Transcription start sites experience a high influx of heritable variants fuelled by early development
Mutations drive evolution and genetic diversity, but the impact of transcription on germline mutagenesis remains poorly understood. Here, we identify a hypermutation phenomenon at transcription start ...

Did you know that transcription start sites harbor a huge excess of germline variants? Turns out this is driven by (divergent) transcription, mitotic, but not meiotic(!), double-strand breaks and early mosaic variants. Read the full story here: www.biorxiv.org/content/10.1...

Very happy to announce our paper on mutational signatures caused by mismatch repair knockouts. We find SBS57 is driven by alignment errors in MMR-deficient cells, experimentally confirm the association of MMR with SBS1 & expose differences between in vitro and in vivo MMR loss: tinyurl.com/ycyprxme
Dissecting DNA-mismatch-repair-driven mutational processes in human cells
Mismatch repair (MMR) is a crucial DNA repair pathway that maintains genomic integrity by correcting replication errors and various forms of DNA damage. MMR deficiency (MMRd) leads to increased mutati...
