Somatic mutations in human cancer: insights from resequencing the protein kinase gene family.
All cancers arise due to the accumulation of mutations in critical target genes that, when altered, give rise to selective advantage in the cell and its progeny that harbor them. Knowledge of these mutations is key in understanding the biology of cancer initiation and progression, as well as the development of more targeted therapeutic strategies. We have undertaken a systematic screen of all annotated protein kinases in the human genome for mutations in a series of cancers including breast, non-small-cell lung, and testicular cancer. Our results show a wide diversity in mutation prevalence within and between tumor types. We have identified a mutator phenotype in human breast previously undescribed. The results presented from sequencing the same 1.3 million base pairs through several tumor types suggest that most of the observed mutations are likely to be passenger events rather than causally implicated in oncogenesis. However, this work does provide evidence for the likely existence of multiple, infrequently mutated kinases.
