Mismatch Repair Genes and Cancer - Essay ExampleThe theater of operations attempted to screen for two major parts of mutations. One type of mutation that was tested for was the loss of heterozygosity, which is a type of mutation that generates a change in the type of genetic transmission of cells. The otherwise type of mutation that was screened in the study was microsatellite instability. This mutation is usually observed in long sequences that were composed of tell segments. These two types of mutations were considered to be important in determining whether a certain gene does influence the organic evolution of cancer.The study was conducted in a Portugese hospital, wherein approximately 287 patient subjects participants. These patients were already diagnosed to have breast cancer. In addition, in that location were 547 individuals who also participated in the study as controls, or individuals who were pre-determined to be normal and healthy. The study wanted to theme the cha nces of developing breast cancer based on the presence and number of mutations in the MMR genes that were studied.The MMR genes tested in the investigation included the mismatch repair genes of the MSH family, as well as that of the MLH family. The PMS1 and MUTYH were also other genes that belonged to the MMR class of repair genes.
