A compound attribute that is the ratio of amount of dual specificity mitogen-activated protein kinase kinase 6 (human) in blood to amount of sterile alpha motif domain-containing protein 9-like (human) in blood. The trait is MAP2K6/SAMD9L protein level ratio in blood (OBA_2053833, an Ontology of Biological Attributes id). Also known as: the ratio of amount of dual specificity mitogen-activated protein kinase kinase 6 (human) in blood to amount of sterile alpha motif domain-containing protein 9-like (human) in blood.
