Figure 1.

The LEUTX homeobox gene (orange arrow) plus four unusual non-homeobox genes (light grey arrows) form a linked set of genes in the human genome (dashed box). Divergent putative Leutx genes are located in syntenic regions of cow, dog and elephant (orange arrows), but absent at the equivalent location in mouse and rat. Non-homeobox genes used as indicators of chromosomal synteny are shown as grey arrows.
