BACKGROUND Failure in the DNA mismatch repair system is commonly accompanied by microsatellite instability and leads to colorectal cancer. The aim of this study was to find the most frequent of five mononucleotide markers in order to devise the simplest diagnostic strategy for identification of patients with hereditary nonpolyposis colorectal cancer (HNPCC) who were defined by defects in mismat...
The MutLalpha heterodimer formed by mismatch repair (MMR) proteins MLH1 and PMS2 is a major component of the MMR complex, yet mutations in the PMS2 gene are rare in the etiology of hereditary nonpolyposis colorectal cancer. Evidence from five published cases suggested that contrary to the Knudson principle, PMS2 mutations cause hereditary nonpolyposis colorectal cancer or Turcot syndrome only w...
BACKGROUND Genetic testing to refine cancer risk is available. However, little is known about factors affecting the uptake of testing for the most common hereditary colon cancer, hereditary nonpolyposis colorectal cancer. This study investigated attitudes, intentions, and uptake of genetic testing within newly identified families with hereditary nonpolyposis colorectal cancer. METHODS Cohort ...
