Fig. 2From: Protein–protein interaction network-based integration of GWAS and functional data for blood pressure regulation analysisThe relational scheme of the BP-GWAS meta-database. The scheme comprises two parts: the GWAS-related ontology part (bottom) and the SNP genotypic information part (top). The meta-database is connected to the RHCP-based genetic information ontology network of the PICKLE PPI meta-database at the transcript and gene levels, through SNP–transcript consequences and eQTL measurements, respectivelyBack to article page
