# Genotypes

FinnGen individuals were [genotyped](https://finngen.gitbook.io/documentation/r2/methods/genotype-imputation) with Illumina and Affymetrix chip arrays (Illumina Inc., San Diego, and Thermo Fisher Scientific, Santa Clara, CA, USA).&#x20;

Chip genotype data were [imputed](https://finngen.gitbook.io/documentation/r2/methods/genotype-imputation/genotype-imputation) using the population-specific [SISu v3 imputation reference panel](https://finngen.gitbook.io/documentation/r2/methods/genotype-imputation) of 3,775 whole genomes.&#x20;

Post-imputation QC involved excluding variants with imputation INFO < 0.7.

* Total number of individuals: 102,739
* Total number of variants (merged set): 17,054,975
* Reference assembly: GRCh38/hg38
