Genotypes

FinnGen individuals were genotyped with Illumina and Affymetrix chip arrays (Illumina Inc., San Diego, and Thermo Fisher Scientific, Santa Clara, CA, USA).

Chip genotype data were imputed using the population-specific SISu v3 imputation reference panel of 3,775 whole genomes.

Merged imputed genotype data is composed of 75 data sets that include samples from multiple cohorts.

• Total number of individuals: 271,341

• Total number of variants (merged set): 16,962,023

• Reference assembly: GRCh38/hg38
