摘要: Abstract Hereditary nonpolyposis colorectal carcinoma is a major cancer susceptibility syndrome known to be caused by inheritance of mutations in at least four genes such as hMSH2, hMLH1, hPMS1 , and hPMS2 which encode components DNA mismatch repair system. The hMLH1 genomic locus on chromosome 3p has been cloned shown cover ∼58 kilobases contain 19 exons. sequence all the intron-exon junctions determined used develop methods for analyzing each exon mutations. Using these analyze 3p-linked hereditary kindred, we have demonstrated that this family due frame shift mutation gene.
