We have recently demonstrated in this model that maternal selenium deficiency induces fetal growth restriction (Hofstee et al., 2019), alters selenoprotein expression (Hofstee, Cuffe, et al., 2020), and perturbs an array of metabolic parameters in the mother and fetus (Hofstee et al., 2019) and in 6‐month offspring (Hofstee, McKeating, et al., 2020). This evidence concerns the gene SELENOS and selenium deficiency.
