About Online Mendelian Inhertance in Animals

Online Mendelian Inheritance in Animals (OMIA) is a database of the genes and phenes* that have been documented in a wide range of animal species other than those for which databases already exist (human, rat and mouse). It is modelled on, and is complementary to, McKusick's Mendelian Inheritance in Man (MIM).

OMIA has been under construction since 1980. It contains references to publications on any trait or disorder for which familial inheritance has been claimed, except for a gap for the years 1982-88, which is gradually being filled. It does not contain sequence data. Each reference has been indexed to one or more phenes and/or genes, and to species. At present, an entry consists solely of references arranged chronologically for each phene in each species. Over the next few months, gene information will also be included and textual material will begin to appear, providing synonyms for phenes, summaries of current knowledge, clinical and diagnostic features and cross-references to other knowledgebases.

The compilers are aware of many inadequacies in the material presently available, but believe that it is still useful. Constructive suggestions for improvements will always be gratefully received.


* A phene is a word or words that identify a familial trait. For single-locus traits, the word(s) correspond to one of the phenotypes that arise from segregation at that locus. For example, CITRULLINAEMIA is the phene for the ARGININOSUCCINATE SYNTHETASE locus; and FECUNDITY, BOOROOLA is the phene for a locus that has not yet been identified at the biochemical/molecular level. OMIA also includes multifactorial traits and disorders. Thus, for example, HIP DYSPLASIA is a phene.
