Autosomal Systemic Lupus Erythematosus Type 16

Autosomal systemic lupus erythematosus type 16 is a rare, inherited kind of lupus. Doctors often shorten the name to SLEB16. It happens when a person is born with harmful changes (mutations) in a gene called DNASE1L3. This gene makes an enzyme that cuts up extra DNA outside cells. When the enzyme does not work, bits of DNA stay in the blood. The immune system can mistake this DNA for a threat. The body then makes antibodies against its own tissues. This starts ongoing inflammation that can harm the skin, joints, kidneys, blood cells, nerves, and other organs. Because the faulty gene is on a non-sex chromosome and you need two faulty copies to get sick, doctors call it autosomal recessive. It often starts in childhood and may come with kidney disease (lupus nephritis) and certain autoantibodies. MalaCards+3NCBI+3NCBI+3

ASLE16 is a rare, inherited form of lupus caused by harmful changes in the DNASE1L3 gene. This gene makes an enzyme that clears leftover DNA debris in the bloodstream. When the enzyme is missing or weak, DNA fragments build up and the immune system mistakes them for danger, creating anti-DNA autoantibodies, inflammation, and multi-organ lupus. ASLE16 is autosomal recessive (you inherit two faulty copies), and it often starts in childhood or adolescence. Clinically it looks like SLE—rashes, arthritis, low blood counts, kidney and vessel inflammation—but the genetic cause is distinct. FDA Access Data+3FDA Access Data+3FDA Access Data+3

Lupus is an autoimmune disease—your immune system attacks your own tissues. In ASLE16, a built-in cleanup tool (DNase1L3) fails. Dead cells shed DNA into the blood every day. Normally DNase1L3 chops this DNA into tiny harmless pieces. Without that, larger DNA pieces float around and trigger alarms. The body then creates antibodies against DNA (anti-dsDNA) and other cell parts. These immune complexes lodge in skin, joints, kidneys, and vessels and light the “interferon pathway,” causing flares. Because the root problem is genetic, ASLE16 can be severe and can start early, but it is managed with the same principles as SLE—sun protection, vaccines, antimalarials like hydroxychloroquine, and organ-protective immunosuppression for flares (especially kidney disease).

Other names

People and databases may use different names for the same condition:

• SLEB16

• Systemic lupus erythematosus 16

• Autosomal SLE or familial SLE (meaning it runs in families)

• DNASE1L3-related lupus (links the disease to the gene involved) National Organization for Rare Disorders+1

Types

Doctors do not split SLEB16 into official “types,” but it helps to group by how and where it shows up. These patterns can overlap:

1. Kidney-dominant SLEB16. Kidney swelling and scarring (lupus nephritis) lead to protein in urine, swelling of legs, and high blood pressure. This pattern is common in inherited lupus. MalaCards

2. Skin- and joint-dominant SLEB16. Rashes, mouth sores, hair loss, and painful, stiff joints can be the main problems. MedlinePlus+1

3. Blood-dominant SLEB16. Low red cells, white cells, or platelets happen because the immune system attacks blood cells. MedlinePlus

4. Nervous-system SLEB16. Headaches, seizures, mood changes, or numbness/weakness show brain or nerve involvement. Medscape

5. Vasculitic SLEB16. Inflammation of blood vessels can cause tender purple spots on the skin, nerve pain, or organ damage; ANCA antibodies may be more frequent in this inherited form. MalaCards

---

Causes

1. DNASE1L3 loss-of-function mutations. Two faulty copies mean the enzyme cannot clear extra DNA. The immune system reacts to this DNA and turns against the body. This is the root cause of SLEB16. NCBI+1

2. Autosomal recessive inheritance. The disease happens when both parents carry one faulty copy and a child inherits both. Family history and consanguinity can raise the chance. NCBI

3. Accumulation of extracellular DNA. Uncleared DNA in the bloodstream activates immune sensors and drives autoantibody production. Nature

4. Immune complex formation. Antibodies bind to DNA and form complexes that deposit in organs (such as kidneys) and cause inflammation. New England Journal of Medicine

5. Type I interferon pathway over-activation. DNA sensing boosts interferon signals that keep the immune system “on.” This worsens lupus activity. Nature

6. Complement system activation. Immune complexes activate complement, which attracts inflammatory cells and injures tissues. New England Journal of Medicine

7. Childhood onset biology. Earlier onset often means stronger genetic drivers, so symptoms may be more severe or organ-focused. MalaCards

8. Ultraviolet (UV) light. UV damages skin cells and releases DNA, feeding the cycle of autoimmunity and flares. Medscape

9. Viral infections. Some infections increase immune activation and expose nuclear material, which may trigger flares in genetically predisposed people. New England Journal of Medicine

10. Bacterial infections. Bacterial products can stimulate immune pathways and worsen inflammation. New England Journal of Medicine

11. Female hormones. Estrogen can heighten immune responses; many lupus cases occur in females, even in genetic subtypes. Nature

12. Epigenetic changes. Chemical changes to DNA and histones shift immune cell behavior and may amplify disease. New England Journal of Medicine

13. Gut microbiome imbalance. Changes in gut bacteria can influence the immune system and inflammation. Nature

14. Cigarette smoke or silica exposure. Environmental irritants can trigger immune activation and flares. New England Journal of Medicine

15. Certain medicines (lupus-like reactions). Some drugs can cause lupus-like symptoms; in genetic lupus, they may also trigger flares. Medscape

16. Psychological stress. Stress hormones and poor sleep can raise inflammatory signals and worsen symptoms. Nature

17. Low vitamin D and low sunlight tolerance. Vitamin D helps regulate immunity; low levels are linked to stronger disease activity. Medscape

18. Pregnancy/post-partum hormonal shifts. Hormone changes and immune adjustments around pregnancy can affect flares. Medscape

19. Obesity and metabolic stress. Extra adipose tissue releases inflammatory mediators that may add to disease activity. Nature

20. Delayed clearance of dying cells. Inherited problems clearing cell debris (like in SLEB16) keep feeding the immune system with self-antigens. Nature

Symptoms

1. Tiredness and low energy. Ongoing inflammation makes people feel worn out, even after rest. Medscape

2. Fever or feeling hot. The immune system releases signals that raise body temperature. Medscape

3. Joint pain and stiffness. The lining of joints gets inflamed, so hands, wrists, knees, and ankles may ache or swell. Medscape

4. Skin rashes. A butterfly-shaped rash on the cheeks or other photosensitive rashes can appear after sun exposure. MedlinePlus

5. Mouth or nose sores. Small, painless ulcers can show up during flares. Medscape

6. Hair loss (shedding). Inflammation around hair follicles can cause thinning or patches of hair loss. Medscape

7. Swelling of legs or puffy eyes. Kidney disease leads to protein loss and fluid buildup. MalaCards

8. Foamy or bloody urine. Protein or blood in urine is a sign of kidney inflammation. Medscape

9. Chest pain or shortness of breath. Inflammation around the heart or lungs (serositis) can make breathing painful. Medscape

10. Headaches or seizures. The brain can be involved; some children with inherited forms have nervous system symptoms. Medscape

11. Numbness or weakness. Inflamed nerves or small vessels can cause neuropathy or weakness. Medscape

12. Easy bruising or nosebleeds. Low platelets raise bleeding risk. MedlinePlus

13. Frequent infections. Some immune changes and medicines used later can increase infection risk; disease activity itself can also play a role. Medscape

14. Raynaud phenomenon. Fingers or toes turn white or blue in cold due to vessel spasm. Medscape

15. Weight loss and poor appetite. Chronic inflammation and active disease reduce appetite and weight. Medscape

Diagnostic tests

(I’ll group them as the examiner would: physical exam, manual/bedside checks, lab/pathology, electrodiagnostic tests, and imaging. Your doctor chooses tests based on symptoms.)

A) Physical exam

1. Full skin and joint exam. The doctor looks for rashes, hair loss, mouth sores, and swollen or tender joints that suggest active lupus. Medscape

2. Blood pressure and edema check. High blood pressure and ankle or eyelid swelling point to kidney involvement. Medscape

3. Heart–lung exam. A stethoscope may pick up friction rubs from inflamed heart or lung linings, or fluid sounds. Medscape

4. Neurologic exam. Reflexes, strength, sensation, and coordination help detect brain or nerve disease. Medscape

B) Manual/bedside tests

5. Bedside urine dipstick. A simple strip test checks for protein and blood in urine, which can flag lupus nephritis and prompt full lab testing. Medscape

6. Orthostatic vitals. Measuring pulse and pressure lying and standing may uncover dehydration or autonomic issues during flares. Medscape

7. Pitting edema assessment. Pressing on the shin or ankle helps confirm fluid retention from kidney disease. Medscape

C) Laboratory and pathological tests

8. Complete blood count (CBC). Looks for anemia, low platelets, or low white cells, which are common in lupus. Medscape

11. Anti-double-stranded DNA (anti-dsDNA). More specific for lupus; often tracks kidney disease activity. MedlinePlus

12. Extractable nuclear antigen panel (anti-Sm, anti-RNP, etc.). Anti-Sm supports the diagnosis; other antibodies guide care. Medscape

13. Complement levels (C3, C4). Low levels suggest active immune-complex disease, especially in lupus nephritis. Medscape

14. Urinalysis and urine protein-to-creatinine ratio. Quantifies kidney injury and protein loss. Medscape

15. Kidney biopsy (pathology). A tiny tissue sample shows the class of lupus nephritis and guides treatment decisions. This is often key in kidney-dominant SLEB16. Medscape

D) Electrodiagnostic tests

16. Electroencephalogram (EEG). Records brain waves to evaluate seizures or altered awareness in neuro-lupus. Medscape

17. Nerve conduction studies/electromyography (NCS/EMG). Tests nerve and muscle function if there is numbness, tingling, or weakness. Medscape

E) Imaging tests

18. Kidney ultrasound. Shows kidney size and rule-out structural problems; complements lab tests and biopsy. Medscape

19. Chest X-ray or echocardiogram. Looks for fluid around the lungs or heart and checks heart function. Medscape

20. Brain MRI. Evaluates headaches, seizures, or focal neurologic symptoms when neuro-lupus is suspected. Medscape

When to see a doctor (or urgent care)

Call your lupus team urgently for new swelling (legs/face), foamy or bloody urine, suddenly rising blood pressure, severe chest pain or shortness of breath, high fever without clear cause, rapidly worsening rash, severe headaches, seizures, or sudden weakness/numbness. These can signal kidney flares, serositis, infection, or neuro-lupus that need fast care. Even mild flares (more fatigue, joint swelling, mouth ulcers, low-grade fevers) deserve early attention to adjust treatment before damage occurs. Routine urine and blood tests—even when you feel fine—are important because some kidney flares start silently. NIAMS+3Lupus Foundation of America+3Mayo Clinic+3

FAQs

1) Is ASLE16 different from “regular” lupus?
Yes. The symptoms overlap, but ASLE16 has a known genetic cause (DNASE1L3). Treatment follows general SLE care, with extra attention to early-onset and family genetics. FDA Access Data+1

2) Can lifestyle changes really help?
Yes—sun protection, no smoking, exercise, bone health, vaccines, and kidney checks all reduce flares and damage over time. lupus.pt+1

3) Is hydroxychloroquine necessary?
It’s the foundation drug for most people with lupus unless contraindicated; it prevents flares and is kidney-friendly. Keep annual eye exams. Annals of the Rheumatic Diseases

4) What if my kidneys are involved?
Guidelines endorse combination therapy (e.g., mycophenolate + belimumab or CNI) with careful steroid minimization and kidney-protective measures. Rheumatology Advisor+1

5) Are biologics safe?
Belimumab and anifrolumab are FDA-approved for SLE; infections are the main risk—your team will screen and time vaccines. FDA Access Data+1

6) Can supplements cure lupus?
No. Some (vitamin D, omega-3) may support control, but they do not replace medicines. Always check for interactions. PMC+1

7) Can pregnancy be safe?
Yes—with planning in remission, continuing HCQ, and coordinated care. lupus.pt

8) Will steroids hurt me long term?
They work fast but can harm bones, sugar, and weight. The plan is lowest dose for shortest time and early switch to steroid-sparing drugs. lupus.pt

9) Is plasmapheresis a cure?
No—it’s a bridge in select crises; benefits are temporary and used with other treatments. ammtac.org

10) When do I need a kidney biopsy?
Often when protein in urine is ≥0.5 g/g or kidney function worsens without another cause. American College of Rheumatology

11) Do all lupus diets ban nightshades/meat?
No. There’s no single lupus diet. Focus on a balanced, heart- and kidney-friendly pattern; personalize with your clinician. Lupus Foundation of America

12) What about SGLT2 inhibitors or statins?
They’re not lupus drugs but may be used to manage CKD or cardiovascular risk as part of holistic care. KDIGO

13) Can HSCT “reset” my immune system?
In selected severe cases at expert centers, A-HSCT can induce long remissions—but risks are substantial; it’s not routine. Nature

14) Is rituximab approved for SLE?
No—off-label only for refractory disease; benefits exist in some cases, risks include infusion reactions and infections. FDA Access Data

15) How often should I screen for kidney trouble?
At least every 6–12 months in SLE, and more often during flares. A simple urine protein check can save kidneys. American College of Rheumatology
