To understand the genetic contribution to common diseases and traits, it is vital to understand where in the genome are the most critical genomic variants, their nature and frequencies, and how much each locus contributes to the disease/trait. Many methods have been proposed to address these questions We aim to investigate the validity of existing methods as well as develop new ones to better our understanding. Diseases and traits to be studied include: asthma, diabetes, blood pressure, self-report cancer, anthropometric measures, cognitive abilities, allergy, education attainment, neuroticism score, depression, use of glasses, self-reported health, and hearing difficulties. Through the research we aim to better understand the contribution of common variants to common diseases and traits. For example, we aim to understand whether loci with reasonably large effect sizes exist that can be harnessed for better disease prevention or treatment. This type of information is crucial for directing future research directions as well as developing more personalized treatment and prevention strategies. Methods have been developed to partition the genome into regions and quantify the contribution each region makes to the disease/trait. These methods will be applied to the data, as well as new ones proposed by the applicants. Simulation studies will be carried out to examine the validity of the methods. If the methods are found to be robust and reliable, inferences about the contribution of each genomic locus to the disease/trait will be drawn. The full cohort.
