Autosomal recessive spinocerebellar ataxia 14 (SCAR14) is a rare, inherited brain disorder. It mainly affects the cerebellum, which controls balance, movement, and eye control. Children usually show delayed milestones first. They may sit, stand, or walk later than other children. As they grow, unsteady walking and poor coordination appear. Eye movement problems are common. Brain scans often show shrinkage (atrophy) of the cerebellum. Thinking and learning problems can occur. SCAR14 is caused by harmful changes (variants) in a gene called SPTBN2, and a child must inherit one non-working copy from each parent. malacards.org+2alliancegenome.org+2

Autosomal recessive spinocerebellar ataxia 14 (SCAR14) is a rare, inherited brain disorder that mainly affects the cerebellum, the part of the brain that controls balance, eye movements, speech, and coordination. Children usually have global developmental delay and later develop gait ataxia (unsteady walking), hand clumsiness, abnormal eye movements, and sometimes intellectual disability. Brain scans often show cerebellar atrophy (shrinkage). “Autosomal recessive” means a child must inherit a faulty gene from both parents to be affected. SCAR14 is most often caused by pathogenic variants in SPTBN2, the gene that codes for β-III spectrin, a structural protein that keeps nerve cell membranes and synapses stable in the cerebellum. malacards.org+2PLOS+2

How it differs from “SCA14.” Medical names can be confusing: SCA14 (without “autosomal recessive”) usually refers to a dominant ataxia linked to the PRKCG gene, which is a different disease and inheritance pattern. In contrast, SCAR14 is recessive and most often involves SPTBN2. Using the correct name prevents mix-ups in genetic testing and counseling. Wikipedia

Scientifically, SPTBN2 encodes β-III spectrin, a scaffold protein that helps Purkinje cells in the cerebellum keep their shape and move cargo inside the cell. When β-III spectrin does not work, Purkinje cells malfunction and slowly degenerate. This leads to ataxia and eye movement problems. Homozygous or compound-heterozygous SPTBN2 variants are the usual cause of SCAR14. genecards.org+1

Other names

This condition is also called:

1. SCAR14 (Spinocerebellar ataxia, autosomal recessive 14)
2. Spectrin-associated autosomal recessive cerebellar ataxia
3. SPTBN2-related autosomal recessive cerebellar ataxia
4. Autosomal recessive spinocerebellar ataxia type 14

All of these names refer to the same disorder linked to recessive SPTBN2 variants. orpha.net+1

Types

There are no official subtypes inside SCAR14, but doctors often group patients by age at onset and key features. These “types” are practical categories to help with care and counseling:

1. Infantile-onset SCAR14 – global developmental delay in infancy, early hypotonia, very early gait ataxia, and eye movement problems; cerebellar atrophy is common on MRI. malacards.org

2. Childhood-onset SCAR14 – delayed motor milestones, unsteady gait in early childhood, limb incoordination, speech delay or dysarthria, and cerebellar atrophy on MRI. malacards.org

3. SCAR14 with prominent eye movement signs – noticeable nystagmus, hypometric saccades, jerky pursuit, and convergent squint alongside gait ataxia. malacards.org

4. SCAR14 with intellectual disability – various levels of learning difficulty combined with ataxia and cerebellar atrophy. malacards.org

(These categories reflect patterns reported across summaries of recessive SPTBN2 disease; they are not official genetic subtypes.) malacards.org

Causes

Remember: SCAR14 is monogenic—the root cause is harmful variants in SPTBN2. Below are 20 practical “causes” describing the specific ways variants and downstream biology lead to disease expression:

1. Biallelic SPTBN2 loss-of-function variants (both copies altered) cause Purkinje cell dysfunction and ataxia. zfin.org

2. Nonsense (stop) variants truncate β-III spectrin, producing unstable or non-functional protein. genecards.org

3. Frameshift variants change the reading frame and disrupt key spectrin domains. genecards.org

4. Splice-site variants mis-splice the RNA, removing or altering essential segments. genecards.org

5. Missense variants in critical repeats alter spectrin folding and stability. genecards.org

6. Compound heterozygosity (two different harmful variants, one on each copy) results in β-III spectrin failure. zfin.org

7. Defective spectrin–actin network weakens the neuronal scaffold in Purkinje cells. genecards.org

8. Impaired dendritic architecture disrupts Purkinje cell dendrite growth and branching. (Shown broadly for spectrin/PKCγ-Purkinje biology.) PMC

9. Abnormal membrane protein trafficking reduces delivery of ion channels and receptors to synapses. genecards.org

10. Disrupted glutamate receptor handling affects Purkinje cell input and cerebellar signaling. genecards.org

11. Disturbed calcium homeostasis in Purkinje cells adds to firing instability. genecards.org

12. Axonal transport problems impede movement of cargo along Purkinje axons. genecards.org

13. Synaptic dysfunction weakens communication within cerebellar circuits. genecards.org

14. Progressive Purkinje cell degeneration leads to cerebellar atrophy on MRI. malacards.org

15. Developmental vulnerability of the cerebellum explains infantile or childhood onset. malacards.org

16. Homozygous hot-spot variants in SPTBN2 reported in families with severe early disease. malacards.org

17. Gene–environment neutrality (no proven environmental trigger), emphasizing genetic causation. malacards.org

18. No dominant-negative effect in SCAR14 (recessive), unlike PRKCG-related dominant SCA14—different gene and mechanism. NCBI+1

19. Distinct from SPTBN2-dominant SCA5—same gene can cause another ataxia when variants are heterozygous/dominant. genecards.org

20. Genetic founder effects in some populations may cluster specific SPTBN2 variants. (Inferred from case-series patterns in rare disease databases.) malacards.org

Symptoms

1. Unsteady gait – walking is wide-based and wobbly; the child may fall often. malacards.org

2. Poor limb coordination – hands overshoot or undershoot targets (dysmetria). malacards.org

3. Slow rapid-alternating movements – trouble with fast hand or foot taps (dysdiadochokinesia). malacards.org

4. Eye movement problems – nystagmus, jerky pursuit, or small saccades. malacards.org

5. Speech problems – slurred or scanning speech (dysarthria). malacards.org

6. Developmental delay – late sitting, standing, or walking. malacards.org

7. Hypotonia – low muscle tone in infancy. malacards.org

8. Truncal ataxia – trouble sitting or standing still without swaying. malacards.org

9. Tremor – shaking of hands during action. malacards.org

10. Learning difficulties – mild to severe intellectual disability may be present. malacards.org

11. Fatigue with walking – extra effort due to poor balance. malacards.org

12. Frequent falls – common in childhood during play. malacards.org

13. Difficulty with fine motor tasks – buttons, small toys, or handwriting are hard. malacards.org

14. Feeding or swallowing issues – sometimes present because of coordination problems. malacards.org

15. Emotional frustration – children may feel upset by slow progress and repeated falls; this is common in chronic ataxias. malacards.org

Diagnostic tests

A) Physical examination (at the bedside)

1. Gait observation – the doctor watches how the child walks and turns; a wide-based, sway-prone gait suggests cerebellar ataxia. malacards.org

2. Romberg test – standing with feet together and eyes closed; increased sway suggests balance system problems. (Standard ataxia assessment.) malacards.org

3. Finger-to-nose – the child tries to touch their nose smoothly; overshoot shows dysmetria. malacards.org

4. Heel-to-shin – sliding the heel down the opposite shin tests leg coordination; wobble indicates ataxia. malacards.org

5. Rapid alternating movements – quick hand flips test cerebellar timing; slowness or irregular rhythm supports ataxia. malacards.org

B) Manual/bedside oculomotor tests

6. Saccade testing – the doctor asks the child to look quickly between two targets; small or slow jumps suggest cerebellar control issues. malacards.org

7. Smooth pursuit – following a moving finger; jerky pursuit is typical in cerebellar disease. malacards.org

8. Nystagmus check – brief eye beats at rest or gaze; common in cerebellar syndromes like SCAR14. malacards.org

C) Laboratory and pathological tests

9. Targeted gene panel for ataxia – looks for SPTBN2 variants along with many other ataxia genes; useful first genetic test in many clinics. invitae.com

10. Whole-exome sequencing (WES) – examines coding genes; helps when panel is negative or when family history is unclear. invitae.com

11. Parental testing – confirms autosomal recessive inheritance by showing one variant in each parent. zfin.org

12. Basic metabolic screen – glucose, electrolytes, thyroid, vitamin E/B12, lactate, ammonia; this helps rule out other treatable ataxias. (Standard practice in ataxia workups.) malacards.org

13. Creatine kinase (CK) – usually normal, but can exclude myopathy as a main cause of motor delay. (General neuromuscular screening.) malacards.org

D) Electrodiagnostic tests

14. EEG – used when spells suggest seizures or staring episodes; seizures are not core to SCAR14, but some recessive ataxias have them. orpha.net

15. EMG and nerve conduction studies – help rule out peripheral neuropathy if numbness or weakness is suspected; SCAR14 is primarily cerebellar. malacards.org

16. Evoked potentials (visual or somatosensory) – can show slowed brain pathway signals; sometimes used in complex ataxia evaluations. malacards.org

E) Imaging tests

17. Brain MRI – key test; often shows cerebellar atrophy (shrinkage), which supports the diagnosis together with symptoms and genetics. malacards.org

18. Tensor imaging or volumetry (advanced MRI) – research-level tools that quantify cerebellar pathway changes; used in specialized centers. malacards.org

19. Spine MRI – not routine, but may be done to rule out other causes of gait problems if signs point to the spinal cord. (General ataxia workup logic.) malacards.org

20. Oculography (video eye tracking) – documents nystagmus and saccade metrics; helpful for objective follow-up. (Used in ataxia clinics and studies.) malacards.org

Dietary molecular supplements

1. Coenzyme Q10 (CoQ10/ubiquinone or ubiquinol). Some hereditary ataxias due to primary CoQ10 deficiency improve with supplementation; benefit in non-deficiency ataxias is variable but plausible via mitochondrial support. Doses in reports range from ~15–30 mg/kg/day in children or up to 1200–2400 mg/day in adults; monitor for GI upset. PMC+2PMC+2

2. Vitamin E (alpha-tocopherol). Only disease-modifying when the ataxia is due to vitamin E deficiency (AVED); very high lifelong doses can stabilize or improve symptoms. In non-deficient SCAR14, routine high-dose vitamin E is not proven. Check a level first. NCBI+1

3. Omega-3 fatty acids. May support cardiovascular and general neural health; neurologic ataxia benefit is uncertain; consider for overall wellness if diet is low in fish. pn.bmj.com

4. Creatine monohydrate. Supports short-burst muscle energy; limited ataxia evidence; monitor for weight gain and cramps; ensure kidney health. pn.bmj.com

5. N-acetylcysteine (NAC). Antioxidant/glutathione precursor being explored for neuroprotection; evidence in ataxias is preliminary. Frontiers

6. Alpha-lipoic acid. Antioxidant with mixed neurologic data; may help neuropathic symptoms in diabetes; monitor for GI and hypoglycemia. pn.bmj.com

7. Vitamin D (optimize to normal). Supports bone health and fall-related fracture prevention; supplement only if low. pn.bmj.com

8. B-complex (B1, B6, B12) when deficient. Correcting documented deficiencies can improve neuropathy and fatigue. Avoid excess B6, which can itself cause neuropathy. pn.bmj.com

9. Magnesium (for cramps if low). Check levels first; GI side effects possible. pn.bmj.com

10. Zinc/selenium (only if deficient). Replace documented deficits to support immune and antioxidant enzymes; avoid high chronic doses. pn.bmj.com

Immunity-booster / regenerative / stem-cell” drugs

There are no approved immune-booster, regenerative, or stem-cell drugs for SCAR14. Below are areas sometimes discussed; all are investigational or supportive and should only be considered in trials or specialist care.

1. CoQ10 in proven primary CoQ10-deficiency ataxias (disease-specific, not SCAR14). Mechanism: mitochondrial electron transport support; dosing above. Evidence is mixed and genotype-dependent. PMC+1

2. Antioxidant strategies (e.g., NAC, alpha-lipoic acid). Mechanism: reduce oxidative stress; human ataxia data are limited. Frontiers

3. Neurotrophic modulation (riluzole). Mechanism: glutamate modulation; approved for ALS; mixed ataxia data; monitor liver tests. FDA Access Data

4. Cell-based therapies (experimental DBS-paired neurorehab concepts). Mechanism: neuromodulation rather than regeneration; early reports show tremor benefit in selected ataxias, not disease reversal. American Academy of Neurology

5. Gene-targeted approaches. Mechanism: correcting or bypassing SPTBN2 defects is a research goal; not clinically available yet. MDPI

6. Exercise-induced neuroplasticity (high-intensity, task-specific rehab). Mechanism: strengthens compensatory networks; current best “regenerative-like” option with real-world gains. PMC

3. Deep brain stimulation (DBS) targeting thalamic VIM or cerebellar circuits for disabling tremor/dystonia in select cases. Purpose: symptom relief when medications fail. Evidence: case series and reviews show tremor improvement; ataxia itself generally does not improve. American Academy of Neurology+1

4. Orthopedic procedures (e.g., tendon releases, foot deformity correction) if contractures or deformities cause pain or prevent bracing. Purpose: improve comfort, fit of orthoses, and mobility. Mechanism: mechanical alignment. pn.bmj.com

5. Strabismus/oculomotor procedures in rare cases of fixed misalignment causing diplopia after failure of prism/therapy. Purpose: reduce double vision. pn.bmj.com

---

When to see a doctor (red flags)

See a neurologist urgently for new choking, repeated aspiration, rapid worsening, new seizures, severe depression or suicidal thoughts, sudden vision loss/double vision, or major falls with injury. Regular follow-up is needed to adjust therapy, review safety of medicines, and update genetic counseling as new data emerge. BioMed Central+1

What to eat & what to avoid

1. Eat: protein-adequate, calorie-sufficient meals; small frequent portions if fatigue. BioMed Central

2. Eat: soft, moist textures if swallowing is difficult (dietitian-guided). BioMed Central

3. Eat: fiber-rich foods and fluids to prevent constipation from low mobility. pn.bmj.com

4. Eat: sources of vitamin D and calcium if low (or supplement as advised). pn.bmj.com

5. Consider: CoQ10 only after discussing realistic goals; evidence is mixed outside deficiency states. PMC

6. Avoid: alcohol and sedative drugs that worsen balance. pn.bmj.com

7. Avoid: crash diets—weight loss can reduce strength and increase falls. BioMed Central

8. Avoid: very thin liquids if advised by a swallow therapist (use thickened fluids). BioMed Central

9. Avoid: high-dose supplements without a deficiency or plan—possible side effects and interactions. pn.bmj.com

10. Hydrate: dehydration increases dizziness and fall risk. pn.bmj.com
