Synteny between regions containing STAT4 and STAT1 genes on human chromosome 2 and Danio rerio chromosomes 22 and 9. Genes transcribed on the top or bottom strands are shown above and below the lines representing the chromosomes. Homologous regions are shown by colored arrows. A further duplication of the region containing HIBCH and GDF8 is found on Danio rerio chromosome 11. Numbers represent nucleotide positions in the genome in megabases based on the Zv6 assembly. Gene names are Swissprot, Zebrafish Information Network, or Ensembl identifiers.
