Article Abstract

Von Hippel Lindau(VHL)syndrome presents with cerebellar and spinal hemangioblastomas, renal cell cancer, neuroendocrine pancreatic tumor, and pheochromocytoma and it is caused by germline mutations in the gene. Pathogenic germline variants in the succinate dehydrogenase A () gene are associated with paraganglioma and pheochromocytoma. Here we report co-occurrence of germline pathogenic variants in both and genes in a patient who presented with pancreatic neuroendocrine tumor. As these genes converge on the pseudo-hypoxia signaling pathway, further studies are warranted to determine the significance of co-occurrence of these variants in relation to tumor penetrance, disease severity, treatment response and clinical outcomes in this selected group of patients.

Pathogenic variants in the gene COQ4 cause primary coenzyme Q deficiency, which is associated with symptoms ranging from early epileptic encephalopathy up to adult-onset ataxia-spasticity spectrum disease. We genetically modified commercially available wild-type iPS cells by using a CRISPR/Cas9 approach to create heterozygous and homozygous isogenic cell lines carrying the disease-causing COQ4 variants c.458C > T, p.

Purpose: To assess modified folinic acid/leucovorin, fluorouracil, irinotecan, oxaliplatin (FOLFIRINOX; mFFX) versus gemcitabine/nab-paclitaxel (GnP) in de novo metastatic pancreatic ductal adenocarcinoma (PDAC) and explore predictive biomarkers.

Patients And Methods: Patients were randomly assigned 1:1 to mFFX or GnP with exclusion of germline pathogenic variants in or . The primary end point was progression-free survival (PFS) between arms with 0.

Germline Findings From Tumor-Only Comprehensive Genomic Profiling in the RATIONAL Study: A Missed Opportunity?

JCO Precis Oncol

September 2025

Cell Biology and Biotherapy Unit, Istituto Nazionale Tumori IRCCS Fondazione G. Pascale, Napoli, Italy.

Purpose: Tumor comprehensive genomic profiling (CGP) may detect potential germline pathogenic/likely pathogenic (P/LP) alterations as secondary findings. We analyzed the frequency of potentially germline variants and large rearrangements (LRs) in the RATIONAL study, an Italian multicenter, observational clinical trial that collects next-generation sequencing-based tumor profiling data, and evaluated how these findings were managed by the enrolling centers.

Patients And Methods: Patients prospectively enrolled in the pathway-B of the RATIONAL study and undergoing CGP with the FoundationOne CDx assays were included in the analysis.

Frequent emergence of respiratory viruses with pandemic potential, like SARS-CoV-2 or influenza, underscores the need for broad-spectrum prophylaxis. Existing vaccines show reduced efficacy against newly emerged variants, and the ongoing risk of new outbreaks highlights the importance of alternative strategies to prevent infection and viral transmission. As respiratory viruses primarily enter through the nose, formulations targeting the nasal epithelium are attractive candidates to neutralize pathogens and thus prevent or minimize infection.

Influenza A viruses remain a global health threat, yet no universal antibody therapy exists. Clinical programs have centered on neutralizing mAbs, only to be thwarted by strain specificity and rapid viral escape. We instead engineered three non-neutralizing IgG2a mAbs that target distinct, overlapping epitopes within the conserved N terminus of the M2 ectodomain (M2e).
