Neuroocular Syndrome 2

Neuroocular syndrome 2, paroxysmal type (NOC2)”—a disorder best known for recurrent upward eye deviation (or vertical nystagmus) with abnormal head posturing from infancy, often with ataxia (unsteady movements).

Neuroocular syndrome 2 (paroxysmal type) is a rare childhood-onset neurologic condition in which babies or infants have daily “spells” where the eyes drift up or beat up-and-down, and the head tilts to compensate. These episodes often happen after sleep and can come with low muscle tone, clumsiness, mild speech trouble, and a wobbly gait. Seizures are typically not present. Over time, the eye events usually improve, but some children keep mild coordination issues. Doctors think NOC2 overlaps with the entity “benign paroxysmal tonic upgaze with ataxia”, and in some families it can follow an autosomal-dominant inheritance. Reported genes in similar phenotypes include CACNA1A/CACNA1G calcium-channel variants, which help explain the paroxysmal eye and balance features. Frontiers+4malacards.org+4NCBI+4

Neuro-ocular syndrome 2, paroxysmal type (NOC2) is a very rare childhood disorder. In simple words, babies or young children have short, repeated attacks (“paroxysms”) where the eyes suddenly hold an upward position or jerk in a rhythm (nystagmus). During an episode, the child may also tilt the head into an unusual posture to steady the vision. These spells usually start from birth or early infancy, often come right after sleep, and get better with age. Most children have low muscle tone (hypotonia), a wobbly walk (ataxia), mild speech difficulty (dysarthria), and mild developmental delay. Importantly, true seizures are usually not present. The condition is typically described as autosomal dominant, which means a single changed gene copy can be enough to cause the syndrome in a family, though some cases appear “new” (de novo). NCBI+2UniProt+2

Scientists group NOC2 among disorders where the brain’s eye-movement control and cerebellum do not work perfectly for brief periods. Similar eye postures can occur in other conditions, so careful evaluation is needed to rule out epilepsy and structural brain problems. ScienceDirect+1

Other names

• Benign paroxysmal tonic upgaze of childhood with ataxia (BPTU-A)

• Paroxysmal tonic upgaze (PTU) with ataxia

• Neuro-ocular syndrome 2, paroxysmal type (NOC2)
  These names all point to the same core picture: spells of sustained upward eye deviation in young children, often with unsteady movements. NCBI+1

Types

Because NOC2 is rare, doctors often sort cases by how the spells look, when they occur, and what causes are found. These “types” are clinical groupings to guide care—they are not official subtypes:

1. Sleep-triggered paroxysmal type
   Attacks mainly after naps or overnight sleep; classic for NOC2. NCBI

2. Cerebellar-predominant type
   Upward gaze spells plus stronger ataxia and low muscle tone in between episodes. NCBI

3. Eye-movement–predominant type
   Frequent tonic upgaze or vertical nystagmus with only mild gait imbalance. NCBI

4. Gene-associated patterns
   — CACNA1A-related: channelopathy affecting cerebellar circuits; may link to episodic ataxia or migraine in families.
   — GRID2-related: cerebellar atrophy and intermittent tonic upgaze/nystagmus.
   — SEPSECS-related or DAGLA-related: rarer pathways affecting eye movement networks. (These genes are connected to paroxysmal tonic upgaze or overlapping neuro-ocular syndromes in the literature.) OUP Academic+3ScienceDirect+3American Academy of Neurology+3

Causes

Important: In many children, no single cause is proven; genetics and brain-circuit immaturity are leading ideas. Below are plausible, documented causes or contributors from medical literature and related syndromes that show the same core sign (paroxysmal tonic upgaze/vertical nystagmus) or the same clinical family (paroxysmal neuro-ocular syndromes). Your clinician will tailor testing based on the child.

1. CACNA1A gene variants
   Changes in a calcium channel gene can disrupt signal timing in cerebellar and ocular motor pathways, producing episodic upgaze and ataxia. PMC+1

2. GRID2 gene deletions/mutations
   A glutamate receptor in cerebellum; defects can cause cerebellar atrophy and intermittent tonic upgaze/nystagmus. American Academy of Neurology

3. SEPSECS gene variants
   A tRNA-related gene; reported in children with PTU-like eye signs among broader neurodevelopmental features. ScienceDirect

4. DAGLA gene variants
   An endocannabinoid pathway gene; linked to a pediatric neuro-ocular syndrome with developmental delay and abnormal eye movements. OUP Academic

5. Autosomal dominant inheritance
   Family history can reveal multiple affected members, supporting a dominant pattern in NOC2. UniProt

6. De novo (new) mutations
   A child can be the first in a family with a new variant, explaining a negative family history. (Common in rare pediatric neurogenetic disorders.) PMC

7. Immature cerebellar circuits in infancy
   The cerebellum fine-tunes eye movements; immature networks may misfire episodically, then stabilize with age. (Inferred from natural improvement over time.) NCBI

8. Sleep-state transitions
   Episodes often appear after sleep, likely due to shifts in arousal chemicals and brainstem eye-movement control. NCBI

9. Intercurrent illness or fatigue
   Parents note more spells with fever or tiredness, common triggers in paroxysmal movement disorders. digitalcommons.library.tmc.edu

10. Channelopathies beyond CACNA1A
    Other ion-channel genes may rarely mimic NOC2 with paroxysmal eye postures. (Broader paroxysmal movement disorder literature.) MDPI

11. Cerebellar developmental anomalies
    Subtle maldevelopment can tilt the balance of ocular motor control toward upgaze bias. American Academy of Neurology

12. Neurotransmitter imbalance (glutamatergic/GABAergic)
    Abnormal cerebellar excitation/inhibition can drive nystagmus/tonic gaze spells. (Mechanistic link via GRID2 and cerebellar circuitry.) American Academy of Neurology

13. Endocannabinoid signaling disruption
    DAGLA findings suggest impaired modulation of synapses involved in eye control. OUP Academic

14. Benign developmental phenomenon
    Some infants show PTU that is self-limited without a detectable gene change. digitalcommons.library.tmc.edu

15. Medication sensitivity (rare)
    Drugs affecting cerebellar function (e.g., certain anticonvulsants) can unmask or worsen nystagmus in susceptible children (general neuro-ophthalmic principle). (Use clinician guidance.)

16. Metabolic stressors
    Low glucose or electrolytes occasionally worsen paroxysmal movements in vulnerable brains; screening is part of evaluation. (General pediatric neurology practice.)

17. Post-viral cerebellitis (differential)
    Can cause acute nystagmus/ataxia resembling NOC2 but not paroxysmal; considered to exclude rather than cause NOC2. (Included to show careful work-up.)

18. Structural brain/visual pathway lesions (differential)
    Lesions can mimic persistent upgaze/nystagmus—MRI helps rule these out. (Diagnostic principle.)

19. Epileptic events (differential)
    Occipital seizures can cause eye deviation; video-EEG helps separate epilepsy from NOC2. www.elsevier.com

20. Chromosome 15 disorders (mimics)
    Angelman/Prader-Willi region changes reported with PTU-like features in some cases; part of the differential. www.elsevier.com

Diagnostic tests

A. Physical examination (bedside assessment)

1. General pediatric and neurologic exam
   Checks tone, reflexes, balance, and eye movements at rest and during fixation/tracking. Patterns consistent with NOC2 (tonic upgaze, vertical nystagmus, hypotonia, mild ataxia) support the diagnosis. NCBI

2. Ocular motility exam
   Doctor watches how the eyes move up, down, and sideways; in NOC2, vertical holding or jerks are prominent while horizontal movements are often spared. malacards.org

3. Observation after sleep / fatigue provocation
   Because spells often follow sleep, planned observation after a nap increases the chance of seeing a typical episode safely. NCBI

4. Gait and posture assessment
   Simple tasks (heel-toe, standing still) reveal ataxia or compensatory head postures used during spells. NCBI

B. “Manual” clinic tests and structured bedside tools

5. Video recording of spells (home or clinic)
   Short videos help specialists confirm the pattern of eye deviation, rule out seizures, and track improvement over months. (Standard movement-disorder practice; emphasized in PTU literature.) digitalcommons.library.tmc.edu

6. Clinical rating of ataxia (e.g., SARA adapted for age)
   Structured scoring documents day-to-day function and response to simple measures (rest, triggers). (Common ataxia practice.)

7. Fixation-suppression checks
   Having the child fixate a target may briefly reduce nystagmus; response patterns aid localization to cerebellar networks. (Neuro-ophthalmology principle.)

C. Laboratory and pathological tests (to exclude mimics / find causes)

8. Genetic testing panel for paroxysmal movement/eye-movement disorders
   Looks for variants in CACNA1A, GRID2, SEPSECS, DAGLA and related genes. A positive result supports a neurogenetic cause. OUP Academic+3Children’s Hospital of Philadelphia+3American Academy of Neurology+3

9. Targeted single-gene testing (when history suggests)
   Example: strong family history of episodic ataxia/migraine suggests CACNA1A first. PMC

10. Metabolic screening
    Basic labs (glucose, electrolytes, thyroid, B12/folate when indicated) help rule out metabolic triggers that can worsen paroxysmal movements. (General pediatric neurology practice.)

11. Chromosomal microarray / exome sequencing
    Used when panel is negative but suspicion remains; identifies copy-number changes (e.g., in GRID2 region) or rare variants. American Academy of Neurology

D. Electrodiagnostic tests

12. Video-EEG monitoring
    Captures an event to exclude epileptic seizures; in NOC2/PTU, EEG is usually normal or shows no seizure pattern despite eye deviation. www.elsevier.com

13. Eye movement recording (video-oculography)
    Measures nystagmus and gaze holding precisely, confirming vertical predominance and helping with follow-up. (Standard neuro-ophthalmic tool.)

14. Vestibular testing (age-adapted)
    Occasionally used to assess balance systems; often normal in NOC2 but useful when ataxia seems out of proportion. (Clinical utility varies.)

E. Imaging tests

15. Brain MRI (with focus on cerebellum/brainstem)
    Usually normal in classic NOC2; done to rule out structural causes and to look for cerebellar atrophy when GRID2 or other disorders are suspected. American Academy of Neurology+1

16. High-resolution MRI of visual pathways (selected cases)
    Used when the exam suggests a visual pathway lesion to exclude other diagnoses. (Imaging principle.)

17. Diffusion and spectroscopy (selected research/complex cases)
    Can show microstructural or metabolic changes if the clinical picture is atypical. (Specialist use.)

F. Functional and developmental assessments

18. Speech-language evaluation
    Rates dysarthria and expressive language; guides therapy planning. NCBI

19. Developmental and cognitive testing
    Documents mild intellectual impairment when present, and informs educational support. NCBI

20. Physical and occupational therapy assessments
    Quantify hypotonia, coordination, and daily-living skills to personalize therapy.

Drug treatments

Important: No drug is FDA-approved specifically for NOC2/PTU. Clinicians sometimes use off-label medicines to manage ataxia, nystagmus, or suspected absence seizures. FDA citations below document each drug’s official labeling (indications, dosing, safety), not an approval for NOC2.

1) Acetazolamide (Diamox/Sequels) – carbonic anhydrase inhibitor used in episodic ataxias; several PTU/ataxia cases improved. Class: Carbonic anhydrase inhibitor.

Dietary molecular supplements

These do not treat NOC2, but support general neuro-ocular health. Always discuss dosing with the child’s clinician.

1. Omega-3 fatty acids (DHA/EPA). Support neural membranes and retinal function; common pediatric doses are tailored to age/weight from food or supplements; monitor for GI upset. Office of Dietary Supplements

2. Lutein/zeaxanthin. Macular pigments that filter blue light and support retinal processing; obtained from leafy greens/eggs; supplements vary by brand. PMC+1

3. Vitamin D. Supports neuro-muscular function and immunity; check blood levels and supplement to reach adequacy. Office of Dietary Supplements+1

4. Magnesium. Cofactor in >300 enzymes; low levels can increase neuromuscular excitability; forms like citrate are more bioavailable. Office of Dietary Supplements+1

5. Coenzyme Q10. Mitochondrial cofactor; sometimes used for fatigue; evidence mixed. NCCIH+1

6. B-complex (esp. B1, B2, B6, B12). Support energy pathways and nerve health; avoid megadoses without indication. Office of Dietary Supplements

7. Alpha-lipoic acid. Antioxidant supporting mitochondrial redox cycles (adult neuropathy data); pediatric use is specialist-guided. Office of Dietary Supplements

8. L-carnitine. Fatty-acid transport; sometimes used in mitochondrial disorders; coordinate with clinician. Office of Dietary Supplements

9. N-acetylcysteine (NAC). Glutathione precursor; antioxidant rationale only. Office of Dietary Supplements

10. Multinutrient diet first. Emphasize fish, greens, legumes, nuts, fruit; supplements fill gaps rather than replace food. Office of Dietary Supplements

Immunity booster / regenerative / stem-cell drugs

There are no FDA-approved “immunity-boosting,” regenerative, or stem-cell drugs for NOC2/PTU. Experimental cell therapies are not established for this condition in children, and unregulated stem-cell products can be dangerous. Focus instead on routine vaccines, good nutrition, therapy programs, and targeted treatment of co-occurring problems (e.g., confirmed seizures, persistent strabismus). If you are exploring clinical trials, do so only through legitimate registries with a pediatric neurologist’s guidance. (No FDA citation exists for stem-cell drugs in NOC2.)

Surgeries (when and why)

1. Strabismus botulinum injection (minor procedure) if constant eye misalignment develops and doesn’t respond to observation—improves alignment and reduces abnormal head posture. FDA Access Data+1

2. Strabismus muscle surgery for persistent, large-angle deviations affecting function after full ophthalmology work-up. FDA Access Data

3. Ptosis repair if significant eyelid droop obstructs vision (rare in NOC2). rarediseases.info.nih.gov

4. Tear-duct procedures only if coexisting obstruction causes infections (not NOC2-specific). rarediseases.info.nih.gov

5. Device-assisted therapy (pumps) refers to intrathecal baclofen for severe spasticity in other disorders; not typical for NOC2. FDA Access Data
