Table 2.

Burdens and activities of single-base substitution (SBS) mutations of different types, including SBS signatures, in dMutLα and dMutSα CRCs. Median (IQR) is shown. P from a Wilcoxon test. Other Signatures include SBS7c, SBS14, SBS17a, SBS17b, SBS18, SBS20, SBS36, SBS41, SBS93, and mutations not assigned to any pre-existing COSMIC mutation signature
