Autosomal Recessive Congenital Non-Lamellar and Non-Erythrodermic Ichthyosis

Autosomal recessive congenital non-lamellar and non-erythrodermic ichthyosis are rare genetic skin conditions present from birth. The skin makes too much thick outer layer (stratum corneum). This layer does not shed normally, so dry scales build up over most of the body. Some children are born in a tight shiny “collodion” membrane that peels off in weeks. “Nonlamellar, non-erythrodermic” means the scales are not in large plate-like sheets and the skin is not very red. Many genes can cause ARCI (for example TGM1, ALOX12B, ALOXE3, NIPAL4, CYP4F22, CERS3). These genes control the skin barrier lipids and the way skin cells stick and separate. The condition lasts for life, but good daily care can control dryness, thick scales, cracking, and infections. Genetic testing helps confirm the diagnosis and guide counseling for families. NCBI+2ScienceDirect+2

This condition is a rare, inherited skin disorder present from birth. “Autosomal recessive” means a child inherits one faulty gene from each parent. “Congenital” means present at birth. “Ichthyosis” means the skin makes too many layers (hyperkeratosis) and sheds poorly, leading to dry scales. In this specific form, the scales are not the large “plates” seen in lamellar ichthyosis (“non-lamellar”), and the skin does not show constant widespread redness (“non-erythrodermic”). Many babies are born with a shiny, tight covering called a collodion membrane that peels off in the first weeks. After that, the skin shows fine to moderate scaling with little or no redness. The problem lies in the skin barrier lipids and proteins (like ceramides and the cornified envelope) that normally “seal” the outer skin; when they don’t form correctly, water is lost and flakes build up. This phenotype sits between the classic ends of the ARCI spectrum (lamellar ichthyosis with large plates and non-bullous CIE with red, fine scaling). GeneSkin+3NCBI+3Medical Journals+3

Research first highlighted a non-lamellar, non-erythrodermic ARCI phenotype in a Finnish family, mapped to chromosome 19p13.1-p13.2, confirming that this pattern is a recognized part of the ARCI spectrum. PubMed Central

Other names

• ARCI (non-lamellar, non-erythrodermic phenotype)

• Non-erythrodermic, non-lamellar ARCI (a mild phenotype within the ARCI spectrum)

• Mild ARCI (context-dependent shorthand used in clinics)

• Post-collodion mild ARCI (when preceded by a collodion membrane)

• Sometimes described in relation to nearby entities like self-improving collodion ichthyosis (SICI) when the skin improves substantially after birth (though SICI is a specific course). GeneSkin+1

Types

Because ARCI covers several patterns, doctors often describe phenotypic sub-types rather than strict “types” for this particular, milder presentation:

1. Classic non-lamellar, non-erythrodermic ARCI. Fine to moderate, gray-white scaling on most of the body with little/no redness after the collodion phase. PubMed Central

2. SICI-like course (self-improving collodion ichthyosis). Collodion at birth with major improvement over weeks to months; later, only mild fine scaling and minimal redness remain. Genes in the epidermal lipoxygenase pathway (e.g., ALOX12B, ALOXE3) are common. PubMed Central+1

3. Intermediate ARCI between LI and CIE. Non-lamellar scaling without the persistent, generalized redness of CIE; sits on the spectrum between lamellar ichthyosis (LI) and non-bullous congenital ichthyosiform erythroderma (CIE). Medical Journals+1

---

Causes

In ARCI, “causes” primarily means genes that guide the lipids and proteins of the outer skin barrier. Different genes can produce overlapping skin pictures.

1. TGM1 variants. Lower activity of transglutaminase-1, a “glue” enzyme for the skin barrier, can yield fine, non-lamellar scaling with minimal redness in some families. Nature+1

2. ALOX12B variants. A lipoxygenase that helps make skin lipids; common in SICI-like courses with mild scaling and little redness. PubMed Central

3. ALOXE3 variants. Works with ALOX12B in the lipid pathway; disruptions weaken the barrier and lead to fine scaling. OUP Academic

4. NIPAL4 (ichthyin) variants. A membrane protein linked to epidermal lipid handling; produces ARCI with variable redness—some patients show non-erythrodermic, fine scales. OUP Academic+1

5. CYP4F22 variants. A P450 enzyme in very-long-chain lipid metabolism; can present with collodion then relatively mild scaling. BioMed Central

6. PNPLA1 variants. A lipid remodeling enzyme; defects give dry, scaly skin with barrier leakiness without constant redness. BioMed Central

7. CERS3 variants. Ceramide synthase; poor ceramide production weakens water-proofing and causes fine scales. BioMed Central

8. ABCA12 hypomorphic variants. Transporter for lipids into lamellar granules; less severe changes can look like mild ARCI without constant redness (severe loss causes harlequin). BioMed Central+1

9. LIPN variants. Lipase in corneocyte lipid processing; milder presentations reported. BioMed Central

10. SDR9C7 variants. Oxidoreductase affecting barrier lipids; may show fine scaling with minimal erythema. BioMed Central

11. SULT2B1 variants. Sterol sulfotransferase affecting cholesterol sulfate balance and desquamation. BioMed Central

12. ELOVL4 variants (rare ARCI-like skin). Very-long-chain fatty acid elongation changes may contribute to barrier dysfunction and fine scaling. BioMed Central

13. Modifier genes. Background variants can soften or worsen redness and scale size in ARCI families, explaining non-erythrodermic courses. Medical Journals

14. Collodion membrane course. The way the collodion peels can “unmask” milder residual ichthyosis rather than severe, persistent forms. PubMed Central

15. Environmental dryness (low humidity). Dry climates accent water loss through the weak barrier, making scales more visible even without redness. (General ARCI care principle.) NCBI

16. Heat or sweating stress. A compromised barrier plus decreased sweating can worsen scaling without necessarily triggering erythema. MedlinePlus

17. Irritant soaps/detergents. Strip lipids and aggravate flaking in ARCI. (General barrier guidance.) NCBI

18. Missed emollients. Stopping moisturizers allows scales to build up quickly. (Standard ARCI management.) NCBI

19. Intercurrent skin infection. Can transiently change scaling patterns; after treatment, many patients revert to their non-erythrodermic baseline. (Clinical practice note consistent with ARCI care.) NCBI

20. Age-related changes. Some children improve after infancy (SICI-like), settling into a mild, non-erythrodermic pattern. ScienceDirect

Symptoms

1. Fine to moderate dry scales across the body, often gray-white and powdery rather than plate-like. PubMed Central

2. Little or no background redness after the newborn period. PubMed Central

3. History of a collodion membrane at birth that peeled within weeks. NCBI

4. Tightness or stiffness of skin in dry weather (barrier water loss). NCBI

5. Itching (variable). Often mild; worsens with dryness or heat. NCBI

6. Scaling more obvious on trunk and limbs; body folds may accumulate flakes. Medical Journals

7. Face and flexures relatively less red than in CIE. Medical Journals

8. Mild palm/sole thickening (palmoplantar keratoderma) in some. BioMed Central

9. Mild scalp scaling and dry hair; occasional patchy hair thinning. MedlinePlus

10. Heat intolerance (reduced sweating in some). MedlinePlus

11. Skin tightness around eyes/lips in infancy (from collodion), usually improving. NCBI

12. Fissures in very dry seasons (painful cracks if care lapses). NCBI

13. Cosmetic concern and social stress, even when redness is absent. (Quality-of-life findings common across ARCI.) Medical Journals

14. Stable course over years with seasonal ups and downs. NCBI

15. Generally normal growth and health when the condition is isolated (non-syndromic). NCBI

Diagnostic tests

A) Physical examination

1. Full-body skin check. The clinician looks at scale size, color, and distribution and checks for redness. Fine, non-plate-like scaling without persistent generalized redness points to the non-lamellar, non-erythrodermic ARCI phenotype. PubMed Central+1

2. History of collodion membrane. Parents describe a shiny film at birth that peeled within weeks; this supports ARCI and helps separate it from other childhood dry-skin conditions. NCBI

3. Hair, nails, palms/soles, ears, eyes. Doctors check for mild palm/sole thickening, nail changes, scalp scale, and any residual eyelid/lip changes from the newborn phase. MedlinePlus

4. Hydration status and fissures. Chronic water loss can dry lips and cause small cracks; recognizing this guides moisturizer choice and bathing advice. NCBI

5. Temperature and sweat clues. Heat intolerance or low sweating suggests barrier-related thermoregulation issues, common in ARCI. MedlinePlus

B) Manual (bedside) tests

6. Scale rub test. Gentle rubbing shows how firmly scales adhere; fine, powdery scales detach more easily than classic lamellar “plates.” This simple observation supports a non-lamellar pattern. (Bedside clinical technique consistent with ARCI phenotyping.) Medical Journals

7. Pinch elasticity test. Light pinching of skin evaluates elasticity and comfort; stiffness/tightness improves after emollients, confirming barrier dryness rather than deep inflammation. (General barrier assessment.) NCBI

8. Emollient response trial. Short trial of thick moisturizers helps confirm barrier-driven scaling (improves with lipids/occlusion) and distinguishes from inflammatory rashes. (Standard ichthyosis care approach.) NCBI

9. Scale pattern mapping. Clinicians note body areas with heavier vs. lighter flaking to separate this phenotype from CIE (more red) or LI (plate-like). Medical Journals+1

10. Family pedigree review. Drawing a family tree can reveal recessive inheritance (often unaffected parents, multiple siblings with similar skin), reinforcing ARCI. NCBI

C) Laboratory and pathological tests

11. Genetic testing panel for ARCI genes. The most informative test. Panels typically include TGM1, ALOX12B, ALOXE3, NIPAL4, CYP4F22, PNPLA1, CERS3, ABCA12, LIPN, SDR9C7 and others. Identifying biallelic variants confirms the diagnosis and may explain a mild, non-erythrodermic course. NCBI+1

12. Skin biopsy (rarely needed). If diagnosis is unclear, a small sample can show orthokeratotic hyperkeratosis with reduced barrier lipids and relatively little inflammation—features consistent with ARCI rather than eczema. (General ARCI histology.) Medical Journals

13. Basic labs during newborn care. If a collodion membrane was present, teams check hydration, electrolytes, and infection markers to manage early risks; later, labs are usually normal. IJORD

14. Targeted lipid analyses (research settings). Specialized labs can measure ceramide subclasses or lipid enzyme activity to study the barrier; not routine but explains mechanism. Medical Journals

15. Rule-out tests for look-alikes. When redness or itch confuses the picture, clinicians may run minimal labs to exclude eczema or psoriasis flares; persistent, lifelong diffuse scaling still favors ARCI. NCBI

D) Electrodiagnostic / physiologic tests

16. Transepidermal water loss (TEWL) measurement. A handheld probe quantifies water escaping from skin; elevated TEWL supports a leaky barrier typical of ARCI, even without redness. (Physiologic barrier testing used in research/tertiary centers.) Medical Journals

17. Corneometry (skin capacitance). Measures surface hydration; low readings match dry, scaly ARCI skin and improve after emollients, backing a barrier-centric diagnosis. (Physiologic assessment.) Medical Journals

18. Sweat/thermoregulatory tests (selected cases). When heat intolerance is prominent, clinicians may assess sweating patterns (e.g., thermoregulatory sweat testing) to document reduced sweating in some ARCI patients. MedlinePlus

E) Imaging tests

19. Dermoscopy. A polarized scope can magnify scale edges and follicular openings; it helps document non-lamellar scale architecture and exclude mite infestations or keratin plugs. (Clinical imaging adjunct.) Medical Journals

20. High-frequency ultrasound (advanced centers). May show a thickened stratum corneum with preserved deeper layers, supporting a keratinization disorder rather than dermal inflammation. (Adjunctive imaging in research/tertiary practice.)

Non-pharmacological treatments (therapies & daily care)

1) Twice-daily emollients after bathing
Description: After a short lukewarm bath, pat the skin damp (not dry) and apply a thick moisturizer to lock in water. Petrolatum, ceramide-rich creams, or urea-containing creams help soften and seal the barrier. Daily use reduces tightness, scale, itching, and cracking.
Purpose: Hydrate, reduce scaling, and improve skin comfort.
Mechanism: Occlusive and humectant ingredients decrease transepidermal water loss and improve corneocyte “shedding” so scale releases more evenly. ERN Skin+1

2) Regular bathing with safe additives
Description: Short baths (5–10 minutes) help hydrate and loosen scale. Some patients benefit from adding a small amount of bath oil, salt, or baking soda. For those with frequent infections, a clinician may suggest dilute bleach baths intermittently. Rinse well and moisturize immediately.
Purpose: Hydration and gentle scale release; lower bacterial load when needed.
Mechanism: Water swells the stratum corneum; mild antiseptic baths reduce Staphylococcus aureus and other microbes that colonize damaged skin. PubMed Central

3) Gentle mechanical descaling
Description: After soaking, use soft cloths, silicone scrub mitts, or a paraffin “soak-and-peel” routine to lift loose scale. Stop if the skin becomes sore or bleeds.
Purpose: Reduce thick build-up that causes fissures and pain.
Mechanism: Hydration plus gentle friction helps detach retained corneocytes without injuring living layers. PubMed Central

4) Eye surface protection and eyelid care
Description: Use preservative-free lubricating eye drops and ointments; protect from wind; seek early ophthalmology input. Severe eyelid turning-out (ectropion) may need taping or later surgery.
Purpose: Prevent exposure keratitis, pain, and vision problems.
Mechanism: Lubricants replace the tear film; taping and, when needed, surgery restore lid-globe contact. PubMed Central+1

5) Ear canal hygiene
Description: ENT clinicians can remove impacted scale periodically. At home, softening drops approved by your clinician may help. Avoid cotton swabs that push debris inward.
Purpose: Maintain hearing and prevent infections.
Mechanism: Removing keratin plugs restores sound conduction and lowers bacterial growth in trapped debris. PubMed Central

6) Heat and sweat management
Description: Wear light, breathable clothing; take cooling breaks; hydrate well; use fans or cooling towels during hot weather.
Purpose: Prevent overheating and heat exhaustion when sweat cannot escape through thick scale.
Mechanism: External cooling substitutes for reduced evaporative heat loss across the skin. PubMed Central

7) Infection prevention and early treatment
Description: Clean minor cracks with soap and water, apply emollients, and seek care for spreading redness, fever, or pus.
Purpose: Reduce cellulitis and impetigo.
Mechanism: A better barrier and quick care of breaks limits bacterial entry through fissures. PubMed Central

8) Nail, hand, and foot care
Description: Soak thick areas, use keratolytic creams (see drug section), and wear cushioned socks and roomy shoes. Podiatry can debride painful hyperkeratosis.
Purpose: Reduce pain, prevent fissures, and protect function.
Mechanism: Targeted scale reduction offloads pressure and improves skin flexibility. PubMed Central

9) Genetic counseling and family planning
Description: A genetics team can explain inheritance (25% recurrence risk for carrier parents), coordinate gene testing, and discuss options for future pregnancies.
Purpose: Inform family decisions and connect to support groups.
Mechanism: Confirming the gene helps prognostic counseling and links to research or trials when available. NCBI

10) Vitamin D screening and supplementation when deficient
Description: Patients with ichthyosis often have low vitamin D. Blood testing and clinician-directed replacement improve bone and muscle health and may modestly help skin comfort.
Purpose: Prevent rickets/osteomalacia and support general health.
Mechanism: Correcting deficiency normalizes calcium-phosphate metabolism; case series suggest symptom relief in some patients. Medical Journals+2PubMed+2

Dietary molecular supplements

1) Vitamin D (when deficient)
Description & rationale: Vitamin D deficiency is common in ichthyosis; replacing low levels improves bone health and may lessen stiffness and discomfort.
Dose: Treat deficiency per clinician (e.g., loading then maintenance); monitor levels.
Function/mechanism: Restores normal calcium/phosphate balance; may modulate epidermal differentiation. Evidence includes cohort and case series showing high deficiency rates and symptomatic improvement. Medical Journals+2Medical Journals Sweden+2

2) Omega-3 fatty acids (fish oil/EPA-DHA)
Description & rationale: Anti-inflammatory lipids that may aid dry eye and general skin comfort; ichthyosis involves lipid pathway defects where essential fatty acids matter.
Dose: Typical nutrition doses per label; discuss interactions (e.g., anticoagulants).
Function/mechanism: Modify eicosanoid signaling and may improve tear film/skin barrier; evidence in ichthyosis is indirect or low level. First Skin Foundation+1

3) Ceramide precursors / oral ceramides
Description & rationale: Early data suggest oral ceramides may improve hydration and reduce water loss; most evidence is from cosmetic dermatology cohorts.
Dose: Product-specific; long-term safety data limited.
Function/mechanism: Provide building blocks for epidermal lipid lamellae. ScienceDirect

4) Balanced essential fatty acids (omega-6/omega-3)
Description & rationale: Some older studies show abnormal essential fatty acid patterns in ichthyosis; balanced intake may support barrier lipids.
Dose: Dietary sources (oils, nuts, fish) or supervised supplements.
Function/mechanism: Support synthesis of acylceramides crucial for barrier integrity. PubMed+1

5) General micronutrient adequacy
Description & rationale: Ensure adequate protein, zinc, and B-vitamins through diet; correct any lab-proven deficiencies.
Dose: Food-first; supplement only for proven deficits.
Function/mechanism: Supports keratin production and epidermal turnover; evidence is general, not ichthyosis-specific. BioMed Central

Procedures/surgeries

1) Surgical correction of cicatricial ectropion
What happens: Oculoplastic surgeons release tight lower (and sometimes upper) eyelids and graft healthy skin to restore eyelid position.
Why it’s done: To protect the cornea, relieve pain, and prevent vision loss when lubrication and taping are not enough.
Evidence: Case series report good outcomes with skin grafts; recurrence can occur and may need repeat procedures. PubMed Central+1

2) Release of constriction bands / syndactyly in severe keratoderma
What happens: Hand/foot surgeons release tight keratin bands that threaten digits and, if needed, separate fused skin between fingers or toes.
Why it’s done: To preserve blood flow and function when hyperkeratosis forms rings (pseudoainhum) or significant contractures.
Evidence: Reports in ichthyosis/keratoderma show surgery can help but recurrence risk exists; careful follow-up is needed. jaadcasereports.org+1

3) Canalplasty/meatoplasty for external ear canal stenosis
What happens: ENT surgeons widen a narrowed ear canal and remove scar tissue or bony growths; stenting or dilation may be used after surgery.
Why it’s done: To restore hearing and reduce infections when scale and scarring cause persistent blockage.
Evidence: Surgical reviews and series describe techniques and recurrence prevention strategies. Medscape+1

Practical prevention

1. Daily moisturize after every bath to lock in water and keep scale soft. ERN Skin

2. Avoid very hot water and harsh soaps; use gentle cleansers. PubMed Central

3. Protect from heat; rest, hydrate, and use cooling aids in hot weather. PubMed Central

4. Do not pick at dry plaques until after soaking; this prevents cracks. PubMed Central

5. Check eyes daily for redness or pain; use lubricants as advised. PubMed Central

6. Keep nails trimmed and smooth to avoid scratching injuries. PubMed Central

7. Treat small fissures early and seek care for signs of infection (spreading redness, pus, fever). PubMed Central

8. Schedule periodic ear checks for wax/scale removal to protect hearing. PubMed Central

9. Ask your clinician to screen for vitamin D deficiency and correct it if low. Medical Journals

10. Discuss pregnancy plans well before systemic retinoids; strict contraception is mandatory with acitretin and isotretinoin. FDA Access Data+1

---

When to see a doctor

See a dermatologist or primary clinician if the skin becomes very painful, develops yellow crusts or pus, or you get fever or spreading redness—these can mean infection. See an eye doctor urgently for eye pain, light sensitivity, reduced vision, or if your eyelids are turning out (ectropion). Ask ENT for blocked hearing or ear pain from scale build-up. If thick skin on hands/feet causes deep cracks or if fingers or toes look constricted, get specialist care. Finally, if you are considering pregnancy or new medicines, review retinoid risks and contraception requirements. PubMed Central+2PubMed Central+2

---

What to eat (and avoid)

Eat a balanced diet with enough protein, healthy fats, fruits, vegetables, and whole grains. Include foods rich in omega-3 fatty acids (fish like salmon, sardines; plant sources like flax or chia) and ensure vitamin D adequacy through safe sunlight, diet, or supplements if your doctor finds a deficiency. Avoid crash diets that limit essential fats, since the skin barrier needs lipids to function. There is no proven “ichthyosis diet,” but good nutrition supports skin renewal and overall health. Medical Journals+1
