Molecular abnormalities in colorectal cancer: Microsatellite instability pathway

Research output: Contribution to journalArticlepeer-review

3 Scopus citations


The expansion and contraction of microsatellite DNA in colon cancer (microsatellite instability) has provided the first strong experimental support for a mutator phenotype in cancer. As a result of this and other key observations, several human DNA mismatch repair genes, in particular hMLH1 and hMSH2, have now been implicated in this process. Tumors harboring such a mutator phenotype appear to have distinctive genetic, pathologic, and clinical characteristics.
