Exome chip‐driven association study of lipidemia in >14,000 Koreans and evaluation of genetic effect on identified variants between different ethnic groups

Lipid levels in blood are widely used to diagnose and monitor chronic diseases. It is essential to identify the genetic traits involved in lipid metabolism for understanding chronic diseases. However, the influence of genetic traits varies depending on race, sex, age, and ethnicity. Therefore, research focusing on populations of individual countries is required, and the results can be used as a basis for comparison of results of other studies at the cross‐racial and cross‐country levels. In the present study, we selected lipid‐related variants and evaluated their effects on lipid‐related diseases in more than 14,000 subjects of three cohorts using the Illumina Human Exome Beadchip. A genome‐wide association study was conducted using EPACTs after adjusting for age, sex, and recruitment area. A genome‐wide significance cutoff was defined as p
