Current controversies in prenatal diagnosis 2: prediction and prevention of adverse pregnancy outcomes requires a genomic rather than proteomic solution.

Abstract：

:From both presentations, it is clear that understanding the APO associated with placental dysfunction represents one of the greatest challenges in the field of prenatal screening, diagnosis, and therapy. Their clinical impact on the health of the mother and child was well recognized by the debaters, and both have agreed that there is a paucity of knowledge in the etiophysiopathology of placental dysfunction and the associated clinical phenotypes. They also agreed that this marked limitation in our understanding is a significant problem when designing a research protocol, and both stressed the importance of proper study designs. When focusing on the specific topics of the debate, they showed different opinions about the role of genomics in the search for relevant answers. Leslie Myatt pointed out that the genome does not define the cellular phenotype, and although the proteome itself does not define phenotype, it is much closer to it than the genome. Conversely, Rossa Chiu suggested that genomic approaches offer a better chance of achieving the answers than by proteomics alone. Actually, she hypothesized that through genomic approaches, or rather through systems biology, that is, including genomics, epigenomics, transcriptomics, and proteomics, there would be a better chance of obtaining the best answers. She also raised the possibility of the potential use of cell-free fetal nucleic acids in maternal plasma, which in turn are mainly of placental origin. Finally, both debaters and the audience agreed that there was not an exclusive proteomic or genomic 'solution', but that we need a larger spectrum of research strategies to include both proteomics and genomics and other systems biology approaches, combined with detailed and standardized clinical, laboratory, and epidemiological criteria in appropriately designed studies in order to start filling the significant gaps in our knowledge about this highly complex area of placental mediated adverse pregnancy outcomes.
