Common (complex) traits

Most people, have come across complex traits such as heart rate, eye colour and height. But they also include common human diseases such as hypertension (high blood pressure), diabetes, and coronary heart disease.

We analyse available genomic data in phenotyped human populations to identify genes associated with these traits and diseases. These studies have provided a greater understanding of the biology linking genotype and phenotype (the traits that we see and measure).

The exciting thing about these studies is the capability to screen for trait-associated genes in the general population at high-resolution, and in an unbiased manner to find regions or genes that we may never have thought to look at.

Using this information we can begin to create ‘polygenic risk scores,’ which allows stratification of a population into groups with very different trajectories of lifetime risk.

Importantly, these genetic association studies have reinforced known disease associations and also suggested additional ones that could reveal unrecognized biology which may ultimately guide new therapies.

CARDIOVASCULAR TRAITS

We work on multiple cardiovascular traits, in particular electrocardiographic traits. An electrocardiogram (ECG) is a test which measures the electrical activity of your heart to show whether or not it is working normally. An ECG records the heart's rhythm and activity on a moving strip of paper, or a line on a screen. Through international collaborations (as part of the CHARGE Consortium) we analyse large population datasets with ECG measures and genomic data, and have successfully uncovered many new gene regions that play a role in determining the hearts electrical function.
