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 ]]> Genetic effects on the timing of parturition and links to fetal birth weight https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52463 Wed 11 Oct 2023 15:07:44 AEDT ]]> Genome-wide association study of placental weight identifies distinct and shared genetic influences between placental and fetal growth. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53968 Tue 23 Jan 2024 15:33:56 AEDT ]]>
