摘要: Abstract Despite the indispensable role of placenta in successful course pregnancy, regulation its dynamic transcriptome is still underexplored. The purpose this literature review was to give an overview and draw attention contribution genetic variation shaping human placental gene expression. Studies shaped by chromosomal variants are limited may be confounded cellular mosaicism somatic genomic rearrangements. Even relatively simple cases, such as aneuploidies, appears differ from assumed systematically increased transcript levels involved chromosomes. Single nucleotide modulating expression referred quantitative trait loci (eQTLs) have been analyzed only ten candidate three genome-wide association studies (GWAS). latter identified 417 confident eGenes, supported at least two independent studies. Functional profiling eGenes highlighted biological pathways important immune response or transmembrane transport activity. A fraction eQTLs (1–3%) co-localize with GWAS for adult disorders (metabolic, immunological, neurological), suggesting a co-contributory developmental programming health. Some risk factors adverse pregnancy outcomes, rs4769613 (C > T), located near FLT1 confidently associated preeclampsia. More needed map different cell types across trimesters normal complicated gestations clarify what extent these heritable contribute maternal offspring disease risks.
