Synteny conservation in the barhl locus. (A) Chromosomal regions carrying barhl in human, zebrafish and medaka were compared and neighbouring genes with conserved synteny identified. Each gene is represented in a different colour as an arrow showing its orientation on the chromosome. Neighbouring genes that are in synteny are shown with a schematic indication of their distance; which is not in scale. Exact location and full name of each gene can be found in the Additional file 1:Table 1. (B) Comparison of gene distribution in the ten loci for four teleost species and human. Syntenic genes are found either in the barhl1 group or the barhl2 group.
