Trait overview

The genetic variations resulting in curly fur are called rex mutations. They can occur in a variety of genes, such as KRT71, LIPH and LPAR6, thus creating various types of curly coats in cats. These mutations cause changes in the hair structure, leading to the curly appearance.

Gene name(s)

KRT71 (Selkirk rex, Devon rex), LIPH (Ural rex), LPAR6 (Cornish rex, German rex)

Inheritance

Autosomal incompletely dominant (KRT71-defined Selkirk rex coat); autosomal recessive (KRT71-defined Devon rex curly coat; LPAR6-defined Cornish rex and German rex coat; LIPH-defined Ural rex coat)

More common in the following breeds

, , , German rex, Ural rex
