Objectif
Very large genetic studies have been undertaken to study the effect of genetic variations on obesity. While Body Mass Index (BMI) is 40-70% heritable genome-wide association studies (GWAS) including over 300,000 individuals revealed only less than 6% of this heritability. During the course we will review many possible explanations where the remaining heritability is hiding.
Contenu
The tutorial will give a general overview on genetic association studies. Both computational methods and several clinical studies will be explained in details. Many open questions will then be discussed with the students: How to find rare genetic variants impacting obesity? How to detect many more hiding variants with very small effects? Do genetic effects change with age? How can genetic effects be modified? What are the major consequences of obesity?
