A compound attribute that is the ratio of amount of a disintegrin and metalloproteinase with thrombospondin motifs 15 (human) in blood to amount of sulfotransferase 2A1 (human) in blood. The trait is ADAMTS15/SULT2A1 protein level ratio in blood (OBA_2053736). Also known as: the ratio of amount of a disintegrin and metalloproteinase with thrombospondin motifs 15 (human) in blood to amount of sulfotransferase 2A1 (human) in blood.
