Abstract excerpt
OBJECTIVE: To identify the MLH1 and MSH2 gene mutation in two hereditary nonpolyposis colorectal cancer (HNPCC) families. METHODS: Polymerase chain reaction and DNA sequencing were used to screen for MLH1 and MSH2 gene mutation, and PCR-restriction fragment length polymorphism and DNA sequencing were performed to confirm the mutation. RESULTS: By DNA sequencing, a novel mutation of c.243_244insA located at the...
