ANO10 Autosomal Recessive Cerebellar Ataxia (SCAR10)

ANO10 autosomal recessive cerebellar ataxia is a rare, inherited brain disorder. It mainly affects the cerebellum, the part of the brain that controls balance, walking, and coordination. It happens when both copies of a person’s ANO10 gene (also known as TMEM16K) carry disease-causing changes. Doctors call this autosomal recessive inheritance. People with this condition usually start to lose balance and coordination in the teenage years or in early adulthood. Over time, speech can become slurred, eye movements can be jerky, and walking becomes more difficult. Brain scans often show shrinkage (atrophy) of the cerebellum. In some people, seizures and problems with thinking or nerves in the limbs can also appear. NCBI+1

SCAR10 is a rare inherited brain disease caused by harmful changes in a gene called ANO10. This gene helps brain cells—especially those in the cerebellum, the “coordination center” at the back of the brain—handle cell-membrane signals and calcium balance. When both copies of ANO10 don’t work, cerebellar cells slowly stop working and shrink. People develop clumsy walking (ataxia), poor balance, shaky or scanning speech, eye movement problems, sometimes numbness in hands/feet (neuropathy), and bladder or mood symptoms. There is no proven cure yet; treatment focuses on safety, function, and quality of life with rehabilitation and symptom control. NCBI

Another names

This condition appears in clinics and papers under several names. All of these point to the same disease linked to ANO10/TMEM16K:

• SCAR10 (Spinocerebellar Ataxia, Autosomal Recessive 10)

• ANO10-related spinocerebellar ataxia

• ATX-ANO10 (a naming style used in some genetic catalogs)

• TMEM16K-related ataxia

• Anoctamin-10–related autosomal recessive cerebellar ataxia

“ANO10” and “TMEM16K” are two names for the same gene/protein; TMEM16K belongs to the anoctamin (TMEM16) family. Orpha.net+1

Types

There is no strict, official subtype list, but doctors see a spectrum. These patterns help describe how the illness looks in real life:

1. Classic late-teen/young-adult onset cerebellar ataxia
   The most common picture: slowly worsening gait and limb incoordination, slurred speech, and abnormal eye movements; MRI shows cerebellar atrophy. NCBI

2. Ataxia with seizures
   Some patients develop epileptic seizures after ataxia begins. Seizure risk varies across families. NCBI

3. Ataxia with peripheral nerve involvement
   Some have numbness, tingling, or reduced reflexes suggesting peripheral neuropathy. PMC

4. Ataxia with cognitive or psychiatric features
   A minority show mild cognitive problems or mood/behavior changes. Myriad Genetics

5. Possible CoQ10-responsive subgroup
   A few reported patients had low coenzyme Q10 (CoQ10) in muscle and modest clinical benefit from CoQ10 supplements. This is not universal. NCBI

These patterns reflect how disease-causing ANO10 variants can lead to slightly different problems in different people. PMC

Causes

“Causes” here explains why the disease happens and what goes wrong in cells. All are tied to disease-causing variants (mutations) in ANO10/TMEM16K:

1. Biallelic ANO10 pathogenic variants (missense, nonsense, frameshift, or splice) reduce or remove protein function; this is the root cause. PMC

Symptoms

Symptoms can vary. They usually build up slowly over years.

1. Unsteady walking (gait ataxia)—bumping into things or needing wide-based steps. NCBI

2. Clumsy hand/arm movements (limb ataxia)—trouble with buttons, keys, or writing. NCBI

3. Slurred or scanning speech (dysarthria)—speech can sound choppy or slow. NCBI

4. Jerky eye movements (nystagmus)—may cause blurred or jumpy vision. NCBI

5. Trouble swallowing (dysphagia)—coughing with liquids or pills. NCBI

6. Poor balance with standing or turning—falls, especially in the dark or on uneven ground. NCBI

7. Seizures in some families—episodes of loss of awareness or shaking. NCBI

8. Abnormal tracking eye movements—difficulty keeping eyes on a moving target. NCBI

9. Mild thinking or memory problems in a subset of patients. Myriad Genetics

10. Peripheral nerve symptoms—numbness, tingling, or reduced reflexes. PMC

11. Tremor—shaking of the hands during action. (Reported in case series of recessive ataxias.) PMC

12. Leg stiffness or brisk reflexes (pyramidal signs) in some individuals. thejcn.com

13. Fatigue—walking and talking can take more effort. (Common in progressive ataxias.) NCBI

14. Slow saccades or gaze-holding difficulty—eye movement control is impaired. NCBI

15. Anxiety or low mood—a possible reaction to chronic disability; sometimes part of the neurologic picture. (General ataxia literature.) NCBI

Diagnostic tests

Doctors combine history, examination, blood tests, brain imaging, nerve tests, and genetic testing. Below I group tests by category. Each item includes what it is and why it helps.

A) Physical exam (at the bedside)

1. Neurologic gait assessment
   The doctor watches how you walk, turn, and stand. A wide-based, unsteady gait suggests cerebellar ataxia. This is the first clue in SCAR10. NCBI

2. Finger-to-nose and heel-to-shin testing
   You touch your nose with a finger and slide your heel down the opposite shin. Overshoot or wobble points to limb ataxia. NCBI

3. Eye movement exam
   The doctor checks for nystagmus, slow saccades, and poor tracking. Eye signs are common in ANO10-related ataxia. NCBI

4. Speech and swallowing assessment
   Listening for scanning speech and asking about choking episodes helps document dysarthria and dysphagia. NCBI

5. Strength, tone, and reflexes
   Brisk reflexes or spastic tone point to pyramidal signs; reduced reflexes suggest peripheral neuropathy. Either pattern can appear in some patients. thejcn.com

B) Manual/bedside functional tests

6. Romberg test
   You stand with feet together, eyes open then closed. More sway or falls with eyes closed suggests a proprioceptive or cerebellar problem and helps quantify balance difficulty. NCBI

7. Tandem (heel-to-toe) gait
   Walking heel-to-toe in a straight line stresses balance; failure supports a cerebellar ataxia diagnosis. NCBI

8. Rapid alternating movements (dysdiadochokinesia)
   You flip your hands quickly back and forth. Slowness or irregular rhythm indicates cerebellar dysfunction. NCBI

9. Rebound phenomenon (Holmes test)
   The examiner suddenly releases resisted elbow flexion; an overshoot indicates poor cerebellar “checking” of movement. Helpful to document severity. NCBI

10. Scale for the Assessment and Rating of Ataxia (SARA) or ICARS
    Standardized bedside scores track disability over time and help in trials. NCBI

C) Lab and pathological tests (blood, muscle, or DNA)

11. Targeted next-generation sequencing (NGS) ataxia panel including ANO10
    This confirms the diagnosis by finding two disease-causing variants in ANO10/TMEM16K. It is the gold standard for a precise genetic answer. PMC

12. Whole-exome or whole-genome sequencing
    Used if a panel is negative or to clarify uncertain variants; also helps discover new or rare ANO10 changes. American Academy of Neurology

13. Serum Coenzyme Q10 (CoQ10) or muscle CoQ10
    A few patients with SCAR10 show low CoQ10 levels; identifying this may guide a trial of supplementation. NCBI

14. Rule-out blood work
    Tests for treatable ataxia mimics (vitamin E, B12, thyroid, glucose, celiac antibodies, copper, autoimmune screens) ensure nothing else is causing or worsening symptoms. (General hereditary ataxia workup.) NCBI

15. Pathology (rarely needed)
    Muscle biopsy may be considered if mitochondrial disease or CoQ10 deficiency is strongly suspected; usually genetics makes biopsy unnecessary in SCAR10. NCBI

D) Electrodiagnostic tests

16. EEG (electroencephalogram)
    If seizures are suspected, EEG records brain waves to detect epileptic activity. Seizures are reported in a subset of SCAR10 families. NCBI

17. Nerve conduction studies and EMG
    These tests look for peripheral neuropathy (reduced nerve signal size or speed). Some SCAR10 patients show neuropathic features. PMC

18. Evoked potentials (VEP/SSEP)
    These measure how fast signals travel in vision and sensory pathways. They can uncover subclinical pathway delays seen in cerebellar disorders. (General ataxia testing.) NCBI

E) Imaging tests

19. Brain MRI
    MRI often shows cerebellar atrophy (shrinkage). This supports a cerebellar disorder and helps exclude other causes such as tumors, strokes, or multiple sclerosis. NCBI

20. MR spectroscopy or volumetry (if available)
    These research or advanced tools can quantify cerebellar volume loss or metabolic changes and help track progression in studies. (General hereditary ataxia imaging.) NCBI

Non-pharmacological treatments

1. Task-specific Physiotherapy (intensive, balanced program).
   Purpose: Improve walking, balance, and daily safety.
   Mechanism: Repeated, goal-directed practice drives motor learning in remaining cerebellar and extra-cerebellar networks. Programs blend gait training, balance challenges, coordination drills, treadmill/body-weight support, and home exercise. Evidence in degenerative ataxias shows clinically meaningful gains in walking speed, balance scores, and activities—especially with multi-week, intensive blocks followed by maintenance. Start early; dose matters (multiple hours per week). Structured cues, metronome pacing, and dual-task practice can reduce falls. Add ankle/foot orthoses only if ankle instability is large; otherwise they may dampen needed feedback. PMC

2. Occupational Therapy (OT) for activities of daily living.
   Purpose: Keep independence in dressing, eating, writing, computer use, and work.
   Mechanism: OT breaks tasks into safe steps, recommends adaptive tools (weighted utensils, non-slip mats, button hooks, pen grips), and trains energy conservation and home modifications (grab bars, railings, seated tasks). This reduces falls and caregiver burden and lets people keep roles at home or work longer. OT also teaches “compensatory” strategies—slowing down, wider stance, and using vision to guide hand control—to bypass the timing errors of cerebellar control. Ataxia UK

3. Speech Therapy for Ataxic Dysarthria (voice, pacing, clarity).
   Purpose: Make speech more understandable and reduce fatigue.
   Mechanism: Therapists train breath support, voice loudness, over-articulation, and pacing (e.g., syllable segmentation). Programs adapted from Parkinson therapies (e.g., high-effort voice) can help some ataxias, though effects vary; the principle is intensive, repetitive practice with feedback to stabilize timing. Early referral prevents social withdrawal. National Ataxia Foundation+1

4. Swallowing Therapy & Dysphagia Safety Plan.
   Purpose: Prevent choking/aspiration pneumonia and maintain nutrition/hydration.
   Mechanism: After a clinical and, if needed, instrumental study (FEES or VFSS), speech-language pathologists prescribe posture changes, swallow exercises, and texture modifications that match the person’s specific impairment; thickened liquids are used only when indicated by testing. Regular re-checks adjust the plan as disease changes. ASHA Apps+1

5. Vision & Oculomotor Rehabilitation.
   Purpose: Reduce dizziness, oscillopsia, and reading fatigue.
   Mechanism: Therapists target smooth pursuit, saccades, gaze-holding, and visual substitution strategies. Combining eye exercises with balance work improves navigation and reduces falls when eye movement control is impaired by cerebellar dysfunction. PMC

6. Fall-prevention & Home Safety Program.
   Purpose: Cut fracture and head-injury risk.
   Mechanism: Hazard removal (loose rugs, cords), better lighting, grab bars, shower chairs, footwear audits, and caregiver training. PT adds reactive balance practice and safe turning. These environmental and behavioral changes complement training gains and protect quality of life. PMC

7. Energy Conservation & Fatigue Management.
   Purpose: Make limited energy last across the day.
   Mechanism: OT teaches pacing, task clustering, sitting for tasks, and using mobility aids for long distances. Managing orthostatic symptoms and sleep hygiene also reduces fatigue “amplifiers.” Ataxia UK

8. Bladder Strategies & Pelvic-floor Therapy.
   Purpose: Reduce urgency, frequency, and incontinence that can accompany ataxias.
   Mechanism: Timed voiding, fluid timing, pelvic-floor exercises, and (if needed) referral for urologic evaluation and targeted therapies. This program decreases falls (night-time rushing) and improves sleep. Ataxia UK

9. Respiratory & Airway Protection Training.
   Purpose: Support cough strength and protect lungs when coordination is poor.
   Mechanism: Assisted cough techniques, breath-stacking, and posture education reduce pneumonia risk when swallow inefficiency or weak cough is present. PMC

10. Cognitive-behavioral therapy (CBT) & Mental-health care.
    Purpose: Treat depression/anxiety that commonly follow progressive neurologic disease and worsen disability.
    Mechanism: CBT reframes catastrophic thinking, builds coping routines, and improves adherence to rehab. Combined with SSRIs when indicated, it improves participation and sleep. continuum.aan.com

11. Non-invasive Brain Stimulation (research/adjunct).
    Purpose: Explore symptomatic relief in trials.
    Mechanism: Small studies of cerebellar tDCS or rTMS try to modulate cerebellar-cortical circuits to improve timing and balance. These are investigational; enroll via clinical trials. MDPI+1

12. Education & Multidisciplinary Care Pathways.
    Purpose: Coordinate neurology, rehab, nutrition, speech, urology, and mental-health care.
    Mechanism: Using structured guidelines for progressive ataxias improves timely referral, equipment choice, and complication prevention, reducing hospitalizations. Ataxia UK

Dietary molecular supplements

(Nutrition supports health; supplements do not cure SCAR10. Discuss with a clinician—interactions are common. Doses below reflect typical ranges used in research/clinical practice references for general health contexts.)

1. Coenzyme Q10 (Ubiquinone/Ubiquinol).
   Dose: 100–300 mg/day with food (fat-containing meal).
   Function/mechanism: Mitochondrial electron-transport cofactor and antioxidant; supports cellular energy. Limited neurologic evidence; sometimes tried in ataxias for fatigue or general energy, but not disease-modifying. Watch for interactions with anticoagulants. NCCIH+1

2. Vitamin E (α-tocopherol).
   Dose: Only if deficient; avoid high-dose chronic use unless directed (bleeding risk).
   Function/mechanism: Antioxidant for lipid membranes. High doses can raise hemorrhagic stroke risk; use targeted repletion guided by labs. Office of Dietary Supplements

3. Vitamin D3 (cholecalciferol).
   Dose: Individualize to reach 25-OH-D sufficiency (often 800–2000 IU/day; lab-guided).
   Function/mechanism: Bone, muscle, and immune support; prevents fractures alongside fall-reduction programs. Avoid excessive dosing. Office of Dietary Supplements

4. Vitamin B1 (Thiamin).
   Dose: Diet repletion or 50–100 mg/day short-term if low risk suspected; lab-guided.
   Function/mechanism: Coenzyme in carbohydrate metabolism; deficiency worsens neuropathy and fatigue. Office of Dietary Supplements

5. Vitamin B12 (Cobalamin).
   Dose: Oral 1000 mcg/day or periodic injections if malabsorption; lab-guided.
   Function/mechanism: Myelin and DNA synthesis; deficiency causes neuropathy and anemia—treating deficiency prevents added neurologic burden. Office of Dietary Supplements

6. Omega-3 fatty acids (EPA/DHA).
   Dose: 1–2 g/day combined EPA+DHA (from food or supplements) unless contraindicated.
   Function/mechanism: Anti-inflammatory lipid mediators; general cardiovascular support that is valuable in chronic neurologic illness. Office of Dietary Supplements

7. Magnesium.
   Dose: 200–400 mg elemental/day; select glycinate/citrate for GI tolerance; renal adjust.
   Function/mechanism: Nerve-muscle excitability, sleep quality, constipation relief; correct if dietary intake is low. Office of Dietary Supplements

8. Alpha-lipoic acid (ALA).
   Dose: 300–600 mg/day (common neuropathy studies).
   Function/mechanism: Antioxidant involved in mitochondrial enzyme complexes; evidence mainly in diabetic neuropathy; data in ataxia are limited. NCBI+1

9. Curcumin (from turmeric) — consider food sources over pills.
   Dose: If used, follow product’s lower end and take with food/pepper for absorption; many interactions.
   Function/mechanism: Anti-inflammatory polyphenol; human efficacy is condition-specific and evidence is mixed; focus on culinary use. NCCIH+1

10. General multivitamin-mineral (low-dose).
    Dose: Once daily, not “mega-dose.”
    Function/mechanism: Backstop for borderline intake in chronic illness; choose reputable, third-party-tested products. (See NIH ODS index for evidence and safety overviews.) Office of Dietary Supplements

Immunity boosters, regenerative, and stem-cell drugs

1. There are no FDA-approved stem-cell or regenerative drugs for cerebellar ataxias, including SCAR10. Any clinic promising cures with stem cells/exosomes is outside evidence-based care and may be illegal or unsafe. U.S. Food and Drug Administration

2. Unapproved stem-cell interventions can cause severe harm (infections, blindness, tumors). Avoid commercial offerings; consider only regulated clinical trials at academic centers. U.S. Food and Drug Administration+1

3. Regulatory enforcement is active against marketers of unapproved regenerative products; don’t pay out-of-pocket for these. U.S. Food and Drug Administration

4. If you see news about permissive state laws for stem cells, remember they do not replace FDA approval and do not prove safety/efficacy. Patients remain at risk. WIRED

5. Evidence-informed “immune support” is basic care: vaccination updates, sleep, nutrition, exercise, and management of reflux/aspiration risk—not “immune-booster pills.” These reduce infection-related setbacks that can accelerate disability. (General principle reinforced by dysphagia and aspiration-prevention guidelines.) ASHA Apps

6. Participate in clinical trials (e.g., non-invasive brain stimulation, rehabilitation dosing, or future gene-targeted approaches) through reputable registries/centers. MDPI

---

Surgeries/procedures (when and why)

1. Percutaneous Endoscopic Gastrostomy (PEG) tube.
   Procedure/why: A feeding tube placed through the abdominal wall when swallowing is unsafe or calories are inadequate despite therapy. In neurogenic dysphagia, PEG reduces aspiration, stabilizes weight, and eases medication delivery. Timing is individualized and usually considered when swallowing is unlikely to recover sufficiently—decisions follow instrumental swallow studies and multidisciplinary input. PMC+1

2. Intrathecal Baclofen Pump implantation.
   Procedure/why: A programmable pump placed under the skin delivers baclofen directly into spinal fluid for severe spasticity not controlled by pills or botulinum toxin. It can enhance positioning, hygiene, and comfort—and sometimes mobility—while reducing systemic sedation. Requires regular follow-up; abrupt interruption is dangerous. FDA Access Data+1

3. Spinal fusion for progressive neuromuscular scoliosis (selected cases).
   Procedure/why: If a structural curve progresses and impairs sitting balance, care, or breathing, fusion can improve alignment, seating comfort, and pulmonary mechanics. Risks are meaningful; decisions are individualized in high-risk pathways. PMC+1

4. Focal botulinum injections (repeat every ~3 months).
   Procedure/why: For limb/neck dystonia or focal spasticity causing pain, hygiene problems, or posture issues, targeted injections relax specific muscles without systemic sedation. FDA Access Data

5. Feeding/airway protection adjuncts (e.g., temporary nasogastric tubes, aspiration-prevention measures).
   Procedure/why: Short-term NGT may be used while assessing recovery potential; long-term nutrition generally favors PEG when dysphagia is persistent. SpringerOpen

When to see doctors

• Immediately / same day: choking episodes, fever with cough after swallowing problems (possible aspiration), sudden new weakness or severe dizziness causing repeated falls, fainting on standing, or confusion after medication changes. These can be emergencies and need urgent evaluation for pneumonia, orthostatic hypotension, dehydration, or drug effects. ASHA Apps

• Within 1–2 weeks: noticeable speech decline, new bladder problems, painful spasms that limit care, mood crisis, or unintentional weight loss—these usually benefit from prompt therapy or medication adjustments. ASHA+1

• Routine (every 3–6 months): neurology and rehab check-ins to update therapy goals, equipment, and swallowing plans, plus yearly medication reviews and nutrition labs (vitamin D/B12). Ataxia UK+2Office of Dietary Supplements+2

What to eat & what to avoid

1. Mediterranean-leaning plate: vegetables, fruits, legumes, nuts, whole grains, fish—supports overall cardiometabolic health in chronic neurologic disease. Add omega-3 fish 2–3×/week. Office of Dietary Supplements

2. Protein with each meal to protect muscle; use soft, moist textures if chewing is hard. Swallowing therapy should guide textures/liquids. ASHA

3. Hydration plan (small, frequent sips; thickened liquids only if prescribed). ASHA Apps

4. Vitamin D and calcium sources for bone: dairy/fortified plant milks, small fish, greens; supplement if labs low. Office of Dietary Supplements

5. B-vitamin sufficiency (B1/B12) via varied diet; supplement only if deficient. Office of Dietary Supplements+1

6. Healthy fats (olive oil, nuts, omega-3s) over trans fats and excessive saturated fat. Office of Dietary Supplements

7. Limit alcohol (worsens balance, neuropathy, and falls). (General neurorehab precaution.) PMC

8. Avoid mega-dose supplements unless prescribed; vitamin E excess raises bleeding risk. Office of Dietary Supplements

9. Be careful with turmeric/curcumin pills (drug interactions); prefer culinary use. NCCIH

10. Use third-party-tested supplements and review every product with your clinician (label quality varies). (NIH ODS resource hub.) Office of Dietary Supplements

Frequently asked questions

1. Is SCAR10 curable?
   Not yet. Current care focuses on rehab and symptom control. Disease-modifying trials are being explored. PMC

2. Will therapy still help if the disease is progressive?
   Yes. Intensive, task-specific programs improve walking, balance, and daily function—even in degenerative ataxias—especially when started early and refreshed periodically. PMC

3. Can special shoes/braces fix ataxia?
   They do not fix timing errors but can increase stability and confidence for specific problems (e.g., ankle instability). A PT should assess which aid helps without reducing needed feedback. PMC

4. What about “cerebellar stimulation” devices?
   Non-invasive brain stimulation (tDCS/rTMS) is investigational. Join clinical trials rather than buying unproven devices. MDPI

5. Are there pills that directly treat ataxia?
   No drug is FDA-approved to reverse cerebellar ataxia. Medicines target symptoms like spasticity, tremor, pain, mood, or orthostatic dizziness. PMC

6. Is dalfampridine helpful?
   It’s approved to improve walking in MS; data in ataxias are limited and mixed. Consider only with clinician oversight, weighing seizure risk. FDA Access Data

7. When should we consider a feeding tube (PEG)?
   If swallowing is unsafe or intake is inadequate despite therapy, PEG supports nutrition, reduces aspiration risk, and makes meds easier—timed after careful swallow testing and counseling. PMC

8. Are stem-cell clinics legitimate for ataxia right now?
   No. Outside clinical trials, these are unapproved and may be unsafe or unlawful. Avoid them. U.S. Food and Drug Administration

9. Do supplements cure SCAR10?
   No. Use supplements to correct proven deficiencies (D, B12, etc.) or for general health support; they don’t modify the disease. Office of Dietary Supplements+1

10. Why treat mood in a movement disorder?
    Depression/anxiety lower energy and engagement in rehab, increasing disability. Treating mood improves function and quality of life. continuum.aan.com

11. Can speech therapy help if my speech is already slurred?
    Yes. Training breath/voice/pacing often improves intelligibility and reduces fatigue. Early referral is best. National Ataxia Foundation

12. How do we prevent pneumonia?
    Swallow assessment, individualized texture strategies, and airway protection training, plus vaccinations and oral hygiene, lower risk. ASHA Apps

13. What if I get dizzy on standing?
