# Genetic data

Information about the genetic data in Our Future Health resource, including the genotype array data, imputed genetic data, genetic ancestry data and genetic kinship data.

The same participants are represented in all datasets listed below.

#### **Genotype array data**

The [genotype array data](/our-future-health/data-types/genetic-data/genotype-array-data.md) release contains information on 686,416 variants for 755,000 participants ([release 14](/our-future-health/data-releases/2026-data-releases/release-14.md), May 2026). These data were obtained using a custom Illumina Infinium Excalibur beadchip array, designed by Our Future Health in collaboration with Illumina.

#### **Imputed genotype data**

The [imputed genotype data](/our-future-health/data-types/genetic-data/imputed-genotype-data.md) release contains information on 159,587,100 variants for 755,000 participants ([release 14](/our-future-health/data-releases/2026-data-releases/release-14.md), May 2026). Imputation was performed using the UK Biobank 200k phased whole genome sequencing data as a reference panel.

#### **Genetic ancestry data**

[Genetic ancestry data](/our-future-health/data-types/genetic-data/genetic-ancestry.md) has been inferred for 755,000 participants ([release 14](/our-future-health/data-releases/2026-data-releases/release-14.md), May 2026) by applying a Global Ancestry Estimation (GEA) workflow developed by Genomics Ltd. 

#### Genetic kinship data

[Genetic kinship data](/our-future-health/data-types/genetic-data/genetic-kinship.md) has been inferred for 755,000 participants ([release 14](/our-future-health/data-releases/2026-data-releases/release-14.md), May 2026).
