The sex-linked orange mutation in domestic cats causes variegated patches of reddish/yellow hair and is a defining signature of random X inactivation in female tortoiseshell and calico cats; unlike the situation for most coat color genes, there is no apparent homolog for sex-linked orange in other mammals; Kaelin et al. show that sex-linked orange is caused by a 5-kb deletion that leads to ectopic and melanocyte-specific expression of the Arhgap36 gene. Image credit: Kaelin et al., doi: 10.1016/j.cub.2025.04.055.
