Whole genome sequencing and whole exome sequencing of mucosal melanoma


ABSTRACT: We conducted whole genome sequencing of 5 mucosal melanomas and their matched DNA from blood. We conducted whole exome sequencing of a further 5 mucosal melanomas and their matched DNA from blood.

Mucosal melanoma displays distinct clinical and epidemiological features compared to cutaneous melanoma. Here we used whole genome and whole exome sequencing to characterize the somatic alterations and mutation spectra in the genomes of ten mucosal melanomas. We observed somatic mutation rates that are considerably lower than occur in sun-exposed cutaneous melanoma, but comparable to the rates seen in cancers not associated with exposure to known mutagens. In particular, the mutation signatures  ...[more]
