SLC7A7 and fetal growth restriction: Consistent with previous reports (Stroup et al., 2020; Sperandeo et al., 2007), we observed significant reductions in the body weights of Slc7a7Lbu/Lbu embryos compared to those of WT embryos at embryonic day (E)17.5, indicating IUGR with global Slc7a7 deficiency (Fig. 2A).
