The Effect of Maternal Fatty Acid Desaturase Single Nucleotide Polymorphism rs174602 and Prenatal Supplementation with Docosahexaenoic Acid on the Offspring Metabolome

ABSTRACT: Abstract

Objectives

To assess if maternal fatty acid desaturase (FADS) single nucleotide polymorphism (SNP) rs174602 modifies the effect of prenatal DHA supplementation on the offspring metabolome at age 3 months.

Methods

Data were obtained from POSGRAD, a double-blind randomized controlled trial in Mexico in which 1094 women received 400 mg/day of algal DHA or a placebo (corn and soy oil) from mid-gestation until delivery. Genotyping was performed using maternal blood samples collected from women at baseline. Using liquid chromatography with high-resolution mass spectrometry, untargeted metabolomics was performed on plasma samples obtained from a random subsample of 112 offspring of POSGRAD participants at 3 months of age. Discriminatory metabolic features were selected
