Illumina Infinium Global Diversity Array

Illumina has launched the Infinium Global Diversity Array, the commercial version of the array designed for use in the National Institutes of Health All of Us research program. The array features about 1.9 million variants, including imputation-optimized tag SNPs and up-to-date clinical research content from public databases such as ClinVar, the National Human Genome Research Institute-EBI database, and Pharmacogenomics Knowledgebase (PharmGKB). The array has broad utility for a variety of large-scale screening and association studies, with content relevant for polygenic risk scoring, common-disease association studies, and inherited risk screening, Illumina said. In addition, the array offers extremely high genomic coverage and imputation performance across 26 diverse populations. It comes in an eight-sample format chip that has room to add up to 175,000 custom beadtypes, the company said.
