It especially covers the common and rare variations unique to China.
1. The first human population-specific whole genome chip. The optimized tag SNP content comes from all three stages of HapMap and the 1000 person genome project (1kgp), which can be used to explore new disease and character association in Chinese ethnic groups.
2. In particular, 81% of the common variants (MAF > 5%) and 60% of the rare variants (MAF > 2.5%) in China are suitable for genome-wide association studies (GWAS).
3. The bearaytm technology patented by Illumina can provide very high data quality, with an average detection rate of > 99%, and a repetition rate of > 99.9%.
