studies). MDPI

8. Missense variants in functional domains. Single amino-acid changes can destabilize LTBP3 or its binding. academic.oup.com

9. Founder variants in specific populations. Clusters reported (e.g., Druze Arab families) point to shared ancestry. europepmc.org

10. Consanguinity. Increases the chance of inheriting the same rare variant from both parents. academic.oup.com

11. Modifier genes of enamel formation. Background variation in enamel genes may influence how severe the teeth look (hypothesis consistent with variability). ncbi.nlm.nih.gov

12. Modifier genes of skeletal growth. Genetic background can soften or worsen spine/hip findings. ncbi.nlm.nih.gov

13. ECM remodeling imbalance. Without proper LTBP3-TGF-β docking, matrix turnover is abnormal. academic.oup.com

14. Abnormal angiogenesis/vascular wall matrix. TGF-β dysregulation may explain aortic root dilation in a subset. ncbi.nlm.nih.gov

15. Tooth eruption pathway disruption. Enamel and supporting tissues develop abnormally, delaying eruption. MDPI

16. Craniofacial growth effects. Matrix and signaling issues can contribute to malocclusion/crowding. MDPI

17. Hip development alignment shift (coxa valga). Growth plate signaling alters femoral neck angle. rarediseases.info.nih.gov

18. Spinal alignment stress. Flattened vertebrae predispose to scoliosis with growth. rarediseases.info.nih.gov

19. Tooth fragility and wear from absent enamel. Direct material loss drives sensitivity and fractures. MDPI

20. Caries risk from exposed dentin. Thin enamel exposes dentin, raising decay risk even with normal hygiene. MDPI

Symptoms and signs

1. Short trunk with mild short stature. The torso looks shorter than average; legs may appear relatively longer. rarediseases.info.nih.gov

2. Back curvature (scoliosis). A sideways spinal curve may develop in childhood or adolescence. rarediseases.info.nih.gov

3. Back pain or fatigue with activity. Flattened vertebrae can change mechanics and cause discomfort (severity varies). rarediseases.info.nih.gov

4. Broad pelvis/hip shape. Imaging often shows broad ilia; sometimes noticed as hip alignment differences. rarediseases.info.nih.gov

5. Coxa valga. Outward hip angle that may affect gait or posture, often found on X-ray. rarediseases.info.nih.gov

6. Dental enamel that looks very thin or “missing.” Teeth can look small, yellow-brown, or rough because enamel is hypoplastic. MDPI

7. Tooth sensitivity. Hot, cold, and sweet foods may cause pain because dentin is uncovered. MDPI

8. Frequent cavities (caries). Weakened surfaces decay easily if not protected early. MDPI

9. Tooth chipping and wear. Edges fracture with normal chewing due to poor enamel. MDPI

10. Delayed tooth eruption or retained baby teeth. Eruption timing can be irregular. MDPI

11. Malocclusion/crowding. Irregular tooth positions and bite issues may develop. MDPI

12. Short stature compared with peers. Not always severe, but height is often below average. ncbi.nlm.nih.gov

13. Heart valve “clicks” or murmurs (subset). A minority have mitral valve prolapse or similar findings. ncbi.nlm.nih.gov

14. Aortic root enlargement (subset). Usually silent; found only on imaging; important because of long-term risk. ncbi.nlm.nih.gov

15. Family history in siblings (recessive pattern). Especially when parents are related. academic.oup.com

Diagnostic tests

Physical examination (bedside)

1. General growth and body proportions. The doctor measures height and compares trunk vs. leg length to document short-trunk pattern. rarediseases.info.nih.gov

2. Spine inspection and Adam’s forward bend. Looking for rib hump or curve suggests scoliosis that needs imaging. rarediseases.info.nih.gov

3. Gait and hip range-of-motion check. Subtle gait changes can reflect coxa valga or pelvic width differences. rarediseases.info.nih.gov

4. Oral exam of enamel. The dentist assesses enamel thickness, color, surface, and sensitivity across baby and adult teeth. MDPI

Manual / chairside assessments

5. Dental percussion and cold test. Gentle tapping and cold stimuli help judge tooth vitality and dentin exposure/sensitivity. MDPI

6. Bite/occlusion recording. Recording how upper and lower teeth meet helps plan protective restorations. MDPI

7. Scoliosis angle estimation (scoliometer). A quick clinic tool to estimate rotation before definitive imaging. rarediseases.info.nih.gov

Laboratory and pathological / genetic

8. Targeted LTBP3 gene sequencing. Looks for pathogenic variants; confirms the diagnosis. academic.oup.com

9. Exome/genome sequencing. Useful when targeted testing is negative or when multiple genes are considered. academic.oup.com

10. Segregation testing in parents/siblings. Shows the recessive inheritance pattern (each parent is typically a carrier). academic.oup.com

11. mRNA/splicing studies (select cases). If a variant may affect splicing, RNA tests can prove the mechanism. MDPI

12. Cardiac biomarkers (when indicated). Usually normal; ordered only if symptoms suggest cardiac involvement—imaging is primary. ncbi.nlm.nih.gov

Electrodiagnostic / physiologic

13. Electrocardiogram (ECG). Screens heart rhythm when valve disease or aortic dilation is suspected or if symptoms occur. ncbi.nlm.nih.gov

PMC+2sciencedirect.com+2

Safer, evidence-guided “regenerative-adjacent” adjuncts your team may discuss (not curative):

1. Self-assembling peptide scaffolds (experimental/adjunctive use in lesions) — aim to nucleate mineral; clinical protocols limited. dentaljournal.net

2. Biomimetic hydrogels for remineralization (research stage) — lab/early clinical exploration to mimic enamel matrix. sciencedirect.com

3. Amelogenin-related approaches (research) — protein-guided enamel crystal growth under study. PubMed

4. ACP-based systems — clinically used as topical adjuncts for sensitivity and early lesions. SpringerLink

When to see doctors

Seek care promptly for: tooth pain or sensitivity that limits eating/sleep, broken restorations, gum swelling/bleeding, fever or facial swelling (possible infection), difficulty brushing due to pain, visible rapid tooth wear, new or worsening back pain or posture changes, signs of brace intolerance, or any chest pain/shortness of breath or family history suggestive of valve/aortic disease. Routine follow-up with pediatric dentist/restorative dentist, orthodontist, physiotherapist, orthopedist/spine clinic, and medical genetics is recommended; cardiology if indicated. PMC+2BioMed Central+2

What to eat & what to avoid

Eat more of:
• Dairy or fortified alternatives for calcium; balanced protein; fibrous fruits/vegetables; water as main drink. Why: Supports general and oral health without extra acid/sugar load. aapd.org

Avoid/limit:
• Frequent sugary snacks and sticky sweets; acidic drinks (sodas, sports/energy drinks, citrus sips through the day); very hard foods that crack fragile enamel; constant grazing; alcohol and tobacco exposure in household. Why: These increase demineralization, erosion, and mechanical damage to AI teeth. Rinse with water if exposed to acids. aapd.org

Frequently asked questions (FAQs)

1) Is there a cure for brachyolmia–AI?
Not yet. Care is protective and symptom-focused; research is exploring enamel regeneration and biomimetic approaches. PMC

2) What gene is commonly involved?
Bi-allelic LTBP3 variants are strongly linked to this combined skeletal-dental picture (Dental Anomalies and Short Stature, DASS). europepmc.org

3) Will fluoride fix missing enamel?
Fluoride does not regrow enamel, but it strengthens remaining mineral and reduces cavities and sensitivity—cornerstone care. FDA Access Data

4) Are fluoride varnishes medicine or devices?
Many varnishes are FDA-cleared devices, while anticaries dentifrices/rinses follow the OTC anticaries drug monograph; your dentist selects appropriately. FDA Access Data+1

5) Do scoliosis-specific exercises help?
Guidelines support PSSE and bracing in selected patients to reduce progression and improve function/quality of life. BioMed Central

6) When is bracing considered?
Commonly in growing patients with moderate curves; details depend on degree and risk of progression. Dove Medical Press

7) When is surgery for scoliosis needed?
If bracing fails or curves are severe/progressive, spinal surgery may be advised. srs.org

8) Which pain reliever is safer—ibuprofen or acetaminophen?
Both are options; ibuprofen carries GI/cardiovascular/renal warnings; acetaminophen risks liver toxicity if overdosed. Follow labels and clinician advice. FDA Access Data+1

9) Are antibiotics always needed for dental pain?
No. Use only for bacterial infections with signs like swelling/fever or spreading cellulitis; dentist will decide. FDA Access Data

10) Can enamel be regenerated with stem cells now?
