How hereditary diseases remain from generation to generation

Some high-risk gene variants, such as those for Alzheimer's disease or cancer, can persisted in the population for a long time without disappearing and researchers have now discovered why these harmful gene variants do not get weeded out by natural section in the course of evolution. The same process responsible for helping us fend off pathogens, may help the occurrence of mutations in our genome that predispose us to hereditary diseases, the researchers found. Scientists describe this process that help harmful [...]
