Obesity is a serious international health problem that increases the risk of several common diseases. The genetic factors predisposing to obesity are poorly understood. A genome...

What can mendelian randomisation tell us about modifiable behavioural and environmental exposures?

Using genetic variants as a proxy for modifiable environmental factors that are associated with disease can circumvent some of the problems of observational studies

Mendelian randomization: can genetic epidemiology help redress the failures of observational epidemiology?
