The UK Biobank Axiom Array Content Summary document provides an overview of the content of the UK Biobank Axiom Array (which comprises 820,967 genetic markers). This document summarizes the array design philosophy and the 3 major categories of interest (markers of specific interest, rare coding variants, and genome-wide coverage) that are then subdivided into more specific categories. It also details the number of markers in each sub-category and includes a short description of how the markers were selected. Further detail about the coverage of the array, including imputed genetic coverage can be found here: Further details of the UK Biobank Axiom Array
How to find out whether your SNPs of interest are on the UK Biobank Axiom Array

Specific queries – tagged and imputed SNPs
To make an enquiry to determine if your marker(s) of interest is tagged or imputed please submit the query form below.
UK Biobank Axiom Array query form
You are able to submit a list of markers (up to 50 inputs) in any one of the following 3 formats:
- RSIDs (eg rs184985767, rs 1800024)
- Official HUGO geme symbols (eg CCR5, MYH7)
- Chromosome position (eg 3:46412559-46412560, 17:24036-49783)
You will also need to specify your population of interest – see the list here.
The results from enquiries are provided as number of markers, SNPs or indels, in a table format:
- Direct – markers directly tiled on the array
- Tagged – markers that can be pairwise tagged in a specified population at R2≥0.8
- Imputed – markers that can be imputed for a specified population at an R2≥0.8
Please specify the category or sub-categories of interest as outlined in the Axiom Array Content Summary document and send this query to the Access Team.
Results will be provided in an Excel or csv file format.
Other enquires will be handled on a case by case basis and may require additional time to process the request.
