Table 1. Overview of the steps in the study design.

Step no. Analyses Sample type Study population
1 Identification of differentially expressed genes in PE Transcription profiling data from decidual basalis Norwegian PE and non-PE women
2 Identify genes from step no. 1 that are expressed above background level in the SAFHS blood lymphocytes Transcription profiling data from blood lymphocytes San Antonio Family Heart Study
3 Investigate if the genes from step no. 2 are correlated with variation in lipid levels Transcription profiling data from blood lymphocytes San Antonio Family Heart Study
4 Identify SNPs that are genotyped in the top gene from step no. 3 Genome-wide SNP data San Antonio Family Heart Study
5 Test if the SNPs from step no. 4 are associated with variation in lipid levels Lipid levels and SNPs San Antonio Family Heart Study
6 Test if the SNPs from step no. 4 are associated with transcription level of the gene (cis-regulation) Transcription profiling data (blood lymphocytes) and SNPs San Antonio Family Heart Study
