A compound attribute that is the ratio of amount of B-cell scaffold protein with ankyrin repeats (human) in blood to amount of Golgi-associated PDZ and coiled-coil motif-containing protein (human) in blood. The trait is BANK1/GOPC protein level ratio in blood (OBA_2053575, an Ontology of Biological Attributes identifier). Also known as: the ratio of amount of B-cell scaffold protein with ankyrin repeats (human) in blood to amount of Golgi-associated PDZ and coiled-coil motif-containing protein (human) in blood.
