A compound attribute that is the ratio of amount of proheparin-binding EGF-like growth factor (human) in blood to amount of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 2 (human) in blood. The trait is HBEGF/PFKFB2 protein level ratio in blood (OBA_2053004). Also known as: the ratio of amount of proheparin-binding EGF-like growth factor (human) in blood to amount of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 2 (human) in blood.
