Welcome to OMIA

 

Online Mendelian Inheritance in Animals (OMIA) is a catalogue/compendium of inherited disorders, other (single-locus) traits, and associated genes and variants in 529 animal species (other than human and mouse and rats and zebrafish and western clawed frog, which have their own resources) co-authored by curator Associate Professor Imke Tammen and founder 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, to OMIM, Ensembl, Mondo Disease Ontology and the Vertebrate Breed Ontology (VBO).

OMIA is manually curated by a team of specialists. If you see an error or wish to submit an entry, please contact us.

From 1st September 2011, the OMIA ID is binomial. To better conform to global standards, in March 2023 the binomial format was changed slightly by replacing a space with a colon, i.e. OMIA:xxxxxx-yyyy.., where xxxxxx is the 6-digit number for a trait/disorder, and yyyy.. is the NCBI species taxonomy id (usually four digits, but sometimes longer).

We have recently launched the Pioneers of Mendelian Inheritance in Animals project (PMIA), an exploration of the history of research into Mendelian inheritance in animals.
