SNAT2 has gained interest for its involvement in e.g. placental nutrient transport (Vaughan et al. 2021), alveolar fluid clearance (Weidenfeld et al. 2021), pancreatic function (Zhang et al. 2023), and cancers like gastric cancer and breast cancer (Morotti et al. 2021; Zhu et al. 2023). Here, SLC38A2 is linked to cancer.
