Even though none of these genes were related to regulation of BP by GO analysis, we observed four genes with at least twofold difference between HF vs. control in female: Agtr1b (fold change (FC) = 4.4) and Ace (FC = 0.3) in the RAS, Ddah1 (FC = 0.3) in the NO system, and Slc12a3 (FC = 0.3) belonging to sodium transporters. This evidence concerns the gene SLC12A3 and hydrops fetalis.
