APC and skin basal cell carcinoma: We found that compared to non-lesional tissue, the DNA repair genes were more markedly overexpressed in BCC tissue if the tumor had an STR somatic mutation in APC with a FC of 1.97 (95% CI 1.45–2.67, see Table S4) vs. if the BCC tissue did not have an STR somatic mutation in APC with a non-significant FC of 1.09 (95% CI −1.19–1.43), (see Figure 7, ANOVA interaction p = 0.0002).
