A compound attribute that is the ratio of amount of beta-1,4-galactosyltransferase 1 (human) in blood to amount of SPARC-related modular calcium-binding protein 2 (human) in blood. The trait is B4GALT1/SMOC2 protein level ratio in blood (OBA_2053551). Also known as: the ratio of amount of beta-1,4-galactosyltransferase 1 (human) in blood to amount of SPARC-related modular calcium-binding protein 2 (human) in blood.
