OMA (Orthologous MAtrix) is a database of orthologs extracted from available complete genomes.[1]

The orthology predictions of OMA are available in several forms:

  • OMA Pairs: for a given gene, a list of predicted orthologs in other species is provided.
  • OMA Groups: a set of genes across different species which are all orthologous.
  • OMA Hierarchical Groups: the set of all genes that have evolved from a single ancestral gene in a given taxonomic range.
  • OMA Genome Pair view: the list of all predicted orthologs between two species.
