Summer School on Genetic Epidemiology 2024 in Davos

June 13 – June 15, 2024


This summer school aims at providing guidelines on optimal practice in designing, analyzing, and interpreting genetic epidemiological studies, for those who would like to actively analyze DNA sequencing from whole genome sequencing or whole exome sequencing studies (NGS), genome-wide association studies (GWAs), candidate gene or even single genetic marker studies. Knowledge and awareness about all steps of a genetic epidemiological study, including planning, data preparation, quality control or statistical analysis will be considered as this is crucial for the cost-efficient use of these data. Special attention will be given to data generation and quality control procedures of sequencing and genotyping technologies. Confounding due to population heterogeneity, i.e., population stratification, or multi-ethnic populations and cryptic relatedness are important in genetic studies. Approaches to take these challenges into account will be discussed. The concepts of imputing missing genotypes and haplotype inference will be explained. Replication and meta-analysis are commonly used in genetic epidemiological studies, and these concepts will be introduced. Finally, Mendelian randomization and the underlying assumptions will be explained.

Learning outcomes

After the course you will know
  • the basics of molecular genetics
  • the most important study designs for association analysis: case-control and cohort designs, designs for quantitative traits
  • the problems of population stratification and cryptic relatedness
  • the most important genetic marker types and their characteristics
  • the most important genotyping technologies, such as TaqMan for the analysis of few genetic markers, microarrays for genome-wide association studies and whole exome and whole genome sequencing studies
  • the quality control procedures and measures for the different genotyping technologies
  • how to conduct simple association analyses
  • how to estimate genetic effects
  • how to deal with multiple testing
  • the most important concepts for gene-based analyses using rare variants
  • how to biologically interpret genetic variants
  • Optional: how to calculate required sample sizes for association studies
  • Optional: haplotype-based analyses
  • Optional: the concept of Mendelian randomization studies
