New Research Illuminates How The Genomes Of Mothers And Children Impact Pregnancy Length

“In samples, we were able to identify numerous previously undiscovered genetic variants associated with the timing of parturition, and these provide unmatched insights into the underlying biological mechanisms,” Jacobsson noted.

And interestingly, the researchers found that there may be a conflict between mothers’ and children’s genomes in terms of gestational duration.

“Genetically, the woman’s genes favor the earlier onset of labor to expel the child, for her own survival, while those of the unborn child favor extension of the pregnancy to gain weight. So, they reach a kind of compromise deal,” explained Pol Solé Navais, the study’s first author.

So, moving forward, the research could serve two major purposes: aiding the development of drugs that prevent preterm birth and boosting or mitigating contractions during delivery.
