  • ~ Online Mendelian Inheritance in Animals ~

      Online Mendelian Inheritance in Animals (OMIA) is an online database, freely available to anyone in the world, created and curated in the Sydney School of Veterinary Science, within the University of Sydney, by Emeritus Professor Frank Nicholas, assisted by local and international colleagues.


      Brief Bio: Online Mendelian Inheritance in Animals (OMIA) is a catalogue/compendium of inherited disorders, other (single-locus) traits, and genes in 253 animal species (other than human and mouse and rats, which have their own resources) authored by Professor Frank Nicholas of the University of Sydney, Australia, with help from many people over the years. OMIA information is stored in a database that contains textual information and references, as well as links to relevant PubMed and Gene records at the NCBI, and to OMIM and Ensembl.

      About Us:

      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.
