Abstract

DESCRIPTION (provided by applicant): One of the central problems in modern human genetics is to understand the functional impact of genetic variation. Of the millions of DNA positions that vary among humans, which sites actually impact human phenotypes and disease? It is becoming increasingly clear that noncoding variants that impact gene regulation play central roles in the genetics of disease. Yet we have limited understanding of the precise pathways by which these variants act, and it remains extremely difficult to predict which variants in the genome have regulatory effects. In this projec we propose to use detailed functional characterization of a variety of aspects of gene regulation, using 70 human lymphoblastoid cell lines as a model system, along with new computational methods, to dissect in detail the mechanisms by which genetic variation impacts gene expression levels.
