Family Cancer Syndromes: Inherited Deficiencies in Systems for the Maintenance of Genomic Integrity

Familial cancer syndromes have revealed important fundamental features regarding how all cancers arise through destabilization of the genome, such that somatic evolution can select for the disruption of critical cellular coordinating and regulatory features. The authors examine those cellular genes and systems whose normal role is to preserve genomic integrity and relate them to the genetic foundations of heritable cancers. By examining how these cellular systems normally function, how family cancer genes are able to affect the process of tumor progression can be learned. In so doing, a clearer picture of how sporadic cancers arise is additionally gained.
