Hereditary nonpolyposis colorectal cancer (HNPCC) is one of man's commonest hereditary diseases1. Several studies have implicated a defect in DNA mismatch repair in the pathogenesis of this disease2-8. In particular, and homologues of the bacterial DNA mismatch repair genes and mutL, respectively, were shown to be mutated in a subset of HNPCC cases 9-16. Here we report the nucleotide sequence, chromosome localization and mutational analysis of and two additional homologues of the prokaryotic mutL gene. Both and were found to be mutated in the germline of HNPCC patients. This doubles the number of genes implicated in HNPCC and may help explain the relatively high incidence of this disease.
