In 2001, the Human Genome Project built the first human reference genome. In 2008,the 1000 Genomes Project was launched. Whole-genome sequencing was performed on 2,500 samples of different races around the world, and the most detailed human genome variation map has been drawn to date, including 84.7 million SNPs, 3.6 million indels, and 60,000 structural variation sites. Due to the significant differences in genomic variation sites and frequencies among different races,nations have launched their own genome sequencing programs to discover the population-specific genomic variations and establish more accurate reference genomes to serve the health and medical fields.
