- Cogan's syndrome (CS) is a rare autoimmune disorder involving audio-vestibular and ocular inflammation. While systemic vasculitis is a known complication, its association with Moyamoya-type cerebrovascular remodeling has not been previously documented. A 19-year-old Asian woman was diagnosed with atypical CS following a presentation of hyperpyrexia, unintentional weight loss, and severe bilateral sensorineural hearing loss. After five years of appropriate immunosuppressive treatment, she developed subacute headaches, hypertension, and left hemiparesis and paresthesia. Despite normal inflammatory markers, neuroimaging revealed right-sided internal carotid artery occlusion and extensive collateralization characteristic of Moyamoya syndrome. Genetic testing showed a variant of uncertain significance in SLC37A4. The patient underwent a right extracranial-intracranial (STA-MCA) bypass, resulting in complete resolution of neurological symptoms. The late emergence of Moyamoya suggests that chronic autoimmune-mediated vascular injury may trigger progressive steno-occlusive disease. Clinicians should consider Moyamoya syndrome as a differential for new neurological symptoms in CS patients, even when systemic inflammation appears controlled. To our knowledge, this is the first reported case of concurrent Cogan's syndrome and Moyamoya vasculopathy at time of writing this article. - Source: PubMed

Phu AmyChao EricaSood RanjanaChen David RAgrawal Devendra K - The endoplasmic reticulum glucose-6-phosphatase (G6Pase) system, traditionally linked to hepatic and renal glucose homeostasis, is increasingly recognized as a regulator of intracellular glucose-6-phosphate (G6P) partitioning with broad relevance to cancer biology. Emerging evidence implicates its catalytic subunits (G6PC1-3) and associated transporters, particularly SLC37A4/G6PT, in redox control, calcium homeostasis, protein quality control, glycogen metabolism, autophagy, epithelial-mesenchymal transition, stemness, immune evasion, and therapy resistance. In several non-gluconeogenic cancers, elevated G6Pase-system activity is associated with aggressive phenotypes, whereas in liver and kidney, G6PC loss promotes metabolic disruption and dedifferentiation. This Review highlights how ER-directed G6P flux, rather than glucose production itself, may shape tumour behaviour and reveal context-specific therapeutic vulnerabilities. Importantly, the clinical targeting of this system remains at an early, largely preclinical stage, and the therapeutic opportunities discussed here should be regarded as hypotheses to be tested rather than established interventions. - Source: PubMed

Qi Lin KevinShen ChengHattori Motoyuki - Glucose 6 phosphate (G6P) homeostasis is essential for maintaining blood glucose levels and coordinating anabolic and catabolic pathways. A key step in this process is the delivery of G6P into the endoplasmic reticulum (ER), where it is hydrolyzed by glucose 6 phosphatase to glucose and inorganic phosphate (Pi). This transport step is carried out by the ER carrier SLC37A4 (also known as the G6P transporter, G6PT), which imports G6P into the ER lumen while exporting Pi to the cytosol, and loss-of-function mutations in SLC37A4 cause glycogen storage disease type Ib. Despite its central role in G6P homeostasis, how SLC37A4 recognizes G6P and couples its transport to Pi antiport has remained unclear. Here we report cryo-electron microscopy structures of human SLC37A4 in three states: the apo form at 2.8 Å resolution, a G6P-bound state at 3.2 Å resolution and a chlorogenic acid (CHA) bound state at 3.3 Å resolution. SLC37A4 adopts the canonical Major Facilitator Superfamily fold and harbors a central, positively charged cavity that accommodates anionic substrates. In the G6P-bound structure, SLC37A4 adopts an outward-open conformation facing the ER lumen, in which G6P binds to the electropositive pocket. In the CHA-bound structure, SLC37A4 adopts an inward-facing conformation, with CHA bound at a cytosolic site that locks the transporter in an arrested state and prevents the conformational transitions required for G6P/Pi exchange. Combined with thermostability and transport-based analyses of G6P binding and disease variants, these structures support a rocker switch mechanism in which electrostatic neutralization of the central positively charged cavity by anionic substrate drives the conformational changes underlying G6P/Pi exchange. Together, these findings define the structural basis of G6P/Pi exchange by SLC37A4, provide a molecular rationale for pathogenic mutations in glycogen storage disease type Ib, and provide a framework for targeting SLC37A4 to modulate G6P homeostasis. - Source: PubMed

Li HuiPeng XiaominHuang YuwenWu WenchengLi NanCheng ZiqiWei Xuepeng - Genotype-first screening compares patient genomes to a standard reference. The GRCh38 linear assembly contains reference minor alleles (RMAs), posing a critical structural vulnerability for automated clinical variant classification. To determine whether RMAs systematically generate false-positive annotations, we conducted an observational case series of 20 healthy adults undergoing preventive genome sequencing. Automated bioinformatic processing was performed using the GRCh38 linear reference to identify "high-impact" variant annotations generated at loci where GRCh38 differs from the population consensus major allele. Among all 20 participants (100%), linear alignment to GRCh38 systematically misclassified functional major alleles as false-positive "high-impact" annotations at three distinct loci (SLC37A4, CIMIP2A, and GPR33). These artifacts occurred solely because analysis software mathematically defined the healthy wild-type state as a deviation from the rare RMA. Cross-referencing with gnomAD confirmed these as population-dominant benign alleles. Furthermore, this inherent reference bias introduces a theoretical risk of false-negative classifications if RMAs mathematically mask true pathogenic variants. Automated pipelines using linear references systematically misclassify healthy alleles as high-impact functional annotations. While downstream population-frequency filters manage false-positive artifacts, this retrospective patching creates an unsustainable bottleneck for population-scale screening. Transitioning to graph-based pangenome references represents a highly promising approach to directly resolve these diagnostic vulnerabilities at the alignment level, though computational and standardization challenges must first be addressed to ensure the accuracy of large-scale aging research. - Source: PubMed
