A compound attribute that is the ratio of amount of protein disulfide isomerase CRELD2 (human) in blood to amount of thioredoxin domain-containing protein 5 (human) in blood. The trait is CRELD2/TXNDC5 protein level ratio in blood (OBA_2054491). Also known as: the ratio of amount of protein disulfide isomerase CRELD2 (human) in blood to amount of thioredoxin domain-containing protein 5 (human) in blood.
