The definition of genomic medicine is the identification of variations in the human genome that confer the risk of developing common diseases, which will lead to a more individualized, more preventive, more predictive practice of medicine. This new discipline offers major benefits for health care since it will enable the identification of individuals at risk of developing common diseases before the onset of symptoms and thus prevent or delay their manifestations, complications, and consequences.

Moreover, it will lead to new treatment strategies such as pharmacogenomics, resulting in more effective and less toxic drugs, and based on the genomic structure of each population.

The next challenges facing genomic medicine include: knowledge and analysis of sequences that increase the risk or susceptibility of developing multifactorial diseases and the study of their frequency in populations. This will permit the identification of individuals with DNA sequences that put them at high risk of developing common diseases such as hypertension, type II diabetes mellitus, asthma, acute myocardial infarction, and some infectious diseases, among others, that are becoming more relevant in our country due to epidemiological transitions.
