报告题目: Applications of Set-Valued Models in Disease Gene Mapping

报告人: Guolian Kang, Associate Member

    Department of Biostatistics, St. Jude Children’s Research Hospital

Abstract: Genome-wide association studies (GWAS) have been successful in the last decades to identify common variants (CVs) associated with common or rare diseases. With availability of next generation sequencing (NGS) data, it becomes possible to identify rare variants (RVs) associated with common or rare diseases too in the last several years. Commonly used statistical methods for the identification of CVs do not work well to identify RVs. The set-valued (SV) system widely exists. The corresponding set-valued system identification was investigated and used successfully in various field such as sensor system, sensor networks, telecommunications, etc. In this talk, I will present how to apply SV idea to the frontline research of causal gene mapping in GWAS and NGS. I will first discuss the application of SV idea to the primary binary outcome in a case-control design, followed by primary ordinal outcomes. Then the generalization of these results to the secondary binary and continuous phenotype analysis in a case-control design will be presented, followed by secondary phenotype analyses in an extreme phenotype sequencing design. Real large-scale GWAS or NGS data will also be analyzed for each topic above to show the performance of the new proposed SV methods compared to its alternatives. At last, the future interesting ongoing research topics will be discussed.
