Homeobox genes are involved in body plan formation and in the regulation of many developmental processes in
bilateria. For this reason, the evolutionary history of Hox, ParaFlox, EHGbox, and NK homeobox gene families could be crucial to understand the evolution of molluscan body plans and phylogeny.

They found that SYCE2 and TEX12 are conserved in Metazoa, SYCE1 appears in
Bilateria, and SYCE3 is specific for Vertebrata.
While whole-genome sequencing data have been available for four of the five major animal lineages - sponges (Porifera), flat invertebrates (Placozoa), jellyfish (Cnidaria), and animals with left-right symmetry, including humans (
Bilateria) -Ctenophora remained the last major animal lineage for which there were no sequenced genomes.
