There is mounting evidence for an age-dependent accumulation of somatic mutations as a result of the inherent imperfection of DNA replication and repair. A possible age-related decline in genome maintenance systems may exacerbate this age-related loss of genome integrity. A review of the current methods of mutation detection is timely in view of the lack of insight as to the magnitude of somatic mutation accumulation, the types of mutations that accumulate, and their functional consequences.
