Arthrogryposis–Oculomotor Limitation–Electroretinal Anomalies Syndrome (AOLEAS)

Arthrogryposis–oculomotor limitation–electroretinal anomalies syndrome (AOLEAS) is a very rare, inherited condition. Children are born with joint contractures (stiff, bent joints at birth), especially in the hands and feet (arthrogryposis). They also have limited eye movements (oculomotor limitation / ophthalmoplegia) and abnormal electrical responses from the retina on electroretinogram (ERG) testing (electroretinal anomalies). In short, it affects joints and eyes from birth. Most care focuses on rehabilitation, supportive surgery for joints and eyelids/eye position, and low-vision support, because no single “curative” drug exists yet. Orpha+2BMJ Journals+2

Arthrogryposis–oculomotor limitation–electroretinal anomalies syndrome (AOLEAS) is a very rare, inherited condition. Children are born with joint contractures (stiff, bent joints at birth), especially in the hands and feet (arthrogryposis). They also have limited eye movements (oculomotor limitation / ophthalmoplegia) and abnormal electrical responses from the retina on electroretinogram (ERG) testing (electroretinal anomalies). In short, it affects joints and eyes from birth. Most care focuses on rehabilitation, supportive surgery for joints and eyelids/eye position, and low-vision support, because no single “curative” drug exists yet. Orpha+2BMJ Journals+2

This syndrome is a rare, inherited developmental condition. Babies are born with multiple tight or fixed joints (called “arthrogryposis”), limited eye movements (oculomotor limitation such as ptosis, strabismus or external ophthalmoplegia), and abnormal findings on retinal electrical testing (electroretinal anomalies on ERG). There is no primary disease of the nerves or muscles causing the limb contractures; instead, it is a developmental pattern that affects joints and some eye structures before birth. Intelligence is usually normal. Genetic Rare Disease Center

Other names

You may see this condition listed under several related labels in rare-disease catalogs. Common “also-called” terms include:

• Distal arthrogryposis type 5 (DA5)

• Distal arthrogryposis type IIB (DA IIB)

• Distal arthrogryposis with ophthalmoplegia

• Oculomelic amyoplasia

These terms reflect the pattern of hand/foot contractures plus eye-movement restriction; some case descriptions include abnormal ERG. The different labels have been used over time as doctors recognized overlapping features within the distal arthrogryposis group. Genetic Rare Disease Center+1

Types

Because this is very rare, experts mostly organize it by clinical pattern and inheritance rather than a large, rigid subtype list:

1. Distal arthrogryposis pattern with ophthalmoplegia and abnormal ERG. Classic description: hand/foot contractures, diminished palmar creases, deep-set eyes, restricted eye movements; an abnormal electroretinogram may be present in some individuals. ResearchGate

2. Inheritance-based types. Both autosomal dominant and autosomal recessive inheritance have been reported in this arthrogryposis–oculomotor phenotype family. De novo variants can also occur. Genetic Rare Disease Center

3. Genotype-associated presentations. Some distal arthrogryposis conditions (including DA5) are linked to variants in PIEZO2, a mechanosensory ion-channel gene; databases list PIEZO2 among genes associated with this phenotype family, but published gene-specific data for the exact “electroretinal anomalies” combination are limited. Genetic confirmation therefore uses broad panels or exome sequencing. Ma’ayan Lab

Practical take-home: in the clinic, doctors recognize a distal arthrogryposis with eye-movement involvement, sometimes with ERG abnormalities; the exact label may vary, and they will use inheritance pattern and genetic testing to refine the diagnosis. Genetic Rare Disease Center+1

Causes

All “causes” below are easy-English ways to describe what leads to this syndrome or the features doctors see. Most ultimately trace back to changes in developmental genes.

1. Genetic mutations that change how joints and eye tissues form before birth. Genetic Rare Disease Center

2. Autosomal dominant inheritance (one altered copy from a parent is enough). Genetic Rare Disease Center

3. Autosomal recessive inheritance (two altered copies, one from each parent). Genetic Rare Disease Center

4. De novo variants (a new change in the child not present in the parents). Genetic Rare Disease Center

5. Genes involved in distal arthrogryposis, such as PIEZO2, which affect how tendons, joints, and movement sensors develop in limbs and eye muscles. (Association reported in curated datasets for this phenotype family.) Ma’ayan Lab

6. Reduced fetal movement (a common mechanism in arthrogryposis in general), leading to tight joints by birth. PM&R KnowledgeNow

7. Developmental differences in extraocular muscles (the small muscles that move the eyes), causing ophthalmoplegia or strabismus. Nature

8. Abnormal development of cranial nerve pathways controlling eye movement (III, IV, VI), suggested in ophthalmoplegia reports within arthrogryposis groups. Nature

9. Retinal developmental changes that show up as an abnormal ERG (electrical test of retina). ResearchGate

10. Connective-tissue formation differences that contribute to reduced palmar creases and contractures. ResearchGate

11. Tendon and joint capsule stiffening in utero (a hallmark mechanism in arthrogryposis). PM&R KnowledgeNow

12. Facial skeletal development variants (e.g., deep-set eyes, triangular facies) often cataloged with this phenotype. Genetic Rare Disease Center

13. Variable penetrance—not all people with a variant show the same signs, which can “cause” a milder or atypical presentation in a family. Genetic Rare Disease Center

14. Genetic mosaicism in a parent (variant present in some cells), explaining sporadic recurrence in families. (General rare-disease genetics concept; used to interpret inheritance.) Genetic Rare Disease Center

15. Overlapping rare-syndrome spectra—some cases sit on a spectrum with other arthrogryposis-ocular phenotypes described in the literature. ResearchGate

16. Modifier genes that change severity of joint or ocular features in the same primary syndrome. Genetic Rare Disease Center

17. Epigenetic effects (how genes are turned on/off during development) that influence muscle/eye formation. Genetic Rare Disease Center

18. Environmental contributors are not primary causes, but general rare-disease guidance notes that environment sometimes interacts with genes; for this specific syndrome, genetic causes predominate. Genetic Rare Disease Center

19. Consanguinity (parents related) can raise the chance of recessive conditions expressing; this is a general genetic principle relevant in rare recessive arthrogryposis patterns. Genetic Rare Disease Center

20. Unknown genetic changes—because this is very rare, some families may have a yet-unidentified gene; clinicians therefore use broad sequencing to search. Genetic Rare Disease Center

Symptoms and signs

Below are common features documented for this phenotype family; not everyone has all features, and severity varies.

1. Joint contractures in hands/feet (distal arthrogryposis). Fingers may be bent (camptodactyly) and feet may be clubbed (talipes). This stiffness is present at birth. Genetic Rare Disease Center

2. Absent or reduced palmar creases. The palm lines can be faint or missing because the hand has been fixed in one position during fetal life. ResearchGate

3. Ophthalmoplegia (limited eye movement). Children may not be able to look fully in certain directions, or the eye movement can be slow or absent. Genetic Rare Disease Center

4. Ptosis (droopy eyelids). The upper eyelids can hang low and partly cover the pupil. Genetic Rare Disease Center

5. Strabismus (eye misalignment). Eyes may turn inward or outward because of weak or stiff extraocular muscles. Genetic Rare Disease Center

6. Abnormal electroretinogram (ERG). Electrical testing of the retina may show reduced responses, suggesting retinal involvement. ResearchGate

7. Visual impairment. Some individuals have reduced vision, sometimes linked to optic atrophy or retinal dysfunction. Genetic Rare Disease Center

8. Optic atrophy. The optic nerve can look pale on exam, indicating previous damage or under-development. Genetic Rare Disease Center

9. Deep-set eyes. The eyes can appear sunken due to facial bone and soft-tissue differences. Genetic Rare Disease Center

10. Triangular facial shape. Broad temples with a narrower chin can be seen. Genetic Rare Disease Center

11. Macrotia (large ears). Ears can be larger than average. Genetic Rare Disease Center

12. Joint stiffness beyond hands/feet. Elbows, knees, or shoulders can also be tight, affecting range of motion. Genetic Rare Disease Center

13. Arachnodactyly (long slender fingers) and deviation of fingers may be present. Genetic Rare Disease Center

14. Pectus excavatum (sunken chest) or other skeletal differences may be noted. Genetic Rare Disease Center

15. Normal cognition. In reported series, intelligence is typically normal, which helps distinguish this entity from some neurodevelopmental syndromes. Genetic Rare Disease Center

Additional eye issues have been reported across the broader arthrogryposis literature (e.g., progressive ophthalmoplegia, rare glaucoma, optic nerve findings), so careful ophthalmic follow-up is standard. Nature+2Lippincott Journals+2

Diagnostic tests

A. Physical examination 

1. Global musculoskeletal exam. A doctor checks all joints, documents which are stiff, measures angles, and looks for muscle bulk differences and skin creases. This establishes the “arthrogryposis” pattern. PM&R KnowledgeNow

2. Hand exam for palmar creases and camptodactyly. Absent creases and finger contractures support the distal arthrogryposis pattern. ResearchGate

3. Foot exam for clubfoot (talipes). Identifies position, flexibility, and need for early casting. Genetic Rare Disease Center

4. Craniofacial inspection. Looks for deep-set eyes, triangular face, ear size, and chest shape (pectus) to map the phenotype. Genetic Rare Disease Center

5. Basic neurologic screening. Ensures tone, reflexes, and strength are consistent with a non-primary neuromuscular cause (as expected in this syndrome). Genetic Rare Disease Center

B. Manual/bedside eye movement and vision tests 

6. Ocular motility exam (versions/ductions). The clinician guides the child to look in all directions to document ophthalmoplegia and any compensatory head turns. Genetic Rare Disease Center

7. Cover–uncover and alternate cover tests. Simple strabismus tests assess alignment to plan treatment (glasses, patching, or surgery). Genetic Rare Disease Center

8. Ptosis margin measurements. Eyelid position is measured (MRD1) to determine severity and surgical thresholds. Genetic Rare Disease Center

9. Visual acuity and fixation behavior for age. Uses age-appropriate charts or preferential looking to track vision over time. Genetic Rare Disease Center

10. Pupil and optic-disc check with ophthalmoscopy. Screens for optic atrophy and general retinal health at the bedside. Genetic Rare Disease Center

C. Laboratory and pathological/genetic tests 

11. Targeted rare-disease/arthrogryposis genetic panel or whole-exome sequencing. Looks for known genes in distal arthrogryposis (including PIEZO2) or discovers a novel variant when panels are negative. Counseling explains inheritance risks. Genetic Rare Disease Center+1

12. Chromosomal microarray (if indicated). Screens for copy-number changes when the presentation is complex or atypical. (General rare-disease workflow.) Genetic Rare Disease Center

13. Creatine kinase (CK). Usually normal here (helps exclude primary muscle disease). Genetic Rare Disease Center

14. Basic metabolic or infection screens as directed. Used to exclude other causes when features are atypical; not expected to explain this genetic syndrome. Genetic Rare Disease Center

D. Electrodiagnostic tests 

15. Full-field electroretinogram (ERG). The key test that can show electroretinal anomalies (reduced or altered retinal responses). This finding has been reported with the classic triad. ResearchGate

16. Electro-oculography (EOG) or visual evoked potentials (VEP) (as needed). Complements ERG if optic-nerve or retinal signal transmission is questioned. (General ophthalmic electrophysiology practice.) Lippincott Journals

17. Nerve-conduction studies/electromyography (EMG) only if the exam suggests another neuromuscular disorder; in this syndrome, these are often normal or non-diagnostic. Genetic Rare Disease Center

E. Imaging tests 

18. MRI of brain and orbits (eye sockets). Looks at the cranial nerves and extraocular muscles when ophthalmoplegia is significant; literature in arthrogryposis notes cranial nerve hypoplasia/degeneration as a putative mechanism. Nature

19. Orthopedic imaging (X-rays) of hands/feet/spine. Documents joint positions and helps plan casting, splinting, or surgery. PM&R KnowledgeNow

20. Optical coherence tomography (OCT) and wide-field retinal imaging. Non-invasive pictures of the retina and optic nerve to correlate with ERG and track changes over time. (Standard ophthalmic assessment in conditions with ERG changes.) Lippincott Journals

Non-pharmacological treatments

Dietary molecular supplements

Supplements can support overall health; none “cure” AOLEAS. Always discuss with the child’s clinician.

1. Vitamin D3 – correct deficiency; supports bone/mineral health in limited mobility. Typical dosing: per labs/age. Function/mechanism: calcium–phosphate balance; bone mineralization. SAGE Journals

2. Calcium – only if dietary intake is low. Mechanism: bone strength. Caution: avoid over-supplementation. SAGE Journals

3. Omega-3 fatty acids – general anti-inflammatory and cardiometabolic support; may help dry eye symptoms in some. Mechanism: eicosanoid modulation/tear film quality. EyeWiki

4. Multivitamin (age-appropriate) – covers gaps due to feeding challenges. Mechanism: micronutrient sufficiency. SAGE Journals

5. Iron (if iron-deficiency anemia) – improves energy and development when indicated by labs. Mechanism: hemoglobin synthesis. SAGE Journals

6. B-complex (if documented deficiency) – supports energy metabolism. Mechanism: co-factors for mitochondrial/enzymatic pathways. SAGE Journals

7. Magnesium (dietary or supplement if low) – muscle and nerve function; constipation relief at low doses. Mechanism: neuromuscular transmission; osmotic laxative effect (form-dependent). SAGE Journals

Immunity booster / regenerative / stem-cell drugs

There are no proven stem-cell or regenerative drug treatments for AOLEAS. Below are general clinical measures sometimes called “immune boosters,” framed realistically. Always consult the treating team.

1. Routine childhood vaccinations – strongest, proven “immune booster.” Dose: per schedule. Function: prevents serious infections that interrupt rehab/surgery. Mechanism: adaptive immunity. SAGE Journals

2. Vitamin D repletion (if low) – supports immune function and bone health. Dose: per labs. Mechanism: immunomodulatory effects of vitamin D receptors. SAGE Journals

3. Seasonal influenza vaccine – reduces respiratory illness burden. Dose: annual. Mechanism: strain-targeted immunity. SAGE Journals

4. Nutritional optimization – high-protein, micronutrient-adequate diet supports wound/soft-tissue recovery after casting/surgery. Mechanism: substrate for repair. jposna.org

5. Hygiene and infection-prevention practices – hand hygiene, dental care. Mechanism: reduce pathogen exposure/inflammation. SAGE Journals

6. Sleep optimization – regular sleep supports immune resilience and rehab participation. Mechanism: neuroendocrine–immune regulation. SAGE Journals

Surgeries

Surgery is common in AMC phenotypes and may be needed for feet, knees, hips, spine, eyelids, and eye alignment. Choice and timing are individualized.

1. Ponseti casting ± percutaneous Achilles tenotomy for clubfoot; bracing
   Procedure: serial casts; small tendon cut if needed; long-term bracing. Why: correct foot shape for standing/walking with less invasiveness. PMC+1

2. Soft-tissue releases/tendon transfers for joint contractures
   Procedure: lengthen tight tendons/capsule; sometimes transfer tendons to improve function. Why: increase range and improve hand/arm/leg use. jposna.org

3. Scoliosis surgery (selected cases)
   Procedure: spinal instrumentation/fusion when curves are severe/progressive. Why: posture, comfort, lung function. jposna.org

4. Ptosis repair (levator resection or frontalis sling)
   Procedure: lift droopy lids; sling uses brow muscle to raise eyelid when levator is weak. Why: clear visual axis, prevent amblyopia, protect cornea (balanced to avoid exposure). PMC+1

5. Strabismus surgery (selected)
   Procedure: adjust eye muscles to improve alignment. Why: reduce deviation and improve comfort/field; results vary in CPEO-like patterns. Medscape

Frequently Asked Questions

1. Is there a cure?
   No single medicine cures AOLEAS. Care focuses on therapy, bracing, and selected surgeries to improve function and protect vision. BMJ Journals+1

2. Will my child walk?
   Many children with AMC phenotypes walk with or without aids after early casting/bracing and ongoing therapy; outcomes vary by severity. jposna.org

3. Can eye movement improve?
   Ophthalmoplegia often persists; goals are safe eyelid position, ocular surface protection, and better alignment/comfort. PMC+1

4. What is an ERG and why do it?
   ERG measures retinal function. In this syndrome, ERG can be abnormal and guides low-vision planning and follow-up. BMJ Journals

5. Which therapy matters most?
   A consistent home program plus serial casting/bracing when needed offers the biggest gains. PMC+1

6. Are stem cells helpful?
   No proven stem-cell therapy exists for AOLEAS; avoid unregulated treatments. SAGE Journals

7. Is surgery always required?
   Not always, but many children need at least foot or eyelid procedures; timing is individualized. jposna.org+1

8. Will glasses fix eye movement limits?
   Glasses do not restore eye muscle function but can correct refractive error and sometimes help comfort (e.g., prisms in small deviations). EyeWiki

9. How often are checkups?
   Typically every 3–6 months in early years, then as guided by growth and needs. JPOSNA

10. Can school help?
    Yes—plans can add extra time, seating, and low-vision aids to support learning. Physiopedia

11. Will pain be constant?
    With good rehab, positioning, and sensible analgesia after procedures, most children participate well. SAGE Journals

12. Is AMC the same as cerebral palsy?
    No. AMC describes congenital contractures from many causes and is not the same as spastic CP. SAGE Journals

13. Should we pursue genetic testing?
    Yes, it helps confirm the diagnosis, guide counseling, and rule out overlapping syndromes. Genetic Rare Disease Center

14. What about sports?
    Adaptive physical activity is encouraged; therapists help choose safe options. SAGE Journals

15. What is the long-term outlook?
    Most adults with AMC are ambulatory, but upper-limb function may limit independence; early, coordinated care improves outcomes. jposna.org
