Quantitative traits in health and disease
Research in a Nutshell
Research in my group spans the interface of population and disease genetics, with a focus on the genetic architecture of complex traits and the identification of genetic variants influencing quantitative risk factors for common diseases such as heart disease and diabetes. I am particularly interested in high kinship isolate populations which have increased utility for rare variant discovery, but we also make use of the UK Biobank and Generation Scotland resources. I am principal investigator of the VIKING GENES studies, platform resources for health research to which we continue to recruit participants from the Northern Isles of Scotland.
My major research interest is in homozygosity and the potential role of recessive genetic variants in determining disease risk – I steer an international consortium (ROHgen) of >200 cohort studies and >1.4 M research participants, which seeks to understand the effect of inbreeding on complex traits in humans. After developing the methods to measure homozygosity and describing the global distribution, we demonstrated an effect of genome-wide homozygosity on height and cognition. More recently we showed for the first time that parental relatedness has a profound effect on fertility of the individual, and smaller effects on risk-taking traits. Moreover, we could show using sibling comparisons that this effect was causally genetic and not confounded, and that this effect is likely due to rare variants in the genome.
Together with Albert Tenesa, I have recently set up a new international study, Coronagenes, to understand the genetic factors influencing the severity and symptoms of COVID-19 coronavirus infection. Other research themes in my group include the genetics of lifespan, retinal vessel traits, dietary genetics, homozygous knockouts from sequence data, the genetics of proteomics, the contribution of the Y chromosome to complex trait variation and genetic architecture more generally in terms of heritability, pleiotropy, etc. I also run a study of Multiple Sclerosis in Orkney and Shetland, focussing both on genetics and the role of vitamin D.
A final strand of activity is in population genetics, particularly focussed on the genetic history of the British Isles, where I was the first to discover genetic evidence for Norse Viking ancestry. I recently described the fine-scale genetic structure of Britain and Ireland, focussing on Scotland. An important SW to NE divide in Scottish genetics was apparent, as well as a number of isolated populations with their own distinct gene pools – the Northern Isles, the Hebrides, the Isle of Man and County Donegal. Detailed analysis in Shetland has shown that 10% of all genetic variants found there are either unique to the islands or at least tenfold enriched there, compared to Edinburgh.
Our recent collaborations with clinical geneticists in NHS Grampian have started to reveal the consequences of these unique gene pools for the people of the Northern Isles, as certain actionable variants are at much higher frequency than elsewhere. After our initial study of a Long QT Syndrome variant in Shetland, we are now moving on to a broader survey of recessive Mendelian variants in Orkney and Shetland. We are at the forefront of applying genomic medicine in Scotland through the approved return of actionable genetic findings in our VIKING II study, as an exemplar for larger-scale studies.
