I want to follow up some GWAS hits for obesity by doing some eQTL analysis in fat and liver tissue. I found this paper by Eric Schadt's group that did something similar, and I found their expression data on ArrayExpress, and on GEO here, here, and here.
Assuming this study was funded by NIH they are required to deposit their data onto dbGaP. Given a publication and an author list, how can I search dbGaP to see if the data mentioned in this paper is in dbGaP? It seems that you need to know the title of the study to find a dataset, and knowing a paper or author list doesn't help you much. Any help is appreciated.
