Overview on pipeline results for vertebrate Hox clusters. SynBlast results and manually extracted orthologous cluster positions and identities for selected vertebrate species are listed. Unless otherwise indicated, positions correspond to assigned blast hits' intervals from Hox1 to Hox13/Evx hits in gene order alignment. Cluster orientation is w.r.t. the human reference clusters, which are HOXA9_ENSG00000078399_5e5; HOXB9_ENSG00000170689_2e5; HOXC9_ENSG00000180806_3e5; HOXD9_ENSG00000128709_5e5. Unassigned loci from the reference may be due to overlaps of chained HSPs. A '*' indicates loci that are absent in agreement with the literature . Data for Ensembl release 42 (Dec 2006).
