Understanding our genetic variation

High-throughput arrays for identifying nucleotide and structural changes in the human genome

Human Genotyping

To date, human genotyping efforts have identified thousands of associations between genetic variants and diseases or traits, and created maps of the unique variation within populations. Microarrays are the ideal platform for assessing known markers in the human genome, enabling researchers to find single nucleotide polymorphisms (SNPs) or larger structural changes among millions of markers.

With Illumina human genotyping arrays, you can choose expertly designed content, use consortium-developed markers, or customize array content according to your research objectives. Our microarray solutions provide trusted performance and support high-throughput, multiplex processing for large-scale population studies, clinical research, and other human genotyping projects.

Illumina human genotyping arrays offer several advantages.

  • Trusted data quality with widely adopted Infinium technology
  • High resolution for detecting copy number variation (CNV), loss of heterozygosity (LOH), and insertions/deletions
  • Coverage of common and rare variants as well as diverse global populations
  • High-throughput, multiplex array processing
  • Low per-sample cost
  • Integration with Illumina sequencing systems for multi-omics analyses
