The genome contains the hereditary information of all living cells in an organism and that includes the potential diseases inherited from previous generations. The Human Genome Project (HGP) started as an international project and in 2003 it came up with the human genome map.
More recently Next Generation Sequencing (NGS) technologies and Artificial Intelligence software are making possible a new era of personalized genome sequencing and predictive medicine that estimates the risk of disease even decades before it exists, providing individuals with a recommended medicine and lifestyle to prevent the occurrence of the disease. It allowed, for instance, the early detection of the BRCA1 gene variant to a movie star as it increased the probability of breast cancer to 87%.
Also, the cost per genome has decreased exponentially for the last 10 years and predictive medicine has become a health service affordable to individuals.
