Mpox virus pangenomics reveals determinants of subclade Ib
Bibliographic record
Abstract
ABSTRACT Mpox, formerly monkeypox, is a viral zoonotic disease caused by the mpox virus (MPXV). MPXV, which is phylogenetically divided into Clades I and II, was declared a Public Health Emergency of International Concern for the second time in August 2024 due to rapid geographic expansion of Clade I viruses including the newly identified subclade Ib. With a unique set of genomic mutations and sustained human-to-human transmission, subclade Ib has rapidly spread throughout the eastern Democratic Republic of the Congo as well as neighboring non-endemic regions and outside the African continent. Currently, there is a lack of comparative genomic data with which to address the potential zoonotic transmissibility and pathobiology of subclade Ib. Here we report 105 protein-coding genes that are shared by all the queried MPXV subclade Ia, Ib, and IIb genomes. Our comparative genomic analysis identified that the core Clade I gene pair, OPG032 and OPG033 , is now a critical branching element for subclade Ia/Ib due to their loss in subclade Ib. These genes encode the complement control protein (a vaccinia virus ortholog associated with virulence), and a Kelch-like protein associated with pathogenesis, respectively, suggesting a functional evolution that might play an important role in the pathobiology of the new MPXV subclade Ib. Our results lay the groundwork to exploit the genomic elements of MPXV as potential targets for therapeutics development/repurposing, vaccine design, and molecular diagnostic expansion, as well as to uncover the viral diversity, and human-to-human transmission of MPXV.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
