2 Background: It is now known that a proportion of cases of hereditary non-polyposis colorectal cancer (HNPCC) is caused by mutations in the human homologue of the yeast DNA mismatch repair gene MSH2. A proline to leucine change due to a C to T transition in codon 622 of hMSH2 has been identified in a large HNPCC family of over 240 individuals. This information will frequently identify a hereditary colorectal cancer syndrome in the family, should it exist.
