The array consists of 736,145 probes for 655 973 markers. In addition to the core GWAS markers it contains 116,402 coding markers enriched in Finland, specific markers for the HLA region, ClinVar markers, pharmacogenomic markers and selected markers that were of special interest for partners.

The marker content of the FinnGen ThermoFisher Axiom custom array v2 (current version) can be downloaded from here. The content for v1 is downloadable from here.

The legacy samples have previously been genotyped over the years using various generations of Illumina GWAS arrays. All GWAS data is imputed against a Finnish population specific whole genome sequence (WGS) backbone.
