A compound attribute that is the ratio of amount of alanyl-tRNA editing protein Aarsd1 (human) in blood to amount of protein-glutamine gamma-glutamyltransferase 2 (human) in blood. The trait is AARSD1/TGM2 protein level ratio in blood (OBA_2053725). Also known as: the ratio of amount of alanyl-tRNA editing protein Aarsd1 (human) in blood to amount of protein-glutamine gamma-glutamyltransferase 2 (human) in blood.
