G locus / white gloves (KIT-related) - Birman cat

G locus / white gloves in cats

This DNA test assesses the KIT variant c.1035_1036delinsCA that causes the white gloves of the Birman cat. The trait is also known as white socks, gloves, gloving and G locus. Cats with two copies show the typical sharply defined white feet, while one copy usually does not produce classic Birman gloving.

The white marking is part of the Birman breed standard and is mainly seen as symmetrical white feet. Because coat colour and white markings can be influenced by several loci, this test specifically describes the KIT variant for this G-locus trait.

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.
