Curly/woolly coat / Cornish Rex (LPAR6-related) - Cat

Cornish Rex and German Rex coat

This genetic test analyses the LPAR6 deletion c.250_253delTTTG, the recessive variant that causes the curly or woolly coat of the Cornish Rex and also occurs in the German Rex. LPAR6 is involved in normal hair development.

Affected cats have a fine, wavy to curly coat with few or no normal guard and awn hairs. The coat can be more fragile, making bald patches and sensitivity to cold more likely.

Practical value of this test

• Confirms whether the cat carries the Cornish Rex/German Rex coat variant.
• Helps breeders combine recessive carriers correctly.
• Clarifies whether a curly/woolly coat is genetically explained by LPAR6.

This coat variant is autosomal recessive: two copies cause the Cornish Rex/German Rex coat, while carriers can pass the variant on.
