Human gene mutation in pathology and evolution.
Mutations in human gene pathology and evolution represent two sides of the same coin in that the same mechanisms that have frequently been implicated in disease-associated mutagenesis appear also to have been involved in potentiating evolutionary change. Indeed, the mutational spectra of germline mutations responsible for inherited disease, somatic mutations underlying tumorigenesis, polymorphisms (either neutral or functionally significant) and differences between orthologous gene sequences exhibit remarkable similarities, implying that they may have causal mechanisms in common. Since these different categories of mutation share multiple unifying characteristics, they should no longer be viewed as distinct entities but rather as portions of a continuum of genetic change that links population genetics and molecular medicine with molecular evolution.
