Alpha-N-acetylgalactosaminidase deficiency is a very rare inherited (runs in families) disease. It happens when the body does not make enough of one cleaning enzyme inside cells, called alpha-N-acetylgalactosaminidase, or “α-NAGA.” This enzyme normally lives in tiny recycling rooms inside our cells called lysosomes. Its job is to cut off a small sugar (“GalNAc”) from larger molecules called glycoproteins and glycolipids so the cell can reuse or remove them.
Alpha-N-acetylgalactosaminidase deficiency is a very rare, inherited condition. It happens when the body is missing or has very low activity of a lysosomal enzyme called alpha-N-acetylgalactosaminidase (short: alpha-NAGA). Lysosomes are tiny recycling centers inside cells. Alpha-NAGA normally helps break down certain glycoproteins and glycolipids (these are proteins and fats with sugar chains on them). When this enzyme is not working well, those sugar-containing molecules build up inside cells. Over time, that buildup harms cells and tissues, especially the nervous system, skin, and other organs. The condition is autosomal recessive (both parents carry one non-working copy of the NAGA gene on chromosome 22). There are three clinical types: Type I (infantile, most severe, early neurodegeneration), Type II (adult, “Kanzaki disease,” usually milder with skin angiokeratomas and neuropathy), and Type III (intermediate). MedlinePlus+2MedlinePlus+2
When α-NAGA is missing or too weak because of changes (variants) in the NAGA gene, those sugar-attached molecules pile up inside lysosomes. Over time, this buildup stresses and damages many types of cells, especially cells in the brain and nerves, and sometimes skin, ears, and other organs. That damage leads to the symptoms we see in this disease. The condition is autosomal recessive, which means a child gets the disease only if they inherit one changed NAGA gene from each parent. MedlinePlus
This disorder is part of a larger group called lysosomal storage diseases—conditions caused by failure of a lysosomal enzyme and the resulting storage of material that should have been broken down. Only a small number of patients have been reported worldwide. MedlinePlus+1
Other names
Schindler disease (umbrella name for the condition)
Kanzaki disease (often used for the adult, milder form)
NAGA deficiency / α-NAGA deficiency
Alpha-galNAc deficiency, Schindler type
Angiokeratoma corporis diffusum with glycopeptiduria
Schindler disease type 1 / type 2 / type 3
These names all refer to the same enzyme problem or its clinical subtypes. MedlinePlus
Types
Doctors group the condition into three clinical types based on age at onset and severity. The enzyme problem is the same; the timing and symptoms differ.
Type I (infantile, severe) – Babies look normal at birth. Late in the first year, development slows or stalls. Skills that were gained may be lost (developmental regression). Weak muscle tone (hypotonia), seizures, and progressive brain and nerve problems appear. This type is the most severe. MedlinePlus+2Orpha.net+2
Type II (adult, mild) — also called Kanzaki disease – Often found in adulthood. People may have mild learning or thinking problems, sensorineural hearing loss, peripheral neuropathy (numbness, tingling, weakness in hands/feet), and angiokeratomas (small dark red skin spots from clusters of dilated blood vessels). Limb swelling (lymphedema) can happen. Cardiac thickening has been reported in some cases. This is the mildest form. EJCRIM+3MedlinePlus+3Orpha.net+3
Type III (intermediate) – Features sit between types I and II. Developmental, speech, and language delay, seizures beginning in infancy, and sometimes autism-spectrum features are reported. Some people have bone or joint pain (lower back, hips, knees). NCBI+1
Causes
In this condition, the root cause is genetic—harmful variants in the NAGA gene. Below are 20 simple ways to describe the biological causes and risk situations that result in the same end-problem: lack of working α-NAGA enzyme and storage of glycoproteins/glycolipids in lysosomes.
Pathogenic variants (mutations) in NAGA – The direct cause; change the enzyme so it cannot work. MedlinePlus
Missense variants – One amino acid is swapped for another, altering the enzyme shape and activity. MedlinePlus
Nonsense variants – A “stop” signal appears too early; a shortened, nonworking enzyme is made. MedlinePlus
Frameshift variants – Small insertions/deletions shift the reading frame and wreck the enzyme. MedlinePlus
Splice-site variants – Incorrect cutting and pasting of the gene message leads to faulty enzyme. MedlinePlus
Large deletions/duplications of NAGA – Missing or extra gene segments prevent normal enzyme production (rare but possible among lysosomal diseases). MedlinePlus
Compound heterozygosity – Two different harmful variants (one from each parent) together cause disease. MedlinePlus
Homozygosity – The same harmful variant inherited from both parents (more likely in consanguinity). MedlinePlus
Protein misfolding – Variant changes make the enzyme misfold and get degraded before reaching lysosomes. MedlinePlus
Defective lysosomal targeting – The altered enzyme may not be properly delivered to lysosomes. Nature
Loss of catalytic site function – The active “cutting” site is changed; GalNAc sugar cannot be removed. Nature
Reduced enzyme stability – Even if made, the enzyme breaks down faster than normal. Nature
Autosomal recessive inheritance – Needing two faulty copies explains why carrier parents are healthy. MedlinePlus
Lysosomal storage cascade – Accumulated glycoproteins/glycolipids trigger cell stress and dysfunction. MedlinePlus
Neural vulnerability – Brain and nerve cells are especially sensitive to lysosomal stress, so neuro symptoms dominate. MedlinePlus
Tissue-specific accumulation – Skin vessels, inner ear, and peripheral nerves can store material and fail over time (explains angiokeratomas, hearing loss, neuropathy). MedlinePlus+1
Founder effects – In some communities, one historical variant may be more common, raising local risk (pattern seen in many rare lysosomal diseases). MedlinePlus
Limited residual activity – Tiny leftover enzyme activity may produce milder, later disease (type II/III). MedlinePlus
Modifier genes/environment – Other genes or health factors may modify severity, even with the same NAGA variant. MedlinePlus
Under-recognition/late diagnosis – Not a biological cause, but it explains why symptoms advance before the condition is identified; it is extremely rare and often missed. MedlinePlus
Common symptoms and signs
Symptoms vary by type and even within families. Not everyone has all features.
Developmental delay – Sitting, standing, talking, and learning happen later than usual because brain cells are affected by stored material. (Type I/III) MedlinePlus
Developmental regression – A child may lose skills they had before as nerve damage progresses. (Type I) MedlinePlus
Low muscle tone (hypotonia) – The body feels “floppy” in infancy due to impaired nerve-muscle communication. (Type I) MedlinePlus
Seizures – Abnormal bursts of brain activity; may start in infancy in the severe and intermediate forms. MedlinePlus
Hearing loss (sensorineural) – Inner-ear nerve damage leads to gradual hearing problems, especially in type II. MedlinePlus
Peripheral neuropathy – Numbness, tingling, burning, or weakness in hands and feet because long nerves are vulnerable. (Type II) MedlinePlus
Angiokeratomas – Small, dark red to purple skin spots made of dilated blood vessels with rough surface; often on trunk or groin. (Type II hallmark) MedlinePlus
Lymphedema – Swelling of limbs from poor lymph drainage; reported in adult cases. (Type II) EJCRIM
Balance problems or vertigo – Inner-ear involvement and neuropathy can cause unsteadiness. (Type II) EJCRIM
Mild cognitive impairment – Subtle thinking or memory difficulties in the adult form. (Type II) MedlinePlus
Autism-spectrum features – Social or communication challenges described in some with type III. NCBI
Speech and language delay – Words and sentences come late; related to brain network involvement. (Type III) NCBI
Coarse facial features and dental anomalies – Widely spaced or missing teeth (hypodontia) and “coarse” facial appearance can be seen. MedlinePlus
Joint or bone pain – Pain in lower back, hips, or knees has been described in type III. NCBI
Possible heart thickening (cardiomyopathy) – Some adult cases report heart muscle changes, likely from storage in heart cells. (Uncommon) EJCRIM
Diagnostic tests
Doctors combine history, examination, enzyme testing, and genetic testing to confirm the diagnosis. The enzyme and genetic tests are the most important.
A) Physical examination
General growth and development check – Looks for delayed milestones or loss of skills in infants/children; guides urgent evaluation for a lysosomal disorder. (Type I/III) MedlinePlus
Neurologic exam – Reviews tone, reflexes, coordination, sensation, and strength; helps document hypotonia, spasticity, neuropathy, or ataxia. MedlinePlus
Skin inspection for angiokeratomas – Identifies the classic dark, rough spots of type II on trunk/groin; their presence strongly suggests an adult lysosomal disease pattern. MedlinePlus
Ear and hearing bedside screen – Simple whisper or finger-rub tests flag possible hearing loss before formal audiology. MedlinePlus
Edema and lymph exam – Checks for limb swelling (lymphedema) and lymph node changes reported in adult cases. EJCRIM
B) Manual / bedside tests
Developmental milestone checklist – Structured questions (e.g., Ages & Stages) to capture delays or regression over time. MedlinePlus
Bedside sensory testing – Light touch, pin-prick, vibration (tuning fork) in hands/feet for peripheral neuropathy signs. MedlinePlus
Bedside hearing screen – Tuning-fork (Rinne/Weber) helps suggest sensorineural hearing loss pending audiometry. MedlinePlus
Skin diascopy/dermoscopic look – Gentle glass slide pressure or dermoscope view supports the vascular nature of angiokeratomas while awaiting dermatology review. MedlinePlus
C) Laboratory and pathological tests
Leukocyte or plasma α-NAGA enzyme activity – Key test. Shows low or absent α-NAGA activity. Abnormal results drive genetic confirmation. MedlinePlus
Dried blood spot (DBS) enzyme assay – Screening approach when rapid testing is needed; low activity prompts full work-up. MedlinePlus
Urine oligosaccharide / glyco-conjugate analysis – Detects stored sugar-containing molecules that accumulate when α-NAGA is deficient. MedlinePlus
Targeted NAGA gene sequencing – Definitive test. Finds the exact variants; allows family testing and counseling. MedlinePlus
Expanded lysosomal disorder gene panel – Helpful when the presentation is unclear and several lysosomal diseases are possible. MedlinePlus
Skin biopsy (histology/electron microscopy) – May show storage vacuoles in skin cells and vessel walls, supporting a storage disorder in adult type with angiokeratomas. Nature
Basic labs for complications – General blood counts, liver/kidney tests, and lipids to look for secondary issues and to baseline overall health; these do not diagnose but help manage care. (General lysosomal disease practice) MedlinePlus
D) Electrodiagnostic tests
Nerve conduction studies and EMG – Measure speed and strength of nerve signals; can show axonal/demyelinating neuropathy in adults. EJCRIM
EEG (electroencephalogram) – Records brain waves; helps confirm and manage seizures in infantile/intermediate forms. MedlinePlus
E) Imaging tests
Brain MRI – Looks for brain atrophy or white-matter changes seen in severe neurodegenerative lysosomal disorders; supports type and severity but is not specific. ScienceDirect
Echocardiogram (heart ultrasound) – Screens for uncommon heart thickening reported in some adult cases with Kanzaki disease. EJCRIM
Non-pharmacological treatments (therapies & others)
These are core supportive strategies. They are chosen and adjusted by your care team based on age, type, and symptoms.

Drug treatments
There is no approved disease-modifying drug for NAGA deficiency yet. Medicines are used to control symptoms and complications. Doses and timing are individualized—clinicians adjust for age, weight, kidney/liver function, interactions, and goals. The examples below are commonly used classes with typical adult starting ranges; pediatric dosing is weight-based. Always follow your clinician’s prescription. Orpha.net+1
Levetiracetam (antiepileptic; start ~500 mg twice daily in adults; titrate): Controls focal/generalized seizures; minimal interactions. Side effects: sleepiness, mood changes. Orpha.net
Valproate (antiepileptic; adults often 250–500 mg 2–3×/day; titrate to levels): Broad-spectrum seizure control; avoid in certain liver disorders; monitor platelets/liver enzymes. Side effects: weight gain, tremor. Orpha.net

Important: None of these medicines treat the underlying enzyme defect; they manage symptoms safely while research continues. Orpha.net+1
Dietary molecular supplements
Use only with clinician approval—doses vary by age, weight, drug interactions, and kidney/liver function. Evidence is supportive/adjunctive, not disease-curing.
Omega-3 (fish oil; e.g., 1–2 g/day EPA+DHA in adults): Anti-inflammatory; may ease neuropathic discomfort and support cardiovascular health.
Vitamin D3 (dose per level; often 800–2000 IU/day adults): Bone and immune support; corrects deficiency from low mobility/indoor time.
Magnesium (e.g., 200–400 mg/day): Muscle relaxation, helps constipation and sleep; avoid in kidney disease.
Coenzyme Q10 (e.g., 100–200 mg/day): Mitochondrial energy support; sometimes used for neuropathy fatigue.
Alpha-lipoic acid (e.g., 300–600 mg/day): Antioxidant; may reduce neuropathic pain symptoms.
B-complex (B1, B6, B12; doses per labs): Nerve support and anemia prevention; avoid excess B6.
L-carnitine (e.g., 500–1000 mg/day): Fatty-acid transport; sometimes used for fatigue/weakness.
Probiotics (per product): Gut microbiome support; reduce antibiotic-associated diarrhea/constipation.
Melatonin (1–5 mg at night): Sleep regulation; indirect seizure-trigger reduction.
Zinc (e.g., 10–25 mg/day short term): Immune function support if deficient; avoid chronic high doses.
(These choices align with supportive care principles for rare neuro-metabolic disorders; they do not replace medical therapy.) Orpha.net
Immunity booster / regenerative / stem-cell drugs
There are no approved “immunity-booster,” regenerative, stem-cell, or gene-editing drugs for alpha-NAGA deficiency at this time. Using unproven products can be risky. What is reasonable is to (1) keep routine vaccinations up to date and (2) join clinical-trial registries if eligible. Below are 6 scientifically discussed research directions (no dosing because none are approved):
Enzyme Replacement Therapy (ERT) concepts: Laboratory work has explored modified alpha-NAGA and other enzyme strategies; these remain investigational for NAGA deficiency. (Note: currently approved ERT exists for Fabry disease—not for NAGA deficiency.) PMC+1
Pharmacological chaperones: Small molecules that help misfolded lysosomal enzymes fold and reach lysosomes; explored broadly for lysosomal diseases, with early research interest in alpha-NAGA. PNAS
Gene therapy (AAV or lentiviral): Theoretical approach to deliver a correct NAGA gene to cells; not yet available clinically for this condition. Orpha.net
Hematopoietic stem-cell transplant (HSCT): Used in some other lysosomal diseases to supply donor enzyme from blood-borne cells; no established benefit for NAGA deficiency to date. Orpha.net
Substrate reduction strategies: Conceptually lowering production of storage substrates; no disease-specific therapy yet. Orpha.net
New delivery platforms (e.g., BBB-crossing enzymes, nanoparticles): Aimed at getting enzyme into the brain where symptoms are severe; still research-stage. Orpha.net
Surgeries / procedures
Gastrostomy tube (G-tube) placement: A feeding tube into the stomach for safe nutrition/hydration when swallowing is unsafe or weight is low; lowers aspiration risk. CheckOrphan
Tracheostomy (selected cases): For chronic airway protection or ventilation when cough is weak and aspiration is frequent. CheckOrphan
Orthopedic procedures (soft-tissue release, tendon lengthening, scoliosis surgery): To reduce painful contractures, improve sitting/positioning, or correct severe spine curves. CheckOrphan
Dermatologic laser surgery for angiokeratomas: To stop bleeding, relieve irritation, or improve appearance. MedlinePlus
Dental / oral procedures: Address tooth spacing/missing teeth, feeding, infection sources; reduce aspiration and pain. MedlinePlus
Prevention strategies
Genetic counseling for families; carrier and prenatal options. MedlinePlus
Early developmental screening and early-intervention referral. MedlinePlus
Vaccinations on schedule; flu/pneumococcal as advised. Genetic Diseases Center
Swallow safety: Texture-modified diets, supervised feeds to prevent aspiration. CheckOrphan
Seizure-action plan at home/school with rescue therapy. CheckOrphan
Contracture prevention with daily stretching and supported positioning. CheckOrphan
Skin care to avoid bleeding/infection of angiokeratomas. MedlinePlus
Infection control: Early treatment, chest physiotherapy if weak cough. CheckOrphan
Nutrition/hydration maintenance to prevent weight loss and dehydration triggers for seizures. Orpha.net
Care coordination with a rare-disease center so problems are anticipated, not reactive. Genetic Diseases Center
When to see a doctor
Immediately / emergency: New or prolonged seizure, breathing trouble, choking/aspiration, sudden severe weakness, fever with lethargy, new confusion, or uncontrolled bleeding from skin lesions. CheckOrphan
Soon (within days): Worsening swallowing, weight loss, persistent cough, recurrent vomiting, skin lesions that bleed, or increasing pain/numbness. CheckOrphan
Routine / scheduled: Regular visits with neurology, dermatology, audiology, physiotherapy/OT, nutrition, dentistry, and genetics; update vaccines; review rescue plans. Orpha.net
What to eat and what to avoid
Eat more of: Soft, easy-to-swallow foods if dysphagia is present (purees, yogurts, soups); nutrient-dense items (eggs, fish, beans, nut butters if safe), healthy fats (olive oil, avocado), fruits/vegetables well cooked, adequate fluids. Consider oral nutrition supplements if weight is low. Orpha.net
Limit/avoid: Dry, crumbly foods (risk of choking), very tough meats, alcohol (interacts with seizure medicines), highly processed salty snacks (worsen dehydration), and any food that worsens reflux. If on valproate or other meds, avoid new herbal products without approval due to interactions. CheckOrphan
General tips: Small, frequent meals; upright posture during and after meals; add fiber and fluids to prevent constipation; consider registered-dietitian support for individualized plans. CheckOrphan
Frequently asked questions (FAQ)
Is there a cure today? Not yet. Care focuses on symptom control and quality of life with a team approach. Research into enzyme/chaperone/gene strategies is ongoing. Orpha.net+1
How is the diagnosis made? Enzyme testing (alpha-NAGA activity) and genetic testing of the NAGA gene confirm the diagnosis. GGC+1
