Summary
This genome-wide association study investigated how parental and fetal genomes independently influence fetal growth, using Icelandic population data. The research distinguished between genetic effects transmitted through the maternal genome versus those acting through the fetal genome itself, contributing to understanding of the genetic architecture underlying intrauterine growth. The findings suggest that parental and fetal genetic contributions to fetal growth operate through distinct biological pathways.
Regional applicability
The findings from an Icelandic population may have limited direct application to UK clinical practice, though the methodological approach to partitioning parental versus fetal genetic effects could inform UK studies of maternal–fetal health. The results may be relevant to understanding genetic contributions to birth outcomes in populations of similar ancestry.
Key measures
Birth weight, fetal growth trajectories, genetic variants (SNPs), maternal and fetal genome-wide association signals
Outcomes reported
The study examined the distinct contributions of parental versus fetal genetic variants to fetal growth outcomes. It measured associations between genetic markers and birth weight and other fetal growth parameters.
