What’s so Special About Orange Cats? Turns Out They’re Freaks of Nature | News Channel 3-12
- Scientists identified a specific DNA deletion mutation causing the orange fur color in domestic cats in a study published May 15 in Current Biology.
- Researchers found this unusual mutation only in domestic cats and not in wild cats or other animals, suggesting it arose once during domestication and was selectively bred for.
- The mutation involves a 5,076-base-pair deletion on the X chromosome that activates the gene Arhgap36, which blocks black pigment and shifts pigment production to orange pheomelanin.
- Lead author Christopher Kaelin called it "a really unusual type of mutation" and noted the findings could provide new insights into genetic mechanisms and feline evolution.
- The discovery offers tools to trace domestic cat evolution and raises questions about similar mutational mechanisms in other genes and species.

What's so Special About Orange Cats? Scientists Have Discovered They're Nature Freaks.
By Amanda Schupak, CNN A new study may have discovered what's so special about orange cats, though it might not be what you think. Ginger cats are known among cat owners for being particularly friendly and energetic. However, for geneticists, the uniqueness of these domestic cats lies in the unusual way they acquire their color. Now, scientists say they have unraveled a long-standing mystery by identifying the specific DNA mutation responsible f…
Scientists Solve Mystery of Ginger Cats; Implications for All Cells and Tissues - WhoWhatWhy
Scientists Solve Mystery of Ginger Cats; Implications for ‘All Cells and Tissues’ (Maria) The author writes, “After decades of mystery, new research has shed light on a question that has long stumped scientists and cat lovers alike — what exactly makes cats orange? Two studies published in Current Biology last week by separate teams at Stanford University and Japan’s Kyushu University at last provided some answers. Scientists have known for more…
