| Outline of Final Research Achievements |
Some of colorectal polyposis patients without detectable germline APC mutations are considered to carry germline mutations in the MUTYH gene. Because limited information is available on MUTYH variants and their contribution to polyposis, we investigated whether 14 polyposis patients without detectable germline APC mutations carried germline MUTYH mutations. Somatic APC mosaic mutations were detected in three polyposis cases (21%) and no biallelic germline MUTYH mutations were detected. Three patients had an IVS10-2A>G MUTYH heterozygous mutation. We investigated the allele frequency with 115 controls over 70 years of age without cancer history. The allele frequency was 0.022 (5 variants). The odds ratio of IVS10-2A>G was 5.4 (95% confidence interval: 1.22-24.0). Though our sample size is too small to make a definitive conclusion, the odds ratio was significantly higher in case group. Further analysis was required to assess the risk of variant for colorectal polyposis.
