The Applied Biosystems Axiom PangenomiX Array is a human genotyping research array designed for whole-genome imputation with diverse and global population coverage. It is a valuable research tool for human genomics, including applications such as genome-wide association studies (GWAS), population health initiatives, polygenic risk score research and development, and clinical research for trials in drug discovery. The Axiom PangenomiX Array can scan the whole genome from as little as 100 ng genomic DNA. It can enable target single nucleotide polymorphism (SNP) identification, copy number variant analysis, human leukocyte antigen (HLA) typing and more in a single, cost-effective assay with ready-to-use data analysis.

Ethnic diversity at your fingertips—the largest population coverage on a high throughput array

More than 800,000 markers were selected for high genomic coverage from the 1000 Genomes Project phase 3, yielding coverage for European, African, admixed American, East Asian, and South Asian populations. This means variants prevalent in different populations can be accurately represented and accounted for, leading to more inclusive research outcomes.


In addition to markers selected specifically to maximize imputation power and ethnic diversity, additional markers were chosen from broadly referenced public databases, including ACMG 73, ClinVar, NHGRI-EBI GWAS catalog, CPIC, PharmGKB, and PharmaADME, and can be directly genotyped for each sample.


The Axiom PangenomiX Array also offers CNV analysis for fixed genomic regions and de novo copy number discovery to detect copy number changes across the whole genome. The Axiom PangenomiX Plus Array enables genotyping of markers of important genes in difficult-to-genotype regions, such as pharmacogene CYP2D6, and comes with Pharmacogenomic Translation Reports with general metabolizer status.

Comprehensive array content for your research

Imputation to enhance accuracy and coverage

The Axiom PangenomiX Array includes over 800,000 markers in the GWAS module. Common variants are intelligently selected via a proprietary imputation-based marker selection strategy for genome-wide coverage in the five major ancestral populations. This process allows access to a vast number of low frequency markers (minor allele frequency [MAF] >1%) and common markers (MAF >5%) for any given population, through imputation. The intelligent, imputation-aware design helps ensure that the selection of markers offers high imputation accuracy across all ancestral populations. The autosomal markers in the GWAS grid are valuable in ascertaining the ethnic breakdown of individuals genotyped with the Axiom PangenomiX Array. Combined with the mitochondrial and Y chromosome markers, the Axiom PangenomiX Array is a powerful array for determining ancestry and migration patterns in genetic testing.
