Preeclampsia runs in families and it is now clearly established that like many other common human diseases there is a large genetic involvement in the risk of developing preeclampsia. However, the genetics are complex and not yet fully elucidated. The identification of genetic risk variation for common complex diseases is a current high priority for the provision of personalised medicine and genetic analysis of preeclampsia therefore continues to be a critically important focus of research effort in obstetric medicine.

In 2000, Prof Eric Moses along with Prof Shaun Brennecke and their multidisciplinary research team based at the Royal Womens Hospital in Melbourne published a seminal genome wide linkage scan for preeclampsia in a cohort of Australian and New Zealand preeclampsia families. On the strength of this family study Moses and Brennecke and acclaimed USA statistical geneticist John Blangero obtained funding from the NIH to identify the risk genes that the linkage evidence obtained in these families pointed to. In a major international collaboration that also included investigators in Norway the team identified the activin receptor gene ACVR2A and the endoplasmic reticulum aminopeptidase 2 gene ERAP2 as preeclampsia susceptibility genes.

There remains however missing heritability for preeclampsia and Prof Moses and his collaborators are continuing the search for susceptibility genes now taking full advantage of recent advances in genomic analysis, including whole genome sequencing, transcriptomics and methylomics.

This work is a collaboration between researchers at UWA, Curtin University, University of Texas Rio Grande Valley (UTRGV), the Royal Women’s Hospital in Melbourne, the Norwegian University of Science and Technology and the University of Helsinki.
