Metaphyseal Enchondromatosis with D-2-Hydroxyglutaric Aciduria, also known as metaphyseal chondromatosis with d-2-hydroxyglutaric aciduria, is related to leukemia, acute myeloid and organic acidemia. An important gene associated with Metaphyseal Enchondromatosis with D-2-Hydroxyglutaric Aciduria is IDH1 (Isocitrate Dehydrogenase (NADP(+)) 1). Affiliated tissues include bone and globus pallidus, and related phenotypes are d-2-hydroxyglutaric aciduria and multiple enchondromatosis
