Arterial Tortuosity Syndrome (ATS)

Arterial Tortuosity Syndrome (ATS) is a rare, inherited connective-tissue condition where many large and medium arteries become extra long and twisty (tortuous). Because the ends of each artery are fixed in place in the body, the extra length makes the vessels curve, loop, and sometimes narrow (stenosis) or balloon out (aneurysm). People may also have soft, stretchy skin, flexible joints, hernias, and certain facial features. ATS usually appears in childhood and is passed in families in an autosomal recessive way (a child inherits two non-working copies of the same gene). The main medical risks are vessel narrowing or aneurysm formation that can affect blood flow and raise the chance of complications if not monitored and treated. MedlinePlus+3NCBI+3GARD Information Center+3

ATS is caused by changes (variants) in a gene called SLC2A10, which provides the instructions for a protein nicknamed GLUT10. GLUT10 likely moves vitamin C (ascorbate) inside certain cell compartments where collagen and elastin are made. When GLUT10 does not work, the elastic parts of artery walls are built poorly. This makes arteries longer, more fragile, and more likely to twist or dilate. The TGF-β signaling pathway is often more active in ATS tissues, which may be a reaction to the weak matrix. Together, these changes explain the vessel tortuosity, narrowing, and aneurysms seen in ATS. Oxford Academic+3PubMed+3MedlinePlus+3

Arterial Tortuosity Syndrome, often shortened to ATS, is a rare, inherited connective-tissue condition. In ATS, many medium- and large-sized arteries (including the aorta) become longer than usual and twist or curve more than normal (this is called tortuosity). Some artery segments may also become narrow (stenosis), while others may balloon (aneurysm) or rarely tear (dissection). Because arteries carry blood from the heart to the body, these changes can raise the risk of high blood pressure in the lungs (pulmonary hypertension), poor blood flow to organs, aneurysms, or dissections. People with ATS often have other connective-tissue signs, such as soft or stretchy skin, joint looseness, hernias, and certain facial features. ATS is autosomal recessive, which means a child is affected when they inherit a pathogenic change in both copies of the same gene from their parents. The known cause is harmful variants in SLC2A10, the gene that makes a transporter protein called GLUT10. GLUT10 is involved in how cells handle vitamin-C–related redox balance and growth signals (including TGF-β), which affects how elastic and collagen fibers are built and maintained in artery walls.

Other names

• Arterial tortuosity syndrome (preferred name)

• ATS (abbreviation)

• SLC2A10-related connective-tissue disorder (molecular description)

• GLUT10 deficiency (functional description used in research papers) NCBI+2MedlinePlus+2

Note: ATS is distinct from better-known conditions with arterial problems (such as Loeys–Dietz syndrome or Marfan syndrome). Those have different genes and clinical patterns, even though some features overlap. NCBI

Types

There are no official medical subtypes of ATS. Doctors usually describe ATS by the main blood-vessel pattern and the age when problems first appear:

1. Pulmonary-artery–predominant ATS – tortuosity plus branch pulmonary artery stenosis is the major early issue (often in infants/children). NCBI

2. Aortic-predominant ATS – marked tortuosity/elongation of the aorta with or without aneurysm/dissection risk. NCBI

3. Widespread medium-artery ATS – twisting and lengthening in many medium-sized arteries (neck, abdominal, limb vessels), sometimes with organ ischemia. GIM Journal

4. Early-onset severe presentation – significant vascular disease in infancy/early childhood, often with hernias, diaphragmatic hernia, or facial features. NCBI

5. Later-detected/attenuated presentation – diagnosis in adolescence or adulthood when imaging for another reason reveals tortuosity. ScienceDirect

These labels help talk about patterns but do not change the underlying diagnosis (all are SLC2A10-related ATS).

Causes

Primary genetic cause

1. Biallelic pathogenic variants in SLC2A10 (GLUT10) – this is the core cause of ATS. Both gene copies must carry a disease-causing change. MedlinePlus+1

Pathway-level mechanisms (how the gene change leads to disease)

2. GLUT10 dysfunction – the GLUT10 protein does not transport dehydroascorbic acid (oxidized vitamin C) normally inside cells, disturbing redox balance in key cell compartments. Oxford Academic+1

3. Abnormal TGF-β signaling – disturbed redox and matrix biology can lead to overactive or altered TGF-β pathways, which drive abnormal vessel wall remodeling. MedlinePlus+2PMC+2

4. Elastin/collagen fiber maturation problems – impaired cross-linking and assembly weaken the elastic parts of artery walls, making them prone to twisting, narrowing, or ballooning. PMC+1

5. Vascular smooth-muscle cell stress – oxidative and metabolic stress in artery muscle cells contributes to abnormal vessel shape and stiffness. PMC

Inherited-risk contexts

6. Autosomal recessive inheritance – risk is highest when both parents are carriers. Each pregnancy has a 25% chance of ATS. (Genetic principle summarized in GeneReviews.) NCBI

7. Consanguinity – parents who are related are more likely to carry the same rare variant, increasing the chance of an affected child. NCBI

8. Founder variants in some populations – certain regions/families may share the same ancestral SLC2A10 variant. (Reported across case series.) GIM Journal

Modifiers (do not cause ATS by themselves, but can worsen vascular risk once ATS is present)

9. High blood pressure – more stress on artery walls increases risk of aneurysm or dissection. (General vascular principle; emphasized in ATS care notes.) actionability.clinicalgenome.org

10. Rapid growth spurts/adolescence – changing hemodynamics may unmask stenoses or aneurysm growth. NCBI

11. Pregnancy – higher blood volume and pressure can add risk; careful monitoring is advised. NCBI

12. Smoking or second-hand smoke – harms vascular elastic tissue and raises BP. (General vascular risk; applied in ATS counseling.) actionability.clinicalgenome.org

13. Uncontrolled asthma or lung disease – can raise pulmonary pressures, worsening branch pulmonary artery stenosis effects. NCBI

14. Heavy isometric strain (e.g., max-effort weight-lifting without supervision) – acute BP spikes can stress the aorta/arteries. (General aortopathy guidance.) actionability.clinicalgenome.org

15. Fluoroquinolone antibiotics (class risk for aortic events) – generally avoided in heritable aortopathies unless no alternatives. (Applied from aortopathy safety practices.) actionability.clinicalgenome.org

16. Untreated sleep apnea – surges in nocturnal BP may add risk. (General aortic disease counseling.) actionability.clinicalgenome.org

17. Poor blood-pressure control during surgery/anesthesia – transient surges may stress vessels; specialized peri-operative planning is used. actionability.clinicalgenome.org

18. Severe infections – fever/pain can raise BP and heart rate; careful monitoring is prudent. actionability.clinicalgenome.org

19. Low dietary vitamin C – does not cause ATS, but profound deficiency could, in theory, further impair collagen/elastin handling; healthy, balanced intake is encouraged. (Mechanistic inference from GLUT10/ascorbate literature.) Oxford Academic+1

20. Delay in surveillance – missing scheduled imaging can allow silent aneurysms or stenoses to progress before symptoms appear. NCBI

Symptoms and signs

Symptoms can vary widely and depend on which arteries are affected and how severe the changes are. Many children are diagnosed in infancy or early childhood; some people are diagnosed later.

1. Breathing or feeding trouble in infants – may be due to branch pulmonary artery stenosis or other airway/vascular issues. NCBI

2. Poor weight gain or tiring easily – can reflect limited blood flow or heart-lung strain. National Organization for Rare Disorders

3. Chest pain or chest tightness (older children/adults) – uncommon but important; may relate to aortic problems or high pulmonary pressures. actionability.clinicalgenome.org

4. Dizziness, fainting, or headaches – can result from reduced blood flow through tortuous or narrowed arteries. National Organization for Rare Disorders

5. High blood pressure in the lungs (pulmonary hypertension) – from multiple pulmonary artery narrowings. BioMed Central

6. Murmurs or abnormal heart sounds – from altered flow across narrowed segments. e-cvia.org

7. Aneurysm or dissection (may be silent) – dangerous ballooning or tears in the aorta or other arteries; sometimes present with sudden severe pain. actionability.clinicalgenome.org

8. Soft, mildly stretchy skin; easy bruising – connective-tissue features frequently reported. NCBI

9. Joint hypermobility – increased range of motion in some joints. NCBI

10. Hernias (inguinal, umbilical, diaphragmatic) – due to weaker connective tissue in body walls/diaphragm. NCBI

Diagnostic tests

A) Physical examination

1. General connective-tissue exam – doctor looks for soft/stretchy skin, easy bruising, atrophic scars, hernias, tall or thin habitus, chest-wall or spine shape. These clues support a heritable connective-tissue disorder such as ATS. NCBI

2. Pulse and blood-pressure checks in arms/legs – differences may suggest stenosis or unusual vessel paths. NCBI

3. Cardiac auscultation (listening for murmurs) – flow murmurs can point to pulmonary artery or aortic narrowing. e-cvia.org

4. Respiratory assessment – signs of pulmonary hypertension or recurrent chest infections in infants may appear. BioMed Central

5. Eye and skeletal screening – looking for keratoconus, scoliosis, or pectus helps document the broader phenotype. BioMed Central

B) Manual/bedside tests

6. Beighton score for joint hypermobility – a simple set of maneuvers scores joint laxity, which often accompanies ATS. NCBI

7. Ankle-brachial index (ABI) – compares leg vs arm blood pressures; a low ABI suggests peripheral arterial narrowing or tortuosity. (Applied vascular principle.) actionability.clinicalgenome.org

8. Pulse oximetry (rest/exertion) – low oxygen saturation or drops with activity may point to pulmonary vascular disease. BioMed Central

9. Bedside Doppler (handheld) – quick assessment of blood-flow signals in accessible arteries can suggest stenosis before full imaging. NCBI

10. Orthostatic vitals – BP/HR changes when standing may unmask limited flow in tortuous vessels (supportive, not diagnostic). actionability.clinicalgenome.org

C) Laboratory and pathological tests

11. Molecular genetic testing of SLC2A10 – confirms the diagnosis by finding pathogenic variants in both copies of the gene. Testing may start with sequencing and add deletion/duplication analysis if needed. Parental testing clarifies carrier status. NCBI+1

12. Targeted variant testing in relatives – used when a family’s specific SLC2A10 variants are known, for carrier or prenatal testing. NCBI

13. Basic labs (CBC, BMP, lipids) – do not diagnose ATS but help manage blood-pressure risks and surgical planning. (Care practice.) actionability.clinicalgenome.org

14. Biopsy/histology (rarely needed) – research series show fragmented elastic fibers and matrix changes, but this is not routine for diagnosis. GIM Journal

15. Pregnancy-related labs – if pregnant, routine labs plus careful BP monitoring help assess maternal–fetal risk in ATS. NCBI

D) Electrodiagnostic and physiologic tests

16. Electrocardiogram (ECG) – evaluates heart rhythm/strain that can result from pulmonary hypertension or valve/flow issues. BioMed Central

17. Ambulatory BP monitoring – detects masked or nighttime hypertension that can stress arteries. (Aortopathy care principle.) actionability.clinicalgenome.org

18. Cardiopulmonary exercise testing (selected centers) – measures exercise capacity and oxygen delivery; can uncover pulmonary vascular limits. BioMed Central

E) Imaging tests

19. Echocardiography – first-line to look at the aortic root, heart function, pulmonary pressures, and proximal pulmonary arteries. Repeated over time for surveillance. NCBI

20. CT angiography (CTA) – detailed 3-D look at tortuosity, stenoses, aneurysms, and the whole aorta/arterial tree; used carefully due to radiation/contrast. AHA Journals

21. MR angiography (MRA) – radiation-free 3-D mapping of arteries; excellent for serial surveillance of the aorta and branches. NCBI

22. Doppler ultrasound – noninvasive flow study for neck, abdominal, renal, or limb arteries, and for branch pulmonary arteries in some centers. NCBI

23. Chest CT (non-contrast as needed) – shows airways, lungs, and mediastinum and may incidentally show tortuous great vessels. e-cvia.org

24. Brain/neck MRA or CTA – screens for intracranial or cervical artery tortuosity/aneurysm if symptoms or family pattern suggest risk. actionability.clinicalgenome.org

25. Whole-aorta protocol (head-to-pelvis) by CTA/MRA – periodic comprehensive mapping recommended in many aortopathies; adapted to ATS based on age and findings. actionability.clinicalgenome.org

Non-pharmacological treatments (therapies & others)

Important note: There is no proven disease-specific medicine or lifestyle cure for ATS. Most care aims to monitor arteries, reduce hemodynamic stress, manage complications, and support general health. Items below reflect expert practice for rare connective-tissue arteriopathies and ATS case literature.

1. Lifelong vascular surveillance program. Create an imaging plan (echo + targeted CTA/MRA) to map tortuosity, stenoses, and aneurysms at baseline, then re-check on a schedule (e.g., 6–12 months or as advised). Early detection guides safe activity, pregnancy counseling, and timing of any procedure. NCBI

2. Blood-pressure lifestyle control. Use salt moderation, weight management, regular gentle aerobic activity, and stress reduction to keep blood pressure lower, easing wall stress on vulnerable arteries. This complements medication if needed. NCBI

3. Exercise plan: low-impact, no straining. Favor walking, cycling, or swimming. Avoid heavy isometric lifting, high-impact collision sports, and Valsalva-type straining that spikes blood pressure and shear stress. NCBI

4. Respiratory and pulmonary care when branch stenosis exists. Pediatric pulmonary artery stenosis or aortic arch narrowing may cause unequal blood flow. Pulmonology and cardiology teams tailor monitoring and activity. NCBI

5. Cardiac rehabilitation–style coaching (modified). Gentle, supervised conditioning improves fitness without unsafe pressure surges; education helps patients recognize warning symptoms promptly. NCBI

6. Genetic counseling. Explain autosomal-recessive inheritance, 25% recurrence risk for future children when both parents are carriers, and options for family testing and reproductive planning. NCBI+1

7. Pregnancy planning in specialized centers. Pre-pregnancy vascular mapping and multidisciplinary plans (cardiology, MFM, anesthesia) reduce risk; delivery route is individualized based on aortic size, tortuosity, and hemodynamics. NCBI

8. Dental/airway planning. Craniofacial traits, high palate, or joint laxity can influence intubation and dental procedures; alert clinicians to minimize neck strain and blood-pressure surges during anesthesia. NCBI

9. Skin and hernia care. Gentle skin care for soft, extensible skin, early assessment of inguinal/diaphragmatic hernias, and avoidance of sudden strain that can worsen hernias. NCBI

10. Eye surveillance. Screen for keratoconus and corneal thinning; early referral improves options (e.g., cross-linking) and visual outcomes. GARD Information Center

11. Nutrition for vascular health. Emphasize a balanced diet rich in fruits/vegetables and adequate vitamin C from food; avoid extreme supplementation claims. The aim is overall cardiovascular health, not a cure. PubMed

12. Smoking avoidance and second-hand smoke minimization. Smoking raises vascular risk and blood pressure and should be strictly avoided in ATS. NCBI

13. Temperature and dehydration awareness. Prevent dehydration and overheating that can trigger blood-pressure swings and tachycardia; steady hydration supports stable hemodynamics. NCBI

14. Infection prevention and fever control. Fever raises heart rate and can transiently raise hemodynamic stress; prompt treatment and hydration are sensible supportive steps. NCBI

15. Psychological support. Living with a rare disease is stressful. Counseling and patient-support groups improve coping and adherence to monitoring plans. National Organization for Rare Disorders

16. School and workplace accommodations. Provide notes on activity limits (no heavy lifting), hydration breaks, and emergency plans for chest, back, or neurological symptoms. NCBI

17. Safe travel planning. Carry a diagnosis summary, imaging reports, and center contacts; avoid activities that involve extreme straining or remote settings without medical access. NCBI

18. Medication safety review before procedures. Coordinate with anesthesia and surgery teams for blood-pressure targets, vascular access planning, and careful arterial line placement in tortuous vessels. NCBI

19. Vaccinations per guidelines. Keeping up to date lowers infection-related physiologic stress; there is no ATS-specific vaccine rule beyond standard care. NCBI

20. Emergency symptom education. Teach families to act fast for new chest/back pain, fainting, stroke-like symptoms, or limb ischemia signs—these may indicate dissection, critical stenosis, or aneurysm issues. NCBI

Drug treatments

Key reality: There is no medicine proven to reverse ATS or its arterial tortuosity. Treatment is symptom- and complication-directed, often borrowing principles from other heritable arteriopathies (e.g., Marfan, Loeys–Dietz) while acknowledging limited ATS-specific trial data.

I group the medications by purpose, keeping details simple and practical.

1) Antihypertensives (general).
Class & purpose: ACE inhibitors, ARBs, beta-blockers, calcium-channel blockers—used to keep blood pressure in a safe, low range to reduce stress on fragile arteries. Timing & dose: individualized to age, weight, and targets; titrate slowly. Mechanism: lower systemic pressure and/or blunt heart rate/sheer forces. Side effects: dizziness, fatigue, electrolyte shifts; monitor kidney function and symptoms. Evidence is extrapolated; still, careful BP control is standard. NCBI

2) Beta-blockers (e.g., atenolol, metoprolol).
Purpose: reduce heart rate and pulse pressure to ease wall stress. Mechanism: block β-adrenergic receptors, lowering contractility and rate. Dosing/time: daily; pediatric dosing by weight. Risks: fatigue, cold extremities, asthma worsening. Used widely in connective-tissue aortopathies; ATS-specific trial data are lacking. NCBI

3) ARBs (e.g., losartan).
Purpose: blood-pressure reduction; theoretical benefit on TGF-β signaling (shown in other syndromic aortopathies). Mechanism: block angiotensin II type 1 receptor; may secondarily modulate TGF-β tone. Dosing: once daily; titrate to BP goals. Risks: dizziness, high potassium, renal effects. In ATS, robust outcome data are not established; use is individualized. MedlinePlus

4) ACE inhibitors (e.g., enalapril).
Purpose/mechanism: reduce angiotensin II production; lower BP and afterload. Use: an option if ARB not tolerated. Risks: cough, high potassium, rare angioedema; monitor labs. Evidence base in ATS itself is limited. NCBI

5) Calcium-channel blockers (e.g., amlodipine).
Purpose: alternative or add-on for BP and vasospasm management. Mechanism: relax vascular smooth muscle. Risks: ankle swelling, flushing, gingival changes. Choose based on patient profile. NCBI

6) Thiazide diuretics (e.g., hydrochlorothiazide).
Purpose: gentle BP aid; helpful if volume sensitive. Mechanism: increase renal sodium/water excretion. Risks: low potassium, gout flares, photosensitivity; watch electrolytes. NCBI

7) Short-term antiplatelet therapy (when indicated).
Use case: select post-procedure settings (e.g., stent or graft) or specific vascular events per specialist advice. Risks: bleeding/bruising; not for routine prophylaxis without indication. NCBI

8) Anticoagulation (case-by-case).
Use case: if thrombosis risk is present (e.g., documented clot, certain post-surgical states). Risks: bleeding; must balance carefully in fragile vessels. NCBI

9) Pain control strategy.
Goal: treat chest/back pain cautiously—pain can mask serious events. Prefer acetaminophen first; use NSAIDs or opioids only with clinician guidance. Risks: NSAIDs may affect BP/renal function. NCBI

10) Statins (selected adults with dyslipidemia).
Purpose: standard atherosclerotic risk reduction if lipid criteria met; not ATS-specific. Mechanism: lower LDL; stabilize plaques. Risks: myalgias, liver enzyme elevation. NCBI

11) Peri-anesthesia BP/HR control meds.
Use: carefully chosen agents (e.g., esmolol, vasodilators) during procedures to avoid sudden pressure spikes in tortuous/aneurysmal arteries. Risks: hypotension/bradycardia; titrate with monitoring. NCBI

12) Bronchodilators with caution (if asthma).
Note: some raise heart rate; coordinate with cardiology to balance breathing relief with hemodynamic goals. NCBI

13) Headache/vascular migraine care.
Approach: choose agents that don’t sharply raise BP; emphasize hydration and trigger control. Consult if triptans/ergots are considered. NCBI

14) Iron therapy (if anemia).
Why: anemia can increase cardiac output and wall stress; treat confirmed iron deficiency per standard guidelines. NCBI

15) Antibiotics (procedure prophylaxis only if indicated).
Note: No ATS-specific endocarditis rule; follow standard indications for the operation or device involved. NCBI

16) Gastroesophageal reflux treatment (if present).
Reason: reduces cough/strain episodes that may spike intrathoracic pressure. NCBI

17) Sleep-disordered breathing management.
Rationale: treating OSA lowers night-time BP surges and sympathetic tone. NCBI

18) Vaccines/fever control medications.
Use: antipyretics for high fevers to limit tachycardia; follow routine immunization schedules. NCBI

19) Obstetric medications per MFM plan.
Note: BP control and labor analgesia are individualized; avoid sudden hemodynamic swings. NCBI

20) No routine “TGF-β blocker” therapy for ATS.
Reality check: While ARBs (e.g., losartan) have theoretical appeal via TGF-β in other syndromes, ATS-specific outcome data are insufficient; decisions are individualized and evidence-informed. MedlinePlus

Dietary molecular supplements

There is no supplement proven to fix ATS. Food-first nutrition is safest. Avoid “vascular cure” claims. The notes below explain plausible roles and limits.

1. Vitamin C from foods (not megadoses). Because GLUT10 likely moves ascorbate where collagen/elastin are built, healthy dietary vitamin C intake makes sense; megadoses have no proven ATS benefit and can have downsides (e.g., kidney stones). PubMed

2. Balanced omega-3 intake (food sources). Supports general cardiovascular health and lipids; no ATS-specific data. NCBI

3. Magnesium (only if deficient). May help BP modestly in deficiency; test before supplementing. NCBI

4. Potassium-rich foods (unless restricted). Helpful for BP in the general population; avoid if on meds that raise potassium or with renal issues. NCBI

5. Folate and B-vitamins (if low). Correct deficiencies that can affect vascular health; ATS-specific impact unknown. NCBI

6. Vitamin D (if deficient). Supports overall health; deficiency common; ATS-specific benefit unproven. NCBI

7. CoQ10 (evidence limited). Sometimes used for general cardiovascular support; no ATS evidence. Discuss before use. NCBI

8. Plant-based antioxidants (in diet). Emphasize fruits/vegetables rather than pills; supplement trials in ATS don’t exist. NCBI

9. Fiber (dietary). Helps lipids and BP indirectly; universal cardiovascular advice. NCBI

10. Avoid unregulated “vascular” supplements. Many claim collagen/elastin benefits without data and may interact with medicines. NCBI

Immunity-booster / regenerative / stem-cell” drugs

There are no approved regenerative or stem-cell drugs for ATS. Below are clarifications so readers avoid misinformation.

1. Stem-cell therapies: No clinical evidence for ATS; not recommended outside approved research. NCBI

2. Growth-factor injections: Not studied for arterial wall repair in ATS; avoid. NCBI

3. Gene therapy: No approved SLC2A10 therapy; conceptually possible in the future but currently unavailable. NCBI

4. Immune “boosters”: Generic immune tonics do not fix connective-tissue gene defects; be cautious. NCBI

5. TGF-β pathway “blockers”: No proven ATS benefit beyond individualized ARB use; do not self-medicate. MedlinePlus

6. High-dose vitamin C injections: Not an ATS treatment and can be harmful; food-first approach is safest. PubMed

Surgeries

1) Open repair of ascending aortic aneurysm (with graft).
Procedure: Replace the enlarged ascending aorta/hemi-arch with a surgical graft. Why: Prevent rupture or dissection when the aneurysm reaches size/risk thresholds; open repair has durable results in pediatric ATS case reports. PubMed+2Oxford Academic+2

2) Repair of aortic root or arch anomalies.
Procedure: Tailored reconstruction or grafting of dilated or kinked segments. Why: Restore safe flow and reduce wall stress when imaging shows progression or symptoms. Cambridge University Press & Assessment

3) Repair of branch pulmonary artery stenosis.
Procedure: Patch augmentation or other surgical techniques to widen narrowed branches. Why: Improve oxygenation and reduce right-sided heart strain in significant stenoses. NCBI

4) Endovascular stenting—selected cases.
Procedure: Catheter-based stents for focal stenoses in experienced hands. Why: Minimally invasive option in anatomically suitable lesions; however, vessel fragility and growth in children limit routine use. NCBI

5) Hybrid or staged vascular reconstructions.
Procedure: Combine open and endovascular steps for complex multi-segment disease. Why: Personalize risk and durability in tortuous anatomies. NCBI

When to see doctors

Urgent / emergency now: sudden chest or back pain; new shortness of breath; fainting; stroke-like symptoms (weakness, facial droop, speech trouble); cold/pale limb with pain; severe, new headache with neck stiffness. These can signal dissection, critical stenosis, aneurysm complications, or embolic events. Call emergency services. NCBI

Soon (within days): persistent chest discomfort, new exercise intolerance, recurrent dizziness, or blood-pressure readings consistently above targets. These may indicate progression that needs imaging and therapy adjustment. NCBI

Routine (as scheduled): follow-up imaging, blood-pressure checks, genetic counseling, eye exams, and dental care planning. Lifelong surveillance is essential even when you feel well. NCBI

Frequently asked questions

1) Is ATS curable?
No. It’s lifelong. Care focuses on surveillance, BP control, activity adjustments, and procedures when needed. NCBI

2) Which gene is involved?
SLC2A10 (encoding GLUT10). Two non-working copies cause ATS. GARD Information Center

3) What does GLUT10 do?
It likely moves ascorbate into places where collagen/elastin are built; when it fails, artery walls are formed poorly, and TGF-β signaling is upregulated. PubMed+1

4) How is ATS diagnosed?
By clinical findings plus genetic testing showing biallelic SLC2A10 variants; imaging maps the arteries. Orpha

5) What are the main risks?
Arterial stenoses and aneurysms that can lead to reduced blood flow, dissection, or rupture if untreated. NCBI

6) Can children with ATS be active?
Yes—gentle, low-impact exercise is encouraged; avoid heavy straining and collision sports. NCBI

7) Are there proven medicines to stop tortuosity?
No. BP control is standard; ARBs/beta-blockers are used for hemodynamic reasons, not because they’re proven to “fix” ATS. NCBI+1

8) Do supplements help?
