A compound attribute that is the ratio of amount of protein phosphatase 1 regulatory subunit 12A (human) in blood to amount of synaptosomal-associated protein 29 (human) in blood. The trait is PPP1R12A/SNAP29 protein level ratio in blood (OBA_2053497). Also known as: the ratio of amount of protein phosphatase 1 regulatory subunit 12A (human) in blood to amount of synaptosomal-associated protein 29 (human) in blood.
