African swine fever virus pE199L, as a mitophagy receptor, suppresses antiviral innate immunity to promote viral replication. (from Veterinary virology / ASFV vaccinology)
Xiaoxuan Li; Binbin Ren; Danyang Zhang; Miao Dan; Dongying Liu — Autophagy 2026
Score: 6/10 | Pathways: cGAS-STING, ISG15-mitophagy, ME-CFS, other

This paper directly addresses the cGAS-STING pathway and PINK1/Parkin-dependent mitophagy as targets of viral immune evasion—mechanisms central to the SAMHD1 A565T syndrome—demonstrating that mitophagic clearance of TBK1 suppresses type I interferon production, which is the inverse of the constitutive IFN-I overactivation and mitophagy block seen in this family, providing mechanistic insight into how mitophagy flux regulation gates cGAS-STING-IFN-I signaling amplitude.

B33-01 Cisd1 Regulates the Sting Pathway Through the Ubiquitin-proteasome System to Ameliorate COPD Progression (from Pulmonology/COPD)
J. Gao; Y. Song — American Journal of Respiratory and Critical Care Medicine 2026
Score: 6/10 | Pathways: cGAS-STING, JAK-STAT, other

This paper describes a mitochondria-to-STING innate immunity axis where CISD1 (a mitochondrial iron-sulfur protein) regulates STING degradation via K48-ubiquitination through Ubr5, directly engaging the cGAS-STING-TBK1-IRF3 pathway that is a core loop (BLUE) in the SAMHD1 haploinsufficiency mechanism, offering a novel STING regulatory checkpoint (ubiquitin-proteasome degradation) relevant to modulating the chronic interferon signature seen in the family, though SAMHD1 and dNTP biology are not addressed.

Score: 6/10 | Pathways: ME-CFS, JAK-STAT, POLG-mtDNA, cGAS-STING, NLRP3, ISG15-mitophagy, treatment-target, other

This review directly addresses ME/CFS molecular reclassification and identifies chronic innate immune activation, mitochondrial dysfunction, and genetic risk variants as core pathophysiology—all of which map onto the SAMHD1 A565T interferon-mitochondrial syndrome mechanism—but does not specifically implicate SAMHD1, cGAS-STING, or the dNTPase axis, making it a high-quality contextual reference for the proband's ME/CFS phenotype rather than a mechanistic confirmation.

K. D. Perera; E. Oltra; S. Carding — International Journal of Molecular Sciences 2026
Score: 5/10 | Pathways: ME-CFS, cGAS-STING, JAK-STAT, AGS-spectrum, other

The paper addresses ME/CFS pathogenesis through HERV-driven innate immune activation (including cGAS-STING sensing, LTR-driven interferon amplification, and JAK-STAT signaling) which overlaps mechanistically with the IFN-I loop central to SAMHD1 haploinsufficiency syndrome, and HERV reactivation is plausibly potentiated by the dNTP pool expansion that SAMHD1 normally suppresses (since SAMHD1 restricts retrotransposon/HERV reverse transcription), but the paper does not address SAMHD1, VDAC1, NLRP3, mitochondrial pathways, or ISG15-mitophagy directly.

Dual-targeting macrophage membrane nanosystem enhances radiotherapy-induced antitumor immunity via synergistic nuclear and mitochondrial DNA damage. (from Oncology/Nanomedicine)
Guangyu Ju; Qi Ding; Hongcang Gu; Rao Liu; Xiao Liu — Biomaterials science 2026
Score: 5/10 | Pathways: cGAS-STING, VDAC1, POLG-mtDNA, JAK-STAT, other

This paper demonstrates that mitochondrial membrane permeabilization (analogous to VDAC1 macropore opening in the BLUE stream) causes cytosolic accumulation of mitochondrial nucleic acids activating innate immune signaling and type I interferon, which mechanistically parallels the SAMHD1/VDAC1-mtDNA-cGAS-STING axis, but the context is engineered radiotherapy enhancement in glioma with no SAMHD1 involvement.

Terence Lee; Kiki Cham; Dong-Yan Jin — Cell Communication and Signaling : CCS 2026
Score: 4/10 | Pathways: cGAS-STING, other

MAVS organelle-specific signaling is upstream of IRF3/IFN-β activation (a convergent endpoint in the BLUE stream), but this paper addresses RNA sensing via RIG-I-like receptors rather than the cGAS-STING/VDAC1-mtDNA axis central to SAMHD1 haploinsufficiency, making the connection tangential despite sharing IRF3 and type I interferon as readouts.

Score: 4/10 | Pathways: POLG-mtDNA, ME-CFS, other

This paper reveals an interferon-independent mechanism by which RNA accumulation directly impairs mitochondrial membrane potential and respiration, which is tangentially relevant as the SAMHD1 haploinsufficiency model involves mitochondrial dysfunction, but the paper's core mechanism (excess RNA perturbing mitochondria during poxvirus infection) is not a primary pathway in the SAMHD1 A565T disease model and involves no direct overlap with cGAS-STING, VDAC1, ISG15, NLRP3, or dNTPase axes.

Score: 5/10 | Pathways: cGAS-STING, VDAC1, IRF7-metabolic, NLRP3, treatment-target, other

The paper directly demonstrates that mitochondrial injury drives mtDNA release activating cGAS-STING in macrophages (a core BLUE-stream pathway in the disease model), and documents hepatic steatosis/MASLD — a tracked family phenotype — but the mechanism is studied in a non-SAMHD1 context with no connection to dNTPase haploinsufficiency, making it an adjacent mechanistic parallel rather than a direct hit.

Mitochondrial OXPHOS restricts SARS-CoV-2 replication. (from virology/cell metabolism)
Soto Albrecht Yentli E; Morrow Ryan M; Kenney Devin; Olali Arnold Z; Wacquiez Al — 2026
Score: 5/10 | Pathways: POLG-mtDNA, ME-CFS, dNTPase, other

This paper demonstrates that mitochondrial OXPHOS suppresses SARS-CoV-2 replication via metabolic balance rather than innate immune differences, which is indirectly relevant because the SAMHD1 A565T haploinsufficiency causes mitochondrial dysfunction (via POLG stalling, perturbed dNTP pools, and OXPHOS impairment), potentially creating a permissive environment for enhanced SARS-CoV-2 replication and post-viral ME/CFS triggering in the proband, but the paper explicitly rules out innate immune pathway differences as the mechanism, limiting its direct relevance to the cGAS-STING/interferonopathy axis central to this disease.

Fan Yang; Rui Liu; Li Liu; Aijie Zhang; Bo Li — Frontiers in Immunology 2026
Score: 5/10 | Pathways: cGAS-STING, JAK-STAT, IRF7-metabolic, other

This review covers cGAS-STING, type I interferon, and innate immune evasion mechanisms directly relevant to the SAMHD1 interferonopathy framework, including metabolic reprogramming and ubiquitin-mediated regulation, but the lung cancer focus and lack of SAMHD1, NLRP3, VDAC1, or mitophagy content limits direct applicability to the disease profile.

The human cytomegalovirus vMIA protein inhibits apoptosis and innate immune signaling in human Mueller cells. (from ophthalmology/virology)
M. M. Sauter; H. Noel; Curtis R. Brandt — Experimental eye research 2026
Score: 5/10 | Pathways: cGAS-STING, VDAC1, ME-CFS, other

The paper demonstrates viral modulation of the cGAS-STING pathway and mitochondrial apoptosis signaling via vMIA, which intersects with core BLUE-stream mechanisms (cGAS-STING, mitochondrial morphology/MAVS, VDAC1-adjacent apoptosis) relevant to SAMHD1 interferonopathy, but the retinal/ocular context and viral immunoevasion framing are tangential to the family's haploinsufficiency syndrome.

Score: 5/10 | Pathways: JAK-STAT, AGS-spectrum, ME-CFS, cGAS-STING, clinical-phenotype, other

This paper demonstrates SARS-CoV-2 and RNA viral triggers driving dysregulated IFN-I/MDA5 signaling with myeloid ISG enrichment in pediatric autoimmune interferonopathy (JDM), which is mechanistically adjacent to the SAMHD1 haploinsufficiency model—particularly the viral trigger hypothesis (proband's adenovirus/SARS-CoV-2 onset), IFN-I loop amplification, and JAK-STAT pathway dysregulation—but does not address SAMHD1, cGAS-STING, VDAC1, mtDNA, or the specific dNTP-driven mechanism.

Score: 4/10 | Pathways: JAK-STAT, AGS-spectrum, clinical-phenotype, other

This paper documents clinical associations between IFN-I-driven systemic diseases and specific autoimmune dermatoses (LP, morphea, CS, GA), confirming that chronic type I interferonopathy states predispose to these skin conditions, which is peripherally relevant as downstream phenotypic consequences of the same JAK-STAT/IFN-I axis central to SAMHD1 haploinsufficiency, but provides no mechanistic insight into cGAS-STING, NLRP3, VDAC1, or SAMHD1-specific pathways.

Draidi Tamer; Khalil Mohammad; Kabaha Abed; Zuriqi Rafat; Masu'd Mohammad — 2026
Score: 4/10 | Pathways: AGS-spectrum, cGAS-STING, clinical-phenotype

This case documents ADAR-related AGS6, a type I interferonopathy sharing the AGS-spectrum with SAMHD1-related disease, but involves a different gene (ADAR), a distinct molecular mechanism (RNA editing failure rather than dNTPase/cGAS-STING), and the clinical novelty is the co-occurring TSHB mutation; the connection to SAMHD1 haploinsufficiency pathways is only via the broad interferonopathy/AGS diagnostic category.

Score: 3/10 | Pathways: NLRP3, clinical-phenotype, other

This paper investigates pyroptosis-related genes in endometriosis with some NLRP3/inflammasome relevance and touches on a gynecologic inflammatory condition, but the identified gene signatures (KIF13B, BAG6, MYO5A, HEATR2) have no direct connection to SAMHD1 pathways, cGAS-STING, or the core interferon-mitochondrial mechanism, making this only tangentially relevant via the shared pyroptosis/inflammasome biology and the family's endometrial carcinoma phenotype.

Yin Hongyan; Zhao Zhenchao; Wang Haiwei; Li Xin — 2026
Score: 3/10 | Pathways: cGAS-STING, NLRP3, other

While the paper involves cGAS-DNA phase separation and innate immune signaling (cGAS-STING pathway) relevant to the disease mechanism, the context is entirely viral (SVV 3C protease in porcine systems) and addresses antiviral peptide inhibition rather than constitutive interferonopathy or SAMHD1-related pathology, making the connection tangential at best.

Recent progress in cGAS-STING agonist design and mechanisms of cancer immune modulation. (from oncology/medicinal chemistry)
Wang Liao; Nafees Muhammad; Fei He; Hanif Muhammad; Yang Piaoping — 2026
Score: 4/10 | Pathways: cGAS-STING, treatment-target

This review covers cGAS-STING agonist design for cancer immunotherapy, touching the BLUE pathway's core signaling axis (cGAS→cGAMP→STING→IRF3→IFN-I), but focuses on activating rather than inhibiting this pathway and is oriented toward oncology rather than interferonopathy suppression, making it tangentially relevant at best—the therapeutic direction is opposite to what would benefit SAMHD1 haploinsufficiency patients.

Hyperglycaemia-induced metabolic stress and epigenetic imprinting in the inflammatory pathogenesis of diabetic neuropathy. (from Endocrinology/Neurology)
Faaz Bin Razi; Hamid Ashraf; S. Singhal; Ziaul Qamar; S. Moin — Diabetes research and clinical practice 2026
Score: 4/10 | Pathways: NLRP3, JAK-STAT, POLG-mtDNA, other

The paper discusses NLRP3 inflammasome activation, JAK/STAT signaling, and mitochondrial DNA as DAMPs in a hyperglycemia context, which are mechanistically relevant pathways in the SAMHD1 disease model, but the diabetic neuropathy framing and epigenetic focus are tangential to the core interferonopathy-mitochondrial syndrome without direct mechanistic overlap.

Antiaging Properties of the Klotho Protein (from Gerontology/nephrology)
G. J. Prud’homme; Qinghua Wang — Cells 2026
Score: 4/10 | Pathways: NLRP3, mTOR-lysosomal, other

Klotho's inhibition of NLRP3 inflammasome and NF-κB, mitochondrial ROS reduction, and autophagy modulation are tangentially relevant to the SAMHD1 interferonopathy-mitochondrial syndrome, but the paper does not address cGAS-STING, ISG15, VDAC1, or the dNTP pool mechanisms central to this disease, making the connection indirect background context only.

Mechanistic insights into atorvastatin-induced hepatotoxicity: molecular pathways, clinical relevance, and strategies for safer personalized therapy (from hepatology/pharmacology)
Mohammed A Abdel-Rasol; Wael M. El-Sayed — Clinical and Experimental Medicine 2026
Score: 4/10 | Pathways: NLRP3, VDAC1, mTOR-lysosomal, clinical-phenotype, other

The paper touches on NLRP3 inflammasome activation, mitochondrial dysfunction, and bile acid dysregulation in a hepatic context that is tangentially relevant to the family's hepatology phenotype (cholecystectomy clustering, hepatic steatosis) and the NLRP3/mitochondrial damage streams in the disease mechanism, but the focus is on drug-induced hepatotoxicity from atorvastatin rather than any intrinsic innate immune or SAMHD1-related pathway.

Neutrophil extracellular traps in atherothrombosis (from Cardiology/vascular biology)
Ming Xue; Xin Li; Songhai Li; Jing Yang — Chinese Bulletin of Life Sciences 2026
Score: 4/10 | Pathways: cGAS-STING, NLRP3, VDAC1, POLG-mtDNA, urate-NLRP3, other

The paper touches several core pathways (NLRP3 inflammasome, cGAS-STING via mtDNA release, mitochondrial dysfunction) as drivers of NETosis in atherosclerosis, which are mechanistically relevant to the SAMHD1 interferonopathy framework, but the primary subject is NETs in cardiovascular disease and there is no direct connection to SAMHD1, haploinsufficiency, or the specific family phenotype.

Regulated cell death: a multidimensional regulatory network in the pathogenesis of renal fibrosis. (from Nephrology)
Li Wen; Zhou Liang; Zhang Jinji; Sun Jingying; Feng Qing — 2026
Score: 3/10 | Pathways: NLRP3, mTOR-lysosomal, other

This review covers pyroptosis/NLRP3 and autophagy in renal fibrosis context, which are mechanistically relevant pathways in the disease model, but the organ focus (kidney fibrosis) and disease context (renal pathology) are not part of the family phenotype profile, making the connection largely tangential.
DOI: 10.1007/s10495-026-02358-3

ASS1 Promotes Atherosclerotic Inflammation Through the NLRP3/IL-33/ST2 Axis in Ox-LDL–Induced Foam Cells (from Cardiology/Vascular Biology)
Shaoyu Wu; Feihuang Han; Z. Qiao; S. Yuan; Xiaohui Bian — Frontiers in Bioscience-Landmark 2026
Score: 3/10 | Pathways: NLRP3, other

The paper examines NLRP3 inflammasome activation in foam cells via ASS1/STAT3/IL-33, which shares the NLRP3 node with the SAMHD1 disease mechanism, but the upstream driver (ox-LDL/argininosuccinate metabolism in atherosclerosis) is entirely distinct from the dGTP/urate/mtDNA-driven NLRP3 activation in SAMHD1 haploinsufficiency, with no mechanistic overlap in cGAS-STING, VDAC1, ISG15, or mitochondrial dNTP pathways.

Oxidative Stress and Inflammatory Pathways in Male Infertility: Molecular Mechanisms and Therapeutic Strategies (from andrology/reproductive medicine)
R. Zhankina; N. Tanideh; A. Botabayeva; U. Zhanbyrbekuly — West Kazakhstan Biomedicine Journal 2026
Score: 3/10 | Pathways: NLRP3, other

The paper discusses NLRP3 inflammasome activation and mitochondrial ROS in a reproductive context, which shares surface mechanistic overlap with the NLRP3 and mitochondrial dysfunction arms of the SAMHD1 pathomechanism, but the connection is entirely tangential — it does not address SAMHD1, cGAS-STING, interferonopathy, dNTP pool dysregulation, or any of the core molecular players, and male infertility is not a documented family phenotype.
DOI: 10.4103/wkbj.wkbj_17_26

Precision Neurodegeneration: Integrating Molecular Mechanisms, Biomarkers, and Targeted Therapeutics. (from Neurology/neurodegeneration)
Guizhen Lyu; Dongbing Li — CNS & neurological disorders drug targets 2026
Score: 3/10 | Pathways: NLRP3, ISG15-mitophagy, mTOR-lysosomal

While the paper mentions NLRP3 inflammasome and PINK1-Parkin mitophagy as therapeutic nodes in neurodegeneration, these are discussed in the generic context of Alzheimer's/Parkinson's disease without any mechanistic connection to SAMHD1, interferonopathy, cGAS-STING, or the dNTP pool dysregulation central to the disease profile.

The IFIT3 Protein of Porcine Induces Interferon Signaling and Inhibits the Early Gene Expression of African Swine Fever Virus (from veterinary virology)
Wen-Li Wang; Deng-Wu Han; Xing Yang; Xijuan Shi; Yesheng Shen — Viruses 2026
Score: 3/10 | Pathways: JAK-STAT, ISG15-mitophagy, other

This paper characterizes porcine IFIT3 (ISG60) as an antiviral ISG acting through STAT1/TBK1/IRF3 and JAK-STAT signaling, touching on ISG15 and IRF3 which are nodes in the disease mechanism, but the work is focused on ASFV restriction in swine macrophages with no direct relevance to SAMHD1, human interferonopathy, mitochondrial dysfunction, or the family's clinical phenotypes.
DOI: 10.3390/v18050566

Abstract C043: Novel insights into the immunoregulatory role of radiation activated club cells in non-small cell lung cancer (from Radiation oncology / lung cancer immunology)
Aakanksha R Kapoor; Arshdeep Singh; Bharati Swami; Yongfeng He; Vivek Mittal — Cancer Immunology Research 2026
Score: 3/10 | Pathways: JAK-STAT, ISG15-mitophagy, other

While the paper documents radiation-induced Type I interferon/ISG15/STAT1 upregulation in lung club cells — pathways central to the SAMHD1 interferonopathy mechanism — the context is entirely radiation-oncology/NSCLC tumor microenvironment with no connection to SAMHD1, dNTPase biology, mitochondrial dysfunction, or the family's clinical phenotype.
