(OMIA)](http://www.http://omia.angis.org.au),
from which we process inherited disorders, other (single-locus) traits,
and genes in >200 animal species (other than human and mouse and rats).
We generate the omia graph to include the following information:
* genes
* animal taxonomy, and breeds as instances of those taxa
(breeds are akin to "strains" in other taxa)
* animal diseases, along with species-specific subtypes of those diseases
* publications (and their mapping to PMIDs, if available)
* gene-to-phenotype associations (via an anonymous variant-locus
* breed-to-phenotype associations
We make links between OMIA and OMIM in two ways:
1. mappings between OMIA and OMIM are created as OMIA --> hasdbXref OMIM
2. mappings between a breed and OMIA disease are created
to be a model for the mapped OMIM disease,
IF AND ONLY IF it is a 1:1 mapping.
there are some 1:many mappings,
and these often happen if the OMIM item is a gene.
Because many of these species are not covered in
the PANTHER orthology datafiles, we also pull any orthology
relationships from the gene_group files from NCBI.
