The results of the analysis of the R(5mC)GY sites in the bves,cacna2d3, cpeb1, epha7,galr, and tfpi2 genes show that the Cq values(23–27) for most tumor DNA samples are on average three or more cycleslower than those for the corresponding DNA samples derived from healthytissues. The gene discussed is TFPI2; the disease is neoplasm.
