Title: Association Testing Based On Sequencing Data With Arbitrary Depth

Abstract: Association studies have been widely conducted to explain the relationship between phenotypes and genetic variants. Researchers have been developed association testing methods for a single marker or a group of markers based on genotypes. The phenotypes, either continuous or binary traits, are studied in the regression framework with genotypes as explanatory variables. Some factors such as genotype calling uncertainty and sequencing depth may influence the performance of these genotype-based testing methods. We propose association testing methods directly based on next-generation sequencing data without genotype calling. The methods have been applied to the testing for a single marker or a group of markers with applications to rare variants.

We look forward to seeing you all among us.
