A compound attribute that is the ratio of amount of hypoxia up-regulated protein 1 (human) in blood to amount of inactive tyrosine-protein kinase transmembrane receptor ROR1 (human) in blood. The trait is HYOU1/ROR1 protein level ratio in blood (OBA_2052974). Also known as: the ratio of amount of hypoxia up-regulated protein 1 (human) in blood to amount of inactive tyrosine-protein kinase transmembrane receptor ROR1 (human) in blood.
