Welcome to OMIA

Online Mendelian Inheritance in Animals (OMIA) is a catalogue/compendium of inherited disorders, other (single-locus) traits, and genes in 292 animal species (other than human and mouse and rats, which have their own resources) co-authored by Professor Frank Nicholas and Associate Professor Imke Tammen 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.

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, with the format 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).
