Gene variant affects omega three supplement needs in pregnancy

Researchers analyzed genetic data from the ADORE randomized trial to evaluate how a specific gene polymorphism influences docosahexaenoic acid dosing during pregnancy. PLOS Medicine reported that researchers Yan Ning Li, Kumar S. D. Kothapalli, Susan E. Carlson, Byron J. Gajewski, Emily A. DeFranco, and J. Thomas Brenna led the study. The investigation examined whether different genotypes of the FADS Indel polymorphism affect birth timing when pregnant women receive low or high doses of docosahexaenoic acid. [1]

The research focused on spontaneous early preterm birth, which occurs before 34 weeks of gestation. According to PLOS Medicine, early preterm birth is a major cause of newborn morbidity and mortality. The report noted that risk depends on ancestry, while current preventive measures remain limited.

The insertion allele of the FADS Indel polymorphism, known as rs66698963, modulates FADS1 gene expression. PLOS Medicine reported that this genetic variant increases the synthesis of arachidonic acid. This biological process enhances prosta compounds that promote labor. [1]

In genetics, observable characteristics or traits of an organism form its phenotype. The term encompasses developmental processes, biochemical properties, physiological features, morphology, and behavior beyond the genome itself. [2]
