Equus in Online Mendelian Inheritance in Animals (OMIA).

Online Mendelian Inheritance in Animals (OMIA is a freely available information resource, which includes information for Equus inherited traits/diseases (collectively called phenes). The database focuses on Mendelian traits and their likely causal variants (mutations). Some of these Mendelian traits are favored by humans, e.g., coat color, while others are diseases. Additions to OMIA are based on publications of peer-reviewed research. Maintaining up-to-date information in OMIA is a challenge, owing to the multiplicity of species, the increase in the number of relevant publications, and as reference genomes and methods of citation continue to evolve. This challenge has been successfully aided by contributions from scientists from around the world. In some cases, those scientists are faculty members who charge their students with curation as an educational activity. Recently, OMIA has introduced computerized lists of standardized names and synonyms (called ontologies) for breeds of Equus and other animals and for phene categories. These ontologies facilitate increased connectivity between OMIA and other online resources. OMIA is and will continue to be a major reference resource for Mendelian phenes in the genus Equus.
