Description of intervention(s) / exposure
We will extract RNA from placenta samples to quantify gene expression using deep sequencing by RNA-seq and microarray platforms. This is a single time-point "snapshot" observation to generate the complete placental transcriptome in health and disease. A saliva sample from both mothers and fathers will also be collected in the antenatal clinic for genome-wide SNP genotyping to determine parent of origin allele expression in placentas

Outcomes
Primary outcome [1] 288316 0
Identification and expression level of all coding and non-coding RNA in placentas from normal pregnancies and those complicated by preeclampsia (PE) and intrauterine growth restriction (IUGR). We will sequence RNA using the Illumina Hi-Seq platform to generate the data and test the differences between normal and complicated pregnancies using established and custom designed bioinformatics pipelines.
