Arterial Calcification of Infancy, also known as generalized arterial calcification of infancy, is related to calcification of joints and arteries and pseudoxanthoma elasticum. An important gene associated with Arterial Calcification of Infancy is ENPP1 (Ectonucleotide Pyrophosphatase/Phosphodiesterase 1), and among its related pathways/superpathways are Metabolism of proteins and Glucose / Energy Metabolism. The drugs Cholecalciferol and Calcitriol have been mentioned in the context of this disorder. Affiliated tissues include heart and skin, and related phenotypes are calcification of the aorta and hepatic calcification
