Highlights
► European, East Asian, African American and Latino race/ethnicity optimized arrays. ► High density genotyping arrays for large-scale genome-wide association studies. ► Novel design alternates rounds of pairwise SNP selection and imputation coverage. ► Increased SNP density achieved by reduced redundancy of high performing SNPs.
