CLINICAL MEASUREMENT - ANNOTATIONS

The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87. Epub 2012 May 28 or contact us (http://rgd.mcw.edu/contact/index.shtml).

Definition:A calculated measurement in which the value representing the two-dimensional extent of the planar region of the dorsal half of the body surface occupied by hair, wool, or fur (cylindrical, keratinized, often pigmented filaments characteristically growing from the epidermis of a mammal) containing proteins or other substances which give that hair the appearance of color, is divided by the value representing the entirety of the two-dimensional extent of the planar region of the dorsal half of the body surface of the organism occupied by hair, wool, or fur with or without color, and presented as a ratio, fraction, quotient or percentage. The dorsal half of the body is the approximately fifty percent of the body closest to the back and, in vertebrates, containing the spine. Color is property of a surface or substance due to absorption of certain light rays and reflection of others within the range of wavelengths (roughly 370-760 nm) adequate to excite the retinal receptors.
