The mutations in the DPH3 promoter tend to co-occur with TERT promoter mutations more frequently than expected by chance in melanoma (OR = 3.0, 95% CI 1.4 - 6.4, P = 0.006), BCC (OR = 3.4, 95% CI 1.5 - 7.6, P = 0.003) and SCC (OR = 4.3, 95% CI 0.9 - 20.2, P = 0.06; Figure 2). Here, TERT is linked to skin basal cell carcinoma.
