Skin mutant clones
A comparison between individuals from the UK and Singapore suggests that the difference in skin cancer incidence is due to distinct mutational spectra and patterns of selection.

DNA mismatch repair deficiency (MMRd) is associated with elevated tumor mutational burden (TMB) and exceptional immunotherapy responses, yet some patients experience no clinical benefit. Recent work proposes that high intra-tumoral heterogeneity can offset immunogenicity in sporadic MMRd, suggesting a potential mechanism of immunotherapy failure.
