Abstract

Knowledge of cancer genomic DNA sequences has created unprecedented opportunities for mutation studies. Computational analyses have begun to decipher mutational signatures that identify underlying causes. A recent analysis encompassing 30 cancer types reported 20 distinct mutation signatures, resulting from ultraviolet light, deficiencies in DNA replication and repair, and unexpectedly large contributions from both spontaneous and APOBEC-catalyzed DNA cytosine deamination. Mutational signatures have the potential to become diagnostic, prognostic, and therapeutic biomarkers as well as factors in therapy development.
