Autosomal recessive severe congenital neutropenia due to JAGN1 deficiency is a rare, inherited immune disorder. Babies are born with very low numbers of neutrophils (a type of white blood cell that fights bacteria and fungi). The problem comes from harmful changes in the JAGN1 gene. This gene helps white blood cells mature and survive inside the cell’s “factory,” the endoplasmic reticulum (ER). When JAGN1 does not work, neutrophils fail to develop, die too early, and cannot make normal granules. The result is repeated, serious infections starting in early life. Some people respond poorly to standard G-CSF shots, and some need stem-cell (bone-marrow) transplant. Frontiers+2PMC+2
JAGN1-deficiency SCN is a very rare, inherited immune disorder. Babies are born with extremely low neutrophils (infection-fighting white blood cells), leading to frequent and serious bacterial or fungal infections. The JAGN1 gene helps young neutrophils fold and ship proteins inside the cell’s endoplasmic reticulum (ER). When JAGN1 is faulty (two harmful copies, one from each parent), neutrophils don’t mature or survive well, and some patients also have broader immune problems (like antibody issues). Because the neutrophil shortage is chronic, children need lifelong infection-prevention plus medicines that raise neutrophils or, in some cases, a stem-cell transplant. PubMed+2PMC+2
Studies show JAGN1 mutations disrupt ER-stress handling, protein glycosylation/trafficking, and signaling downstream of the G-CSF receptor, so myeloid precursors (neutrophil “teenagers”) die early. Lab and animal models support this mechanism, and case series describe severe, early-onset infections, sometimes poor responses to standard growth-factor therapy. PubMed+2PMC+2
Other names
This condition is also called: JAGN1-associated severe congenital neutropenia, SCN due to JAGN1, autosomal recessive SCN6, or severe congenital neutropenia type 6 (SCN6). These labels all point to the same disease mechanism—biallelic (both-copy) variants in JAGN1 leading to very low neutrophils and early, severe infections. PMC+2PubMed+2
Types
Doctors do not split this disease into clinical “subtypes” the way they do for some other disorders. Instead, they describe it by genetic and functional categories:
By variant class: missense, nonsense, frameshift, or splice variants in JAGN1. Different changes can produce different severities but the core problem is the same—poor neutrophil development and survival. PubMed+1
By treatment response: some patients are poor responders to G-CSF (the usual drug that boosts neutrophils). A subset may improve with GM-CSF or require hematopoietic stem-cell transplantation (HSCT). PMC+2Frontiers+2
By extra-hematologic features: several reports describe facial differences, oral/skin ulcers, growth issues, and occasionally other anomalies; the range is broad, and some patients have few or none of these. BioMed Central+1
Causes
Below are the disease causes in simple language. Each “cause” explains a piece of why neutropenia and infections occur in JAGN1 deficiency.
Biallelic JAGN1 gene variants. Both copies of JAGN1 carry harmful changes (autosomal recessive). This is the root cause. PubMed
ER (endoplasmic reticulum) stress. Faulty JAGN1 disrupts the ER, leading to protein-handling stress inside neutrophil precursors. Stressed cells die earlier. Wiley Online Library
Defective secretory pathway. JAGN1 normally helps with early secretory trafficking; loss impairs granule formation in developing neutrophils. Frontiers
Abnormal neutrophil granules. Without proper granules, neutrophils cannot store or release enzymes that kill microbes. PMC
Increased apoptosis of precursors. Calcium–calpain pathways activate cell death in the bone marrow, reducing mature neutrophils. Wiley Online Library
Impaired G-CSF signaling. The G-CSF receptor pathway is disrupted, so standard G-CSF often works poorly. PMC
Abnormal protein glycosylation. Glycosylation of immune proteins, including on neutrophils (and even IgG in B-cells), is disturbed; this weakens immune functions. PMC+1
Reduced neutrophil survival in blood and tissues. Even the few neutrophils produced may die sooner. PMC
Poor migration/chemotaxis. Abnormal trafficking machinery can blunt migration to infection sites. maayanlab.cloud
Weak antifungal responses. Defects blunt the response to organisms like Candida, raising invasive fungal risk. maayanlab.cloud
Bone-marrow maturation arrest. Cells stall at promyelocyte/myelocyte stages, so mature neutrophils are scarce. ScienceDirect
Secondary bacterial colonization. Mucosa (mouth, skin, gut) more easily colonized and infected because neutrophil defense is low. Orpha
Recurrent inflammation–tissue damage cycle. Repeated infections damage tissues, inviting further infections. Orpha
Oral mucosal fragility and ulcers. Mouth ulcers provide entry points for bacteria and fungi. MDPI
Skin barrier breaches. Folliculitis, abscesses, and wounds occur more often with neutropenia. BioMed Central
Sinopulmonary vulnerability. Nose, sinus, and lung infections are common because first-line neutrophil defense is weak. BioMed Central
Limited vaccine responses in some patients. Glycosylation and immune-cell dysfunction can dampen humoral responses (context from JAGN1’s role in B cells). PMC
Poor response to standard doses of G-CSF. This prolongs periods of severe neutropenia. PMC
Delayed diagnosis. Rare disease status can delay correct treatment, allowing infections to accumulate. Frontiers
Genotype–phenotype variability. Some variants are especially damaging, leading to more severe neutropenia and complications. PMC
Common symptoms and signs
Frequent, severe bacterial infections in early infancy—pneumonia, sepsis, skin abscesses, ear and sinus infections. Low neutrophils make it hard to control bacteria. Orpha+1
Mouth ulcers and gum infections (gingivitis, periodontitis). Neutrophils normally protect the mouth; without them, sores persist. MDPI
Skin infections and boils. Cuts and folliculitis progress to abscesses more easily. BioMed Central
Fevers that come back often. Fever is a warning sign of serious infection in neutropenia. Orpha
Lung infections (pneumonia). Cough, fast breathing, or chest pain can signal deep infections. BioMed Central
Blood infections (sepsis). With very low neutrophils, bacteria can spread into the blood and cause shock. Frontiers
Fungal infections (like Candida). Antifungal defense can be weak due to neutrophil and glycosylation defects. maayanlab.cloud
Ear infections (otitis) and sinusitis that keep returning. BioMed Central
Slow weight gain or growth concerns in some children, due to repeated illness. BioMed Central
Mouth pain, trouble eating because of ulcers and gum disease. MDPI
Fatigue and low energy during infections or after frequent antibiotics/hospitalizations. Orpha
Swollen lymph nodes during infections. Orpha
Facial differences in some cases (e.g., triangular face, prominent ears) but not always present. turkjpediatr.org
Aphthous ulcers/skin aphthosis reported in cohorts of JAGN1 patients. ScienceDirect
Poor response to routine G-CSF (clinical clue when infections persist despite therapy). PMC
Diagnostic tests
A) Physical examination
Full infectious check. The doctor looks for fever, fast breathing, low blood pressure, and signs of sepsis because neutropenia hides classic pus formation. ScienceDirect
Mouth and gum exam. Ulcers, gingivitis, or oral thrush suggest neutrophil failure at the mucosa. MDPI
Skin exam. Boils, abscesses, or non-healing wounds point to severe neutropenia. BioMed Central
Ear–nose–throat and lung exam. Persistent otitis, sinus tenderness, or chest crackles hint at recurrent bacterial disease. BioMed Central
Growth and development review. Repeated infections can affect growth; some reports note facial differences. turkjpediatr.org
B) “Manual” or bedside/in-lab clinician tests
Manual differential on a blood smear. A technologist visually counts white cells and looks for immature forms, toxic granulation, or maturation arrest clues. ScienceDirect
Absolute neutrophil count (ANC) calculation. ANC = WBC × (% neutrophils + % bands). In SCN, ANC is usually very low. ScienceDirect
Serial temperature and sepsis screening. Repeated vitals, perfusion checks, and sepsis scores help catch deterioration early in neutropenic patients. ScienceDirect
Wound/ulcer swab for culture. Simple bedside sampling helps target antibiotics to the right germs. ScienceDirect
Oral assessment tools. Structured checks for mucositis/ulcers guide dental and antimicrobial care. MDPI
C) Laboratory & pathological tests
Complete blood count (CBC) with differential. Confirms neutropenia; anemia or thrombocytopenia may also be assessed. ScienceDirect
Inflammatory markers (CRP/procalcitonin). Help detect bacterial infections early when exam is subtle. ScienceDirect
Blood cultures (and site-specific cultures). Identify bacteria or fungi during fever spikes. ScienceDirect
Bone-marrow aspirate/biopsy. Shows myeloid maturation arrest and rules out other marrow diseases. ScienceDirect
Genetic testing (targeted panel or exome) for JAGN1. Confirms biallelic pathogenic variants; essential for exact diagnosis and family counseling. PMC
Flow cytometry / functional assays. Can examine myeloid precursors and surface receptors (e.g., G-CSF receptor pathway context). PMC
Glycosylation/immune work-up as indicated. Because JAGN1 can affect glycosylation and humoral immunity (e.g., IgG N-glycans). PMC+1
D) Electro-diagnostic and monitoring tests
Pulse oximetry/ECG monitoring during sepsis care. Neutropenic sepsis needs tight monitoring to detect shock or hypoxia quickly. ScienceDirect
Hearing screening (when clinically indicated). Some inborn errors of immunity cohorts report hearing issues; screening is prudent if there are concerns. RUPress
EEG only if neurological symptoms occur. Not routine, but infections or metabolic stress can rarely cause seizures—EEG helps if events happen. ScienceDirect
E) Imaging tests
Chest X-ray. Looks for pneumonia or lung abscess in febrile neutropenia. ScienceDirect
Chest/abdominal CT (if severe infections). Defines deep abscesses or invasive fungal disease. ScienceDirect
Ultrasound of liver/spleen or soft tissue. Finds collections that need drainage and checks organ size. ScienceDirect
Dental panoramic X-ray (as needed). Recurrent oral infections may damage teeth and bone; imaging helps plan care. MDPI
Sinus imaging (if chronic sinusitis). Helps ENT plan surgery or prolonged therapy. BioMed Central
