Other ectopic mineralization disorders such as diffuse idiopathic skeletal hyperostosis (DISH), caused by a lack of equilibrative nucleoside transporter 1 (ENT1), is characterized by increased ectopic mineralization of AF tissue and bone mineral density which progresses with age (Warraich et al., 2013; Fournier et al., 2020). The gene discussed is SLC29A1; the disease is atrial fibrillation.
