TLDR
Assessment of clinical findings can improve the rate of detection of mutations of DNA mismatch-repair genes in families suspected of having hereditary nonpolyposis colorectal cancer.
Abstract
Background Germ-line mutations in DNA mismatch-repair genes (MSH2, MLH1, PMS1, PMS2, and MSH6 ) cause susceptibility to hereditary nonpolyposis colorectal cancer. We assessed the prevalence of MSH2...

New clinical criteria for hereditary nonpolyposis colorectal cancer (HNPCC, Lynch syndrome) proposed by the International Collaborative group on HNPCC.

TL;DR: The establishment of a set of selection criteria for families with hereditary nonpolyposis colorectal cancer (HNPCC, Lynch syndrome) to provide a basis for uniformity in collaborative studies and a definition of HNPCC was proposed that was aimed at helping clinicians to identify families.

Recommendations for the Care of Individuals With an Inherited Predisposition to Lynch Syndrome

TL;DR: Burke et al. as mentioned in this paper published an article in JAMA that set forth recommendations for care of individuals with an inherited predisposition to hereditary nonpolyposis colorectal cancer (HNPCC).
Journal ArticleDOI

Hereditary Cancer Predisposition Syndromes

TL;DR: The most common hereditary cancer syndromes, most attributable to genes inherited in an autosomal dominant manner with incomplete penetrance, and a number of rare syndrome in which particular progress has been made are highlighted.

Lessons from Hereditary Colorectal Cancer

TL;DR: The authors are grateful to the members of their laboratories for their contributions to the reviewed studies and to F. Giardiello and S. Hamilton for photographs of colorectal lesions.

Microsatellite instability in cancer of the proximal colon

TL;DR: Colorectal tumor DNA was examined for somatic instability at (CA)n repeats on human chromosomes 5q, 15q, 17p, and 18q, and this instability was significantly correlated with the tumor's location in the proximal colon and with increased patient survival and loss of heterozygosity.

Ubiquitous somatic mutations in simple repeated sequences reveal a new mechanism for colonic carcinogenesis

TL;DR: It is shown that 12 per cent of colorectal carcinomas carry somatic deletions in poly(dA . dT) sequences and other simple repeats, and it is concluded that these mutations reflect a previously undescribed form of carcinogenesis in the colon mediated by a mutation in a DNA replication factor resulting in reduced fidelity for replication or repair (a 'mutator mutation').

Clues to the pathogenesis of familial colorectal cancer

TL;DR: Molecular features of "familial" cancers were compared with those of sporadic colon cancers, and a mechanism for familial tumorigenesis different from that mediated by classic tumor suppressor genes is suggested.

Inactivation of the Type II TGF-β Receptor in Colon Cancer Cells with Microsatellite Instability

TL;DR: Human colon cancer cell lines with high rates of microsatellite instability were found to harbor mutations in the type II TGF-beta receptor (RII) gene, which links DNA repair defects with a specific pathway of tumor progression.
