Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Meiotic recombination commences with hundreds of programmed DNA breaks, however the degree to which they are accurately repaired remains poorly understood. We report that meiotic recombination is 8-fold more mutagenic for single-base substitutions than was previously understood, leading to de novo mutation in 1 in 4 human sperm and 1 in 12 human eggs. Its impact on indels and structural variants is even higher, with 100-1400-fold increases in rates per break. We uncover novel mutational signatures and footprints relative to break sites, which implicate error-prone mechanisms including translesion synthesis and end-joining repair pathways in meiotic break repair. These mechanisms drive mutagenesis in human germlines and lead to disruption of hundreds of genes genome-wide.
