The Infinium Global Diversity Array-8 Kit is the recommended replacement for the Infinium Multi-Ethnic Global, Multi-Ethnic AMR/AFR, and Multi-Ethnic EUR/EAS/SAS Kits, which have been discontinued. The Global Diversity Array is an updated version of the Multi-Ethnic Kits.

Overview

The Infinium Global Diversity Array 8-Kit (GDA) BeadChip is a powerful, cost-effective array with optimized, multiethnic, genome-wide content.

Key features

  • Updated broad coverage of clinical research variants for a range of applications

  • Optimized content enables diversity in studies

  • High-throughput, scalable workflow allows users to gather and report data quickly

Chosen by the All of Us program

The GDA is the commercial version of the microarray trusted by this NIH precision medicine initiative, which will collect data from > 1M people to improve health outcomes.

Maximized variant coverage

A high-density SNP global backbone for cross-population imputation coverage of the genome enables polygenic risk score development and characterization of genetic architecture in diverse populations.

 

Multiethnic content

The robust genome-wide scaffold was designed to tag common and low-frequency variants in global populations through collaborations with the Consortium on Asthma among African-ancestry Populations in the Americas (CAAPA) and Population Architecture using Genomics and Epidemiology (PAGE). Content includes > 1K whole-genome sequences of African ancestry and populations throughout the Americas.

Required products

Match your chosen kit size to the number of samples you run at a time. Each kit is processed as a single batch and is not designed to be divided across multiple experiments. If you are processing several low-throughput batches, order multiple small kits.

You can choose to customize your content using DesignStudio or select from a list of optional add-on content available as consortia boosters. Booster add-on content is available for:

  • Neurodegenerative diseases (~75K SNPs)

  • Oncology (~90K SNPs) 

  • Carrier screening (partnership with Igentify for interpretation)

Check with your sales rep to confirm availability and pricing.
