Genetics and genomics in Peru: Clinical and research perspective

Abstract

Peru is a pluricultural and ethnically diverse country located in middle west of South America. It is the fourth largest country (1,285,216 km2) in area in South America, bordered in the north by Ecuador and Colombia, in the south by Chile, south east by Bolivia, by Brazil in the east and by the Pacific Ocean in the west. Peru has one of the most diverse climates, geographical and ecological in the world, from tropical or subtropical dessert to glacial in highland mountains to Amazon jungle. Peru is divided into 24 geopolitical regions with a central government. According to last national census in 2017, Peruvian populations accounts for 31,237,385 inhabitants (Instituto Nacional de Estadistica e Informatica [INEI], 2017). Most of Peru's population lives in the Coastal area, with almost one third of the nation's population living in Lima, the largest city with approximately 11 million people. Rural and urban population has changed over the last 50 years due to migration waves in the 1950s from rural to urban sites mainly located in the coast causing decrease or disappearance of native communities.
