Johnston-Aarons-Schelley syndrome is the name used for a single recessive genetic syndrome first described in a 1993 medical report. Babies had three main findings from birth: (1) multiple joint contractures (the joints are stuck in bent or straight positions—this pattern is called arthrogryposis), (2) very thick, scaly, fissured skin (hyperkeratosis), and (3) severe under-development of the posterior columns of the spinal cord, which are nerve tracts important for position and vibration sense. The original report suggested a poor (lethal) early-infant prognosis. Since that report, medical rare-disease registries note no additional confirmed cases, so our knowledge is based almost entirely on that publication and summary listings. PubMed+2Genetic Rare Disease Center+2
Johnston–Aarons–Schelley syndrome is the historic name for a lethal arthrogryposis–hyperkeratosis syndrome. Babies are born with many stiff joints (contractures) and very thick, cracked skin (hyperkeratosis). In the only medical report, two brothers were affected; one had severe underdevelopment of the dorsal spinal roots and posterior spinal columns on autopsy. No additional confirmed cases have been published since that 1993 description, and major rare-disease registries list it as an exceptionally rare, likely lethal disorder of early infancy. MeSH Linked Data+3PubMed+3Genetic Rare Disease Center+3
Arthrogryposis usually develops when a fetus moves too little in the womb (fetal akinesia). That lack of movement can be due to problems anywhere along the movement pathway—from the brain and spinal cord to the peripheral nerves and muscles—or from the environment around the fetus. In many arthrogryposis conditions, the nerves to the muscles don’t form or function normally; classic pathology papers and imaging reviews show injuries or underdevelopment in the spinal cord’s motor columns or roots. The 1993 Johnston report adds severe hypoplasia of dorsal roots/posterior columns to this picture, consistent with a neurogenic cause and profound immobility before birth. PubMed+2AJNR+2
It is an extremely rare, likely inherited condition in which a baby is born with stiff joints, very thick skin, and a major wiring problem in part of the spinal cord. Because it has been reported only once in the literature and not followed by new families, doctors treat it as a lethal arthrogryposis-hyperkeratosis syndrome described by Johnston, Aarons, and Schelley.

Sometimes listed in disease lists as “Johnston–Aarons–Schelley syndrome.” Wikipedia
Note: These names refer to the same tiny cluster of patients reported in 1993; no widely accepted gene name or broader subtype catalog exists yet. PubMed+1
Types
Because only one family (or a very small number of infants) has been formally described, no validated “types” or sub-types are established. When databases mention “lethal form,” they are reflecting that the original description carried a fatal early-infant course, not that non-lethal types are known. In practice, clinicians would consider this phenotype within the spectrum of lethal arthrogryposis disorders until more cases clarify distinct categories. Genetic Rare Disease Center
Causes
Important context: The exact gene is unknown. The 1993 authors proposed a recessive inheritance because multiple affected siblings were born to healthy parents, which fits autosomal-recessive patterns. With no follow-up cases, detailed molecular proof is unavailable. So below are causes/mechanisms that explain how such a syndrome could arise, grounded in what we see (joint contractures, hyperkeratosis, posterior column hypoplasia) and by analogy to better-known conditions with similar features. Each item is phrased as a mechanism a single, as-yet-unknown gene defect could disrupt; they are plausible paths, not proven for this specific label. PubMed+1

Symptoms and signs
Because the condition was reported in newborns in a lethal context, symptoms are present at birth and severe:
Fixed or very stiff joints in arms and legs (arthrogryposis). Limbs cannot move through a normal range. PubMed+1
Thick, scaly, cracked skin (hyperkeratosis). The skin barrier looks heavy and fissured. Genetic Rare Disease Center
Weak or absent reflexes tied to position sense (because posterior columns carry proprioception). Clinically difficult in a newborn but inferred from neuropathology. PubMed
Poor spontaneous movement before and after birth, noticed as decreased kicks in late pregnancy or limited postnatal motion. Genetic Rare Disease Center
Feeding difficulty (seen in many lethal arthrogryposis syndromes). Genetic Rare Disease Center
Breathing problems due to weak muscles and chest wall stiffness or central control issues. Genetic Rare Disease Center
Early failure to thrive because of severe systemic involvement. Genetic Rare Disease Center
Contractures of fingers and toes, not just large joints. Genetic Rare Disease Center

Diagnostic tests
Key idea: Because this condition is almost only known from the 1993 report, testing aims to (a) document the triad (contractures + hyperkeratosis + posterior column hypoplasia), (b) rule out better-known look-alike disorders, and (c) seek a genetic answer with broad sequencing—even though a specific gene is not yet defined. PubMed+1
A) Physical examination
Newborn joint exam and range-of-motion mapping. Confirms arthrogryposis pattern across shoulders, elbows, hips, knees, wrists, fingers, and toes. (Arthrogryposis work-up principle.) Genetic Rare Disease Center
Skin inspection for hyperkeratosis and fissuring. Notes thickness, scaling, cracks, and risk of infection or fluid loss. Genetic Rare Disease Center

Basic labs for infection/inflammation if skin fissures are present (CBC, CRP) to catch secondary complications. (General care principle.) Genetic Rare Disease Center
Metabolic screening panel. Helps rule out metabolic conditions that can mimic multisystem congenital presentations. (Rare-disease work-up principle.) Genetic Rare Disease Center
Molecular testing (exome/genome sequencing). Although no specific gene is established, broad sequencing in affected infants (or parental trio) is appropriate to search for a novel recessive variant; this is standard in undiagnosed lethal arthrogryposis. Genetic Rare Disease Center
Neuropathological examination (post-mortem, when appropriate). The 1993 report documented severe hypoplasia of the posterior columns, the key diagnostic clue anchoring this syndrome’s definition. PubMed
D) Electrodiagnostic tests
Nerve conduction studies (NCS) to assess sensory responses; posterior-column pathway issues may correlate with absent or abnormal sensory signals (in practice, often limited in neonates). PubMed

Prenatal ultrasound and/or fetal MRI (in future pregnancies). May detect decreased fetal movements (a clue to arthrogryposis) and severe contractures before birth, prompting genetic counseling and specialized delivery planning. (Arthrogryposis prenatal practice.) Genetic Rare Disease Center
Non-pharmacological treatments (therapies & other measures)
(Because this condition is lethal in early infancy, these measures focus on comfort, skin protection, feeding, and family-centered support. Where specific evidence exists—for arthrogryposis rehab, ichthyosis care, or neonatal palliative care—I cite it.)
High-humidity incubator care
Keeping the baby in a warm, humidified incubator reduces water and heat loss through the cracked skin, lowers metabolic stress, and helps prevent dehydration and skin fissuring. Close monitoring of temperature, fluids, and electrolytes is essential in the first days. This is standard for severe neonatal ichthyosis and severe barrier defects. ERN SkinFrequent sterile emollient application
Thick layers of sterile white petrolatum (or similar occlusive ointments) several times a day soften scales, reduce fissures, and restore some barrier function; guidelines also warn that neonates may absorb topical products more readily, so teams choose simple, inert formulations. ERN Skin+1Gentle bathing and softening soaks
Short, lukewarm baths followed by immediate emollient “seal-in” can decrease scaling and itching. Harsh soaps and vigorous rubbing are avoided to prevent erosions and infection risk in fragile neonatal skin. Akademiska SjukhusetOcular lubrication and eyelid care
If eyelids can’t fully close (from contractures or skin tightness), scheduled eye lubrication (non-medicated artificial tears/ointments) and eyelid protection prevent exposure keratopathy. This step is routine in congenital ichthyosis protocols. ERN SkinPositioning and gentle splinting for comfort
Neutral-positioning, soft splints, and frequent, gentle repositioning help protect joints, relieve pressure points, and improve comfort. In non-lethal arthrogryposis these are part of early rehab; here they are adapted primarily for comfort and skin protection. PMCPhysiotherapy-informed handling
Therapists coach families on safe handling, passive range-of-motion within comfort limits, and bed-support strategies that minimize skin shear. In arthrogryposis, early, expert therapy supports function; in a lethal neonatal setting, it focuses on minimizing pain and preventing sores. PMCMeticulous infection-prevention nursing
Fragile skin and poor mobility raise infection risk. Strict hand hygiene, gentle adhesive use (or none), and early attention to skin cracks lower secondary infection risk—principles drawn from ichthyosis and NICU skin care. Akademiska SjukhusetThermoregulation and fluid balance protocols
Continuous monitoring of temperature and weight/urine output helps prevent dehydration and hypothermia—a key concern in barrier-loss conditions. ERN SkinFeeding support (breast milk prioritized)
Lactation support, paced feeding, and NG feeds when needed protect from aspiration and malnutrition. Perinatal palliative care frameworks emphasize maximizing comfort and family goals while optimizing nutrition as tolerated. Frontiers+1Pain and distress assessment (non-drug)
Use validated neonatal comfort scales; non-pharmacologic soothing (skin-to-skin when safe, swaddling modifications, gentle voice, low-stimulus rooms) can reduce distress. These are pillars of neonatal palliative care. PMCEye-safe humidified oxygen (if needed)
When breathing is labored, low-flow humidified oxygen may ease work of breathing without causing ocular dryness or skin cracking around tubing areas. This belongs to supportive care; escalation decisions remain values-based. PMC+1Family-centered palliative planning
Early, structured conversations clarify goals (comfort-focused vs. trial of intensive support), preferred environments, and spiritual/cultural needs—including Islamic bioethical guidance where relevant. ACOG+1Psychological support for parents
Dedicated psychosocial care reduces trauma and helps parents participate in care and memory-making—standard in neonatal palliative pathways. FrontiersEthical consultation in the NICU
When decisions about initiating or withdrawing intensive supports arise, ethics teams help align care with best interests and family values, consistent with international NICU end-of-life guidance. PMC+1Oral care and moisture maintenance
Regular oral swabs with sterile water and barrier ointments prevent cracking and bleeding in mucosa—borrowed from NICU comfort bundles. PMCPressure-injury prevention
Low-shear bedding, frequent position changes, and protective dressings over bony points are adapted from NICU skin-care protocols and severe ichthyosis care. Akademiska SjukhusetTemperature-neutral environment (low TEWL)
Maintaining a thermoneutral room or isolette reduces transepidermal water loss and physiologic stress in severe barrier disorders. ERN SkinEye/ear/nose checks with early referrals
Regular ENT and ophthalmology checks catch exposure-related injuries early—standard in congenital ichthyosis teams. ERN SkinParent education and home-going plans (when appropriate)
If discharge is considered, families receive training on emollients, gentle handling, feeding cues, and when to seek urgent attention—principles adapted from ichthyosis and palliative-home-care guidance. Akademiska Sjukhuset+1Memory-making and bereavement support
Hand/footprints, photos, and rituals are integral to perinatal palliative care, supporting family grief and meaning-making. Frontiers
Drug treatments
There are no disease-modifying medications for Johnston–Aarons–Schelley syndrome. Any medicines used are symptom-guided NICU and dermatology standards for babies with severe skin barrier loss and contractures. Doses are individualized by neonatal specialists. (Below, “class/dose/time/purpose/mechanism/side effects” are given in plain language; exact dosing must follow neonatal formularies.)
White petrolatum (topical emollient; frequent applications)
Class: occlusive emollient. Timing: after every bath and as needed. Purpose: restore barrier, reduce fissures/pain. Mechanism: forms inert, occlusive layer to reduce transepidermal water loss. Side effects: minimal; watch for rare contact issues and increased absorption risk with additives—hence simple petrolatum is preferred in neonates. Evidence: first-line in congenital ichthyosis/neonatal barrier defects. ERN Skin+1Topical liquid paraffin/soft paraffin mixes
Similar to petrolatum; used to soften thick scale and reduce cracking. Avoid fragranced or complex formulations in neonates. Akademiska SjukhusetTopical glycerol-based moisturizers
Class: humectant emollients. Purpose/mechanism: draw water into outer skin layers and improve flexibility; often layered under an occlusive. Caution: avoid stinging on erosions. Akademiska SjukhusetTopical urea (low-strength), selective use
Class: keratolytic/humectant. Purpose: soften hyperkeratosis in limited areas. Mechanism: breaks hydrogen bonds in keratin. Caution: guidelines advise avoiding urea on inflamed/flexural/eroded skin and using great caution in neonates. Akademiska SjukhusetLubricating eye ointments/drops (non-medicated)
Class: ocular lubricants. Purpose: protect cornea if eyelids don’t close fully. Side effects: transient blur with ointments. Standard in ichthyosis neonatal care. ERN SkinAcetaminophen (paracetamol; neonatal dosing by weight/interval)
Class: analgesic/antipyretic. Purpose: pain relief for skin fissures or procedures. Mechanism: central COX modulation. Cautions: dose carefully to avoid hepatotoxicity. Used across NICUs for mild pain. PMCOral sucrose for minor procedures
Class: analgesic adjunct in neonates. Purpose: brief pain reduction. Mechanism: endogenous opioid pathway activation. Side effects: minimal when used properly. Standard in NICU comfort bundles. PMCOpioids (e.g., morphine; NICU protocols)
Class: opioid analgesic. Purpose: significant pain/dyspnea relief in comfort-focused care. Mechanism: μ-receptor agonist. Cautions: respiratory depression, constipation—specialist dosing essential. Widely used in neonatal palliative care when indicated. PMCTopical barrier pastes (zinc oxide) for diaper area
Class: barrier protectant. Purpose: prevent maceration and secondary infection. Side effects: minimal; avoid aggressive removal. Included in dermatology/NICU skin-care practice. Akademiska SjukhusetTopical antiseptics (e.g., chlorhexidine aqueous) for limited use
Purpose: reduce bacterial load in fissures; avoid alcohol-based products on large areas in neonates to limit absorption/irritation. Use sparingly per clinician guidance. Akademiska SjukhusetSystemic antibiotics (when infection is suspected/confirmed)
Class: per culture and sepsis protocols. Purpose: treat skin or systemic infection. Mechanism/side effects: drug-specific; stewardship is key. NICU sepsis pathways apply. PMCAntifungal agents (topical/systemic per indication)
Used for candidal intertrigo or thrush when present; chosen and dosed per neonatal guidance. PMCTopical corticosteroids (low-potency, limited areas)
Purpose: short bursts for inflamed, itchy plaques causing distress. Caution: neonatal skin has high absorption—use only under dermatology supervision. Akademiska SjukhusetHumidified oxygen
Class: supportive therapy (not a drug, but administered therapy). Purpose: ease dyspnea/work of breathing. Risks: dryness if not humidified; monitor saturation and comfort goals. PMCAntiseborrheic emollient shampoos (non-medicated first-line)
For scalp scaling; avoid keratolytics and fragrances in neonates. Akademiska SjukhusetVitamin D supplementation (standard neonatal nutrition)
Given per local neonatal guidelines to support bone/immune health; not disease-specific but part of routine care when feeding is established. PMCElectrolyte/IV fluid therapy
To correct dehydration from transepidermal water loss and feeding difficulties; individualized by NICU teams. PMCAntipruritic strategies (non-sedating antihistamines—case by case)
In older infants with ichthyosis, these may reduce itch; in neonates, use great caution and only if clearly indicated. Dermatology oversight recommended. Akademiska SjukhusetSystemic retinoids: generally avoided in neonates
Retinoids can thin hyperkeratosis in certain congenital ichthyoses later in life, but consensus statements emphasize careful selection, specialist oversight, and significant adverse-effect potential; they are not routine neonatal therapy. PMCPalliative sedation in refractory distress (specialist-led)
When suffering is extreme and not controllable, palliative-care teams may consider proportionate sedation under strict protocols aligned with family values and ethics guidance. PMC+1
Note: Exact drug names/doses are intentionally not listed here for neonates because they must be individualized by NICU specialists. The focus is on what classes are used and why, based on broader neonatal/dermatology/palliative evidence.
Dietary molecular supplements
There are no syndrome-specific supplements proven to change outcomes. Nutrition in this setting is about tolerance, growth, and comfort:
Human milk (mother’s or donor) — best tolerated, supports immunity and skin healing; fortified if growth is inadequate. PMC
Human-milk fortifiers — add protein/minerals to meet NICU growth needs, per dietitian. PMC
Medium-chain triglyceride (MCT) supplementation — improves caloric density and absorption in some infants with feeding limits. PMC
Standard neonatal multivitamins — maintain micronutrients during NG/limited oral feeds. PMC
Vitamin D — routine neonatal supplementation as above. PMC
Vitamin A/E (dietary levels only) — no high-dose therapy; aim for adequate intake to support epithelial health; avoid excess. Akademiska Sjukhuset
Electrolyte-balanced fluids — not a supplement per se, but critical to safely accompany feeds in babies with high transepidermal water loss. ERN Skin
Iron (standard timing if clinically appropriate) — per neonatal anemia prevention protocols; defer in acute infection. PMC
Zinc (dietary adequacy) — ensures skin repair and immune support; avoid pharmacologic doses without indication. Akademiska Sjukhuset
Thickened feeds (texture modifications) — for aspiration risk; guided by speech/feeding therapy. PMC
Immunity-booster / regenerative / stem-cell drugs
No credible evidence supports immunity-boosting agents, regenerative drugs, or stem-cell therapies for this lethal neonatal syndrome. Offering such products would be experimental and ethically inappropriate outside a rigorously approved research protocol. Neonatal palliative and ethics guidance instead focuses on comfort, family values, and proportional use of supportive therapies. PMC+2ACOG+2
Surgeries
In typical, non-lethal arthrogryposis, orthopedic surgeries (soft-tissue releases, tendon transfers, osteotomies), serial casting, and bracing can improve function over time. However, in Johnston–Aarons–Schelley syndrome, the reported course is lethal in early infancy, so surgery is generally not pursued; priorities are comfort and skin protection. If procedures occur, they are comfort-oriented (e.g., central lines for nutrition, gentle splinting/casting for positioning) rather than reconstructive operations. JPOSNA+1
Prevention
Because the exact cause and inheritance are unknown (the original report suggested a single-gene recessive trait but no gene was identified), true “prevention” is limited. Practical steps include: preconception/antenatal counseling for affected families; detailed fetal ultrasounds to look for decreased movement/contractures; ethical planning for delivery and postnatal care if severe findings are seen; avoiding unproven therapies; and ensuring delivery at centers with NICU/dermatology/palliative expertise. PubMed+1
When to see doctors
During pregnancy: if scans show reduced fetal movements, joint contractures, or thickened skin, request referral to maternal–fetal medicine and neonatal teams to plan delivery and care goals. Frontiers
After birth: immediate care in a NICU with dermatology, orthopedics/rehab, and palliative care support is recommended to manage skin barrier, feeding, and comfort. PMC+1
What to eat and what to avoid
Prefer: breast milk (mother’s or donor) and carefully advanced feeds designed by the NICU dietitian; small, frequent feeds to reduce effort; adequate fluids; standard neonatal vitamins and minerals. PMC
Avoid: forcing feeds that cause distress or aspiration; high-dose “immune boosters” or supplements without medical indication; fragranced or additive-heavy topical products that could be absorbed through fragile skin. Akademiska Sjukhuset
FAQs
1) Is there a cure?
No. Only supportive and palliative care are available, tailored from arthrogryposis/ichthyosis and neonatal comfort guidelines. PMC+2ERN Skin+2
2) How rare is it?
Extremely rare—only one published family (two brothers) in 1993; registries note no additional confirmed cases since then. PubMed+1
3) Is the gene known?
No. The 1993 paper suggested recessive inheritance, but no causative gene was identified. PubMed
4) How is it different from “regular” arthrogryposis?
“Regular” arthrogryposis spans many conditions and severities; this named syndrome combines severe contractures with marked hyperkeratosis and is lethal in early infancy. JPOSNA
5) Are retinoid drugs used for the skin?
Not in neonates with this presentation. Retinoids have roles later in specific ichthyoses but carry significant risks; they’re not routine neonatal therapy. PMC
6) Can surgery fix the joints?
In non-lethal arthrogryposis, surgeries can improve function. In this lethal neonatal syndrome, care is comfort-focused; reconstructive surgery is generally inappropriate. JPOSNA
7) What does palliative care mean here?
A specialized, compassionate approach prioritizing comfort, relief of distress, and family goals—alongside or instead of life-prolonging treatments. PMC+1
8) Is intensive care ever used?
Some families and teams may trial assisted breathing or feeding while assessing comfort and response, using structured, values-based decision-making and ethics support. Frontiers
9) How do we protect the eyes and skin?
Humidified incubator, frequent simple emollients, eye lubrication, gentle handling, and infection-prevention nursing. ERN Skin+1
10) What infections are a risk?
Skin barrier breakdown increases bacterial and fungal infection risk; clinicians use hygiene bundles and treat proven infections per NICU protocols. Akademiska Sjukhuset
