Human paralogons of the FOX cluster loci. A schematic representation of paralogy deduced from analysis of the human genome using NCBI map viewer Hs Build 36.1 (Nov 01, 2005) . Gene names are shown above each gene, while numbers in the boxes indicate subfamily. Letters on the far left indicate paralogon designation, while numbers on the far right indicate which chromosome the cluster is found on. Numbers between genes are approximate intergenic distances in Kb. Background shading indicates paralogy.
