Glitter coat (FGFR2-related) - Cat

Glitter coat in cats

This DNA test assesses a 585 bp insertion near FGFR2 that causes the glitter coat in cats. The trait is also known as glitter, glitter coat, iridescent sheen and sparkling coat. Glitter is not a standard colour mutation, but a structural hair morphology that reflects light differently and can produce a golden, pearly or crystal-like sheen.

The effect can range from a subtle sheen to a pronounced sparkling appearance. In breeds such as Bengal, Egyptian Mau and Toyger, the result helps confirm the genetic basis of this desired coat type.

How to read the result

• Clear: the tested variant is not detected.
• Carrier: the cat carries one copy and can pass the variant on.
• Two copies: the variant causes the described trait.

Practical value of this test

• confirms whether the cat is clear, carrier or genetically positive for this variant;
• helps combine or avoid a desired coat trait deliberately;
• supports selection without waiting for the adult coat to be fully visible.
