| Outline of Final Research Achievements |
We aimed to identify the anti-oncogene, which should be the causative gene of familial cases of elastofibroma dorsi. All gene variations were selected by the subtraction of genome mutations between the tumor tissues and the peripheral-blood genome of several elastofibroma dorsi cases. The target causative gene should have mutated in both peripheral blood genome and tumor cells in the different way. However, the genome variations of the people living in the Aguni Island, where elastofibroma dorsi occurs frequently, were very similar among cases, and lacking in diversity. By the procedure, in which we choose the genome variation of the usual existence coefficient of 1% or less, it became clear by making the whole Japanese's average genome as a standard genome, it could not narrow down easily. We are now looking for the putative causative gene by PCR amplification from previous many pathological paraffin fixed blocks.
