Interestingly, expression profiling using a 12‐gene assay reliably distinguished metastasising from non‐metastasising uveal melanomas in humans [138] and four of these genes (HTR2B, FXR1, LTA4H, and CDH1) are overexpressed in metastasising canine uveal melanoma [139]. Here, FXR1 is linked to uveal melanoma.
