Starting as a mainframe database in 1980 called Mendelian Inheritance in Animals (MIA), the online version (OMIA) was launched as an open-access web-based resource on 26 May 1995. This was a few months before the University's first official website was launched in October 1995.
Twenty-five years later, OMIA continues to provide researchers, veterinarians and breeders from more than 150 countries with up-to-date summary information on all the known harmful and beneficial mutations in animals, together with background information on all known inherited disorders and beneficial traits, including those for which causal mutations have not yet been discovered.
OMIA covers more than 3,500 traits from achondroplasia to yellow-semen syndrome, across more than 250 species from agile gibbon to zebra finch. There are even two entries for woolly mammoth! (based on DNA analysis of preserved bone fragments). The vast majority of OMIA entries are for the major domesticated animals, such as dogs, cats, horses, cattle, sheep, pigs, chickens and goats. The only animals not included are species such as mice and rats, which have their own databases.
