Abstract excerpt
Ultra-low-depth sequencing (ULDS) is a cost-effective strategy for large-scale genomic studies, but its utility hinges on accurate genotype imputation. This study evaluates three imputation tools -- STITCH, QUILT2, and GLIMPSE2 -- across varying sequencing depths and sample sizes, using the China Kadoorie Biobank (CKB) and The 1000 Genomes Project (1KGP) East Asian (EAS) reference panels. Critical performance...
