We used structural equation modeling to decompose the contributions of direct fetal and indirect maternal genetic effects, then applied Mendelian randomization to illuminate causal pathways. For example, both indirect maternal and direct fetal genetic effects drive the observational relationship between lower birth weight and higher later blood pressure: maternal blood pressure-raising alleles reduce offspring birth weight, but only direct fetal effects of these alleles, once inherited, increase later offspring blood pressure. Using maternal birth weight-lowering genotypes to proxy for an adverse intrauterine environment provided no evidence that it causally raises offspring blood pressure, indicating that the inverse birth weight-blood pressure association is attributable to genetic effects, and not to intrauterine programming.]]> Wed 22 Mar 2023 15:25:15 AEDT ]]> Genome-wide association study identifies 74 loci associated with educational attainment https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33716 Wed 12 Dec 2018 14:03:45 AEDT ]]> Genetic effects on the timing of parturition and links to fetal birth weight https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52463 Wed 11 Oct 2023 15:07:44 AEDT ]]> Variants in the fetal genome near pro-inflammatory cytokine genes on 2q13 associate with gestational duration https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45201 P = 3.96 x 10-14). Analysis of 15,588 mother-child pairs shows that the association is driven by fetal rather than maternal genotype. Functional experiments show that the lead SNP, rs7594852, alters the binding of the HIC1 transcriptional repressor. Genes at the locus include several interleukin 1 family members with roles in pro-inflammatory pathways that are central to the process of parturition. Further understanding of the underlying mechanisms will be of great public health importance, since giving birth either before or after the window of term gestation is associated with increased morbidity and mortality.]]> Thu 27 Oct 2022 15:06:39 AEDT ]]>
