Personalized medicine in Latin America.

[ ]in the same period, genetic, molecular biology and omics data on humans has increased exponentially, leading us to a new level of understanding of the role that genes and environmental factors have on human health and disease [ ]under the perspective of personalized medicine, this new taxonomy will need to be adjusted based on any specific population-based genetic/genomic data [ ]researchers in the field of clinical medicine, genetics, molecular biology and genomics will need to merge their knowledge by population or ethnicity so that the new taxonomy can support the paradigm of precision medicine in all countries [ ]genotypes have achieved a complete biological adaptation in the indigenous host populations reflected by the fact that occult hepatitis B virus infection is common, chronic disease is benign and the relative incidence of virus-related liver cancer is low (13) Based on our experience in the field of personalized medicine, the specific genetic susceptibility and environmental interactions among the Latin American populations involved in noncommunicable or infectious diseases may lead to a deviation of the natural history and clinical outcome of these entities
