CommentIt is not clear either from phylogenetic or syntenic information how many Mir-2 genes were present in the last common ancestor of protostomes and how the multiple paralogues in lophotrochozoans relate to the four Mir-2 genes in arthropods. Thus all lophotrochozoan genes aside from Mir-2-P12 are classified as orphans pending further data and analysis.
