Curly coat / Selkirk Rex (KRT71-related) - Cat

Selkirk Rex curly coat

This genetic test analyses the KRT71 variant c.445-1G>C, also known in the Selkirk Rex breed as SADRE, SLK or Re^S. KRT71 encodes keratin 71, a protein important for coat formation and structure.

The Selkirk Rex variant causes a dense, woolly, curly or tousled coat. One copy already gives a curly coat; cats with two copies can show a stronger or differently presented curl and body type.

Practical value of this test

• Confirms whether the cat carries the Selkirk Rex curly coat variant.
• Helps breeders plan expected coat type and the chance of curly kittens.
• Distinguishes clear, one-copy and two-copy Re^S results.

The Selkirk Rex variant is autosomal incomplete dominant: one copy is visible, while two copies can further influence curl expression.
