MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.

Accession:MP:0009389 term browser browse the term
Definition:anomaly in the coloration of organs and tissues excluding the integument due to changes in the amount, shape, or distribution of cells producing pigment
Comment:Note that significant differences exist among populations of melanocytes that populate the cutaneous tissue compared to melanocytes that populate ocular, auditory, and internal body sites. Extracutaneous melanotcytes synthesize melanosomes and melanin only during a short interval after arriving in their target tissue, and they retain their melanosomes throughout the life of the organism instead of transferring to neighboring cells like dermal melanocytes. General morphology and ultrastructure of extracutaneous melanocytes vary and also differ from cutaneous melanocytes.
