COSMIC SBS5 - Mutational Signatures

WebUsing mutations from 10,250 cancer genomes across 36 cancer types, we investigated clock-like mutational processes that have been operating in normal human cells. Two mutational signatures show clock-like properties. Both exhibit different mutation rates in different tissues. WebThe mutations attributed to SBS5 increase steadily as we age; moreover, there is considerable variability in the extent of this “clock-like” effect between individuals (Alexandrov et al. 2015). SBS5 accounts for >70% of mutations in early human embryos (Ju et al. 2024) and ∼75% of de novo mutations in human children (Rahbari et al. 2016).
