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 v4.0 imputation reference panel of 8,554 whole genomes.

Merged imputed genotype data is composed of 96 data sets that include samples from multiple cohorts.

• Total number of individuals: 392,649

• Total number of variants (merged set): 20,175,454

• Reference assembly: GRCh38/hg38
