Location of somatic mutations in 3′UTRs.

For each somatic mutation, the percentage of the distance from the start of the 3′UTR to the somatic mutation compared to the total length of the 3′UTR was calculated. The figure shows the number of mutations in rolling windows of 5% of the 3′UTR length for somatic mutations in (A) all cancer types, (B) lung cancer, (C) SCLC, (D) melanoma, and (E) prostate cancer.
