Autosomal Recessive Cerebellar Ataxia–Epilepsy–Intellectual Disability Syndrome due to WWOX Deficiency

Autosomal Recessive Cerebellar Ataxia–Epilepsy–Intellectual Disability Syndrome due to WWOX Deficiency is a rare, inherited brain disorder. A baby is born with two faulty copies of a gene called WWOX. Because the WWOX protein does not work well or is missing, the brain does not develop and function normally. Children develop early problems with balance and movement (cerebellar ataxia), hard-to-control seizures (epilepsy), and learning and thinking problems (intellectual disability). Symptoms often begin in infancy, seizures can be resistant to medicines, and development is very delayed. Brain scans may show small or under-developed parts of the brain, especially the cerebellum and white matter. The disorder is autosomal recessive, which means both parents usually carry one silent faulty copy and have a one-in-four chance in each pregnancy of having an affected child. Frontiers+3rarediseases.info.nih.gov+3NCBI+3

WWOX-deficiency neurological syndrome is a rare genetic condition caused by harmful changes (mutations) in both copies of the WWOX gene. The gene helps brain cells develop, connect, and function. When it does not work, babies usually develop early, hard-to-control seizures, low muscle tone, movement and balance problems (ataxia), and severe developmental delay with intellectual disability. Many children also have feeding difficulties, poor growth, and may need devices to help with breathing or nutrition. There is no cure yet; care focuses on seizure control, nutrition, therapies, assistive technology, and family support. Research indicates WWOX loss impairs normal central nervous system development and is a recognized (though rare) autosomal-recessive cause of developmental and epileptic encephalopathy.

Other names

• WOREE syndrome (WWOX-related epileptic encephalopathy)

• Developmental and epileptic encephalopathy 28 (DEE28, also called EIEE28)

• Autosomal recessive spinocerebellar ataxia-epilepsy-intellectual disability due to WWOX (historically linked with SCAR12 in milder forms)
  These names all point to the same gene, WWOX, and a spectrum from very severe early epileptic encephalopathy (WOREE/DEE28) to a milder ataxia-epilepsy-ID picture. einsteinmed.edu+3National Organization for Rare Disorders+3Wiley Online Library+3

Types

1. Severe, early-infantile form (WOREE / WWOX-DEE / DEE28). Seizures start in the first months of life, are often drug-resistant, development is profoundly impaired, tone is very low, and vision problems (optic or retinal) may appear. Early death can occur. This form is usually caused by null or loss-of-function variants on both WWOX copies. NCBI+2PubMed+2

2. Milder childhood form (autosomal recessive spinocerebellar ataxia with epilepsy and ID). Children walk later, have ataxia, learning difficulties, and seizures that may be easier to control; MRI may show mild cerebellar atrophy. This form is often linked to hypomorphic or partial loss-of-function variants. rarediseases.info.nih.gov+1

(Researchers view these as points on a single WWOX spectrum, where the variant’s severity (complete loss vs partial function) tracks with how severe the child’s symptoms are.) Nature

Causes

Although there is one root cause—faulty WWOX—there are many genetic change types that can damage this gene or protein. Each of the items below is a known or plausible mechanism reported in the WWOX literature:

1. Homozygous nonsense variant. A “stop” change cuts the protein short, usually destroying function; seen in severe WOREE cases. Nature

2. Homozygous frameshift variant. Small insertions/deletions shift the reading frame and make a broken protein; typically severe. Nature

3. Homozygous splice-site variant. Disrupts how exons are joined, often skipping key exons and ruining the protein. Frontiers

4. Homozygous missense variant (critical residue). A single amino-acid change can inactivate WWOX if it hits an essential spot. Severity depends on location. Nature

5. Compound heterozygous variants. One damaging change on each parental copy (two different variants) combine to cause disease. Frontiers

6. Exon-level deletion (copy-number loss). One or more exons are missing; for example, deletion of exons 1–6 produced a null genotype and severe disease. Nature

7. Whole-gene deletion. The entire WWOX gene is lost on one or both copies; biallelic loss is usually lethal or very severe. Nature

8. Duplications disrupting gene structure. Extra copied pieces can scramble the gene’s layout and block normal function. Frontiers

9. Regulatory/ promoter variants (reduced expression). Variants outside exons can lower how much WWOX is made, leading to partial deficiency. (Inference from spectrum papers.) Nature

10. Partial loss-of-function missense (hypomorphic), e.g., P47T. The protein is made but works poorly, often causing milder ataxia-epilepsy-ID. ScienceDirect

11. Null genotypes on both alleles. Any combination that yields no functional protein causes the most severe WOREE picture. Nature

12. Founder variants in consanguineous families. Shared ancestry raises the chance both parents carry the same rare pathogenic variant. Nature

13. Complex rearrangements. Structural changes (inversions/insertions) can interrupt WWOX; severity depends on disruption. Nature

14. Deep intronic splice-altering changes. Hidden intronic variants may create abnormal splicing and truncated protein. Frontiers

15. Multi-exon copy-number gains that disturb splicing. Added exons can also break correct mRNA assembly. Frontiers

16. Uniparental isodisomy causing homozygosity for a pathogenic variant. Rarely, inheriting two identical copies from one parent can unmask a recessive variant (general mechanism in recessive disease; applied here as plausible). Nature

17. Compound effect with nearby fragile region (FRA16D). WWOX lies in a chromosomal fragile site; breaks here can involve WWOX and impair function. The WWOX Foundation

18. Pathogenic variants affecting WW domains. Damage within protein-interaction “WW” domains can block key neuronal pathways. Nature

19. Pathogenic variants affecting the SDR (oxidoreductase) domain. Loss of catalytic domain function disrupts brain development signaling. Nature

20. Biallelic variants identified by exome/genome sequencing. Modern sequencing often finds two disease-causing variants explaining the phenotype. Wiley Online Library

Immunity booster / regenerative / stem cell” drugs

There are no approved immune-booster, regenerative, or stem-cell drugs for WWOX-DEE. Unapproved stem-cell products marketed directly to families can be dangerous (infections, blindness, other severe harms). The FDA strongly warns patients to avoid clinics selling unapproved “regenerative” therapies outside regulated trials. If you see such offers, ask your neurologist and check FDA resources. U.S. Food and Drug Administration+2U.S. Food and Drug Administration+2

• IVIG (intravenous immunoglobulin): Sometimes used in specific immune-mediated epilepsies, not standard for WWOX-DEE. Mechanism: immune modulation. Use only under specialist guidance. NICE

• Experimental AAV gene therapy (research only): Animal studies show promise restoring WWOX, but human therapy remains in development; consider clinical trials only at qualified centers. EMBO Press+1

• Unapproved stem-cell infusions: Avoid outside trials—known risks, no proven benefit for epilepsy/WWOX-DEE. U.S. Food and Drug Administration

• “Immune boosters” sold online: No evidence they help WWOX-DEE; some interact with antiseizure drugs. Consult your doctor first. Office of Dietary Supplements

• Exosome products: Often illegally marketed; FDA has issued warnings. Avoid. U.S. Food and Drug Administration

• Any “regenerative injections” for neurologic cures: High risk of harm and cost; not recommended. Pew Charitable Trusts

Surgeries (what they are; why done)

1. Vagus nerve stimulation (implant)
   Procedure. Small generator under the skin connects to the left vagus nerve. Day-surgery in many centers; device is programmed during follow-up. Why. Considered when medicines fail and resective surgery is not an option; may reduce seizure frequency/severity and clusters. NICE

2. Corpus callosotomy
   Procedure. Disconnects fibers between hemispheres (sometimes with minimally invasive laser techniques). Why. Palliative option to reduce dangerous drop attacks and generalized seizures causing injuries. The Journal of Neurosurgery+1

3. Gastrostomy tube (G-tube)
   Procedure. Feeding tube placed through the abdomen. Why. For severe dysphagia, aspiration risk, poor weight gain, or to deliver KD formulas reliably. NICE

4. Orthopedic procedures
   Procedure. Tendon releases, hip surgery, or scoliosis surgery as needed. Why. Improve positioning, reduce pain, and ease care when tone or posture problems cause deformities. NICE

5. Tracheostomy (selected cases)
   Procedure. Surgical airway. Why. Rarely, for severe airway protection issues or recurrent aspiration with respiratory failure; considered only after multidisciplinary review. NICE

FAQs

1. Is there a cure for WWOX-DEE?
   Not yet. Care is supportive: seizure control, therapies, nutrition, and safety. Early research is exploring gene therapy but it is not approved. EMBO Press

2. Will seizures improve with age?
   Seizures are often hard to control; some children may stabilize with combined therapies (medicines, KD, VNS, rescue plan). Individual paths vary. NICE+1

3. Can diet really help?
   Yes. Ketogenic or related diets, when supervised, can reduce seizures in many children with drug-resistant epilepsy. Cochrane

4. Is VNS safe?
   VNS is an established option for drug-resistant epilepsy when resection is not suitable; discuss benefits/risks with your team. NICE

5. Should we try “stem cell therapy”?
   No—outside regulated trials these are unapproved and risky. Stick with proven treatments and discuss clinical trials with your neurologist. U.S. Food and Drug Administration

6. How can we reduce SUDEP risk?
   Aim for best seizure control, take medicines on time, consider night-time supervision/alerts in selected cases, and ensure seizure first-aid training. Epilepsy Foundation+1

7. Which medicine is “best”?
   There is no single “best” drug for WWOX-DEE. Doctors choose based on seizure types, side-effects, age, and interactions, guided by epilepsy guidelines and FDA labels. NICE

8. Are supplements necessary?
   Only if your team recommends them (for example, vitamin D or carnitine in specific situations). More is not better; interactions are possible. Office of Dietary Supplements

9. What if a seizure lasts over 5 minutes?
   Use the prescribed rescue medicine and follow your action plan; call emergency services if not stopping or if breathing concerns occur. CDC

10. Can my child learn to communicate?
    Yes—AAC (communication boards or devices) helps many children express choices and needs, improving quality of life. PMC

11. Will my other children be affected?
    Each pregnancy has a 25% chance if both parents are carriers. Genetic counseling explains options like prenatal or preimplantation testing. The WWOX Foundation

12. Are there warning signs of medicine side effects?
    Yes—liver issues (with valproate or CBD), mood changes (with levetiracetam/perampanel), rash (with lamotrigine), stones (with topiramate/zonisamide). Report new symptoms promptly.

13. Is emergency nasal midazolam safe at home?
    It’s FDA-approved for seizure clusters in people ≥12 years; clinicians may guide alternatives in younger children. Follow label frequency limits. FDA Access Data

14. Who should be on our care team?
    Pediatric neurologist/epileptologist, dietitian (for KD), PT/OT/SLP, feeding therapist, ophthalmologist, social worker, and palliative care as needed. NICE

15. Where can I read trusted guidance?
    NICE epilepsy guideline (NG217), CDC seizure first-aid pages, and Epilepsy Foundation resources are reliable starting points. NICE+1
