title: Whole genome genotyping technologies on the BeadArray platform.
abstract: The ability to simultaneously genotype hundreds of thousands of single-nucleotide polymorphisms (SNPs) in a single assay has recently become feasible due to innovative combinations of assay and array platform multiplexing. In this review, we describe the development of the Infinium whole genome genotyping technology and the BeadArray platform. We discuss the automated use and performance of a series of genotyping BeadChips, including data quality, technology scalability, and flexibility in designing array content. We describe high-density tag SNP-based Bead-Chips and various multi-sample BeadChip configurations with their respective applications. These technologies are enabling large-scale whole genome association studies that have the potential to revolutionize our ability to detect common genetic variants with a significant role in identifying disease-associated loci, proteins, biomarkers, and pharmacogenomic responses.
