Newly published in the Nature Genetics journal is the research entitled: “A Genomics England haplotype reference panel and the imputation of the UK Biobank”. The paper is authored by Dr. Sinan Shi of the Department of Statistics with Professor Simon Myers of the Myer’s Group (also at the Department of Statistics) and Sir Mark Caufield from Queen Mary University of London as co-authors.
Genomics England
Genomics England (GEL) was setup by the UK Government’s Department of Health and Social Care in 2013 to implement the 100,000 Genomes Project. It is believed that through the 100,000 Project, a foundation has been laid for personalised medicine and aided in securing the NHS’s position as one of the most advance healthcare systems in the world. [1] With the 1000,000 Genomes Project, the NHS has become the first national healthcare system with routine care that offers whole genome sequencing. [2]
In December 2018, the project of sequencing 100,000 whole genomes from around 85,000 NHS patients affected by rare disease or cancer was completed. Genomics England is now working on integrating genomics into healthcare across the NHS.
The resulting high coverage sequencing dataset by Genomics England is one of the largest genetic variations resources to have been collected in the UK.[3]
The UK Biobank & Data Sample Size
The research by Dr. Shi and Prof. Meyers was carried out by building a haplotype reference panel with the GEL sequencing dataset. The resulting reference panel was based on 78,195 genomes and contained a diverse ethnic representation, with European and South Asian samples having the strongest representation.[4] With this reference, the researchers were then able to assess the high accuracy of the panel by comparing it to the HRC reference panel from the 1000 Genomes Project.
In spite of the accuracy provided by the reference panel, there is the possibility that the current UK Biobank sample size may be insufficient for the detection of cancers and rare diseases with a moderate effect size.[5] This remains the case even with the whole genome sequencing.
For GEL users and registered researchers, the GEL phase haplotype reference panel is available on the GEL platform and has been widely used. Additionally, the GEL imputed UKB data has been adopted as a UKB official imputed data resource.

What does a statistician do for the England football team?
From squad selection to modelling how footballs behave at altitude, statistician Matt Penn explains how data is helping shape the modern game, and why coaches will always matter more than the numbers.
New evidence suggests vast hidden magma systems inside Mars
Researchers from the Departments of Earth Science and Statistics have found evidence that Mars once hosted enormous, Earth-like magmatic systems deep below its surface – even though the planet lacks the plate tectonics long considered essential for this kind of geological complexity. The findings open up new possibilities for how rocky planets become habitable.
Finding a needle in the genomic haystack: Targeting rare genes using statistical outliers
In statistical modelling, extreme outliers are often written off as 'noise'. But a new study by researchers from Oxford's Department of Statistics and Big Data Institute published this week in The American Journal of Human Genetics reverses that principle, using these outliers as the basis of a targeting system for locating rare, high-impact genetic mutations.
