On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
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.
