NHS genomic medicine service data release v1 (15/06/2022)

Data dictionary


This document provides a description of the NHS GMS data release v1 dated June 15th 2022.

Each progressive release incorporates new content, enhances existing content, and enables more effective use of the data.

This data are presented within the Genomics England Research Environment, accessed via the AWS virtual desktop interface and subject to all Genomics England data protection and privacy principles.

Please see the Research Environment User Guide for detailed documentation on how to use and query the Genomics England dataset. This page also includes instructional videos which can not be viewed from within the Research Environment.

Release overview

The NHS Genomic Medicine Service (GMS) Data Release Version 1 provides clinical data for 308 participants which are part of 127 referrals. In summary, this release includes 324 genomes from 308 participants. There are 292 genomes from 292 rare disease programme participants and 32 genomes from 16 cancer programme participants.

We further provide tiering data from 111 referrals, and 110 of these are represented in the GMC Exit Questionnaire. Within the GMC Exit Questionnaire, cases are included up to 19-03-2022. In addition, this release includes 111 interpretation requests from the Rare Disease program and 16 interpretation requests from the Cancer program.

The intended audience for this document is researchers that have access to the Genomics England Research Environment.

Identifying this data release

The clinical data, secondary data, and tabulated bioinformatic data for this data release, and the paths to the applicable genome files, are found in the following LabKey folder:


Subsequent releases will be identified by an incremental increase in the version number and the date of data release.

Relevant genomic data produced by the Genomics England Bioinformatics pipeline (i.e. joint-called VCFs, annotated somatic VCFs) can be found in the your home directory, under the folder gel_data_resources and then gms.


For this initial release, v1, the inclusion criteria are as follows:

  • Participant has been through a manual consent audit and passed
  • Only those participants who had all of their consent documents audited, and all documents consistently confirmed that they were eligible (they had both discussed and consented to inclusion in the NGRL, and were consented as an adult or child) are included.
  • Any participants who were consented as children but were already 16 at the time of consent, or have since turned sixteen (but are not deceased) are deemed ineligible.
  • Participant is part of an eligible referral
  • Eligible referrals refer to closed cases that contain at least one eligible participant.
  • Where a referral contains a mix of eligible and ineligible participants, the referral is not considered eligible and all its participants have been removed from this release.

In scope

Below we provide an overview of the data in scope for this release. By definition, this relates to cancer and rare disease data for participants enrolled in NHS GMS that consented for research. These data include:

  • Genomic data for participants when available.
  • This data contains closed case data only. This means that all referrals have gone through interpretation.
  • Whole genome sequencing (WGS) family-based quality control for rare disease.
  • Outputs of the Genomics England Bioinformatics rare diseases interpretation pipeline
  • Tiering data – rare disease
  • Exomiser results for interpreted genomes – rare disease
  • GMC outcome data ("exit questionnaire data") – rare disease - up until 19/03/2022.
  • Outputs of the Genomics England Bioinformatics cancer interpretation pipeline
  • 'Gold standard' cancer genomes which have been through interpretation and passed quality checks
  • Annotation and tiering of small variants
  • Primary clinical data, including recruited disease and primary tumour types

Out of scope

Additional time is required to update the applications/tools that are available in the RE to the current data release, e.g. IVA, Participant Explorer. Please refer to the Application Data Versions page for the data release version used in the RE products and services.

Data out of scope for this release:

  • Clinical and genomic data for participants that have withdrawn from research after enrolment to the Genomic Medicine Service, or were otherwise ineligible.
  • Participant data from the pilot phases of the 100,000 Genomes Project (i.e. not main programme).
  • Participant data from the 100,000 Genomes Project (main programme).
  • There are no secondary datasets available for this release.

Quality notes

This section will be amended for future releases as more documentation becomes available.

Note on Labkey platekey query limitations

Aggregation or Distinct queries including specifically the platekey column (e.g. SELECT DISTINCT participant_id, platekey FROM <table_name>) in Labkey will intentionally fail with a 'Status code = 500' error , UnauthorizedException or 'Unable to locate required logging column Key'. This can initially be circumvented by pulling in the entire data with SELECT * FROM <table_name> and subsetting or filtering your data downstream. We will continue to monitor the impact of the issue.

Terms of use for specific cohorts

For NHS GMS Data Release Version 1, no cohort has been formally linked to the data. This will change in future releases and the Terms of Use for Specific Cohorts will be amended.
