Variation in the human genome and the inherited basis of common disease.

摘要

The availability of a reference human genome sequence-an increasingly dense catalog-knowledge of common genetic variation, and new developments in technology present an unprecedented opportunity to systematically explore the genetic basis of complex human diseases such as cancer. An understanding of the common mutations that can cause distinct human cancers will be critical for identifying new targets for drug discovery, patient stratification for clinical trials, and analysis of drug response data to delineate classes of patients that respond to therapy. The genome structure of cancer can be investigated in several ways. Germline mutations can be investigated in large-scale, case-control, or family studies. Somatic alternations can be identified using state-of-the-art genomic technologies such as high-density oligonucleotide arrays and targeted resequencing. Combined, these approaches will lead to a better understanding of the cancer genome.
