Design of Tag SNP Whole Genome Genotyping Arrays

Open publisher page 13 citations

Abstract

Whole genome association studies have recently been enabled by combining tag SNP information derived from the International HapMap project with novel whole genome genotyping array technologies. In particular, Infinium whole genome genotyping (WGG) technology now has the power to genotype over 1 million SNPs on a single array. Additionally, this assay provides access to virtually any SNP in the genome enabling selection of optimized SNP content . In this chapter, we provide an overview of the tag SNP-based selection strategy for Infinium whole-genome genotyping BeadChips, including the Human 1 M BeadChip. These advances in both SNP content and technology have enabled both large-scale whole-genome disease association (WGAS) and copy number variation (CNV) studies with the ultimate goal of identifying common genetic variants, disease-associated loci, proteins, and biomarkers.
