Curly Coat (Coat type Dog)
Curly Coat refers to the length and texture of the hair. The dog has wavy to curly coat. Two causative mutations have been found for this coat structure. The genotype of the dog, i.e. which coat structure it will show, can be determined by a genetic test (KRT71 gene).

General Information
- Curly Coat refers to the length and texture of the hair.
- The dog has wavy to curly coat.
- Two mutations have been found for this coat structure:
- one in the Portuguese Water Dog
- one in the breeds Bichon Frise, Chesapeake Bay Retriever, Curly-coated retriever, Irish Terrier, Lagotto Romagnolo and Spanish Water Dog.
- Other breeds may also show this phenotype.
- A condition for the development of curly coat is the given disposition for long hair.
- In some breeds this trait is preferred, in others it is a requirement.
Test Information
This test detects two mutations (c.451C>T and c.1266_1273delinsACA) in the KRT71 gene.

Genotype and Lab Report
Inheritance: incomplete autosomal dominant.
→ Animals with one or two copies of the gene (n/Curly, Curly/Curly) show the phenotype Curly coat. Animals with no copy of the gene have a "normal" coat.
Genotypes:
n/n = two copies normal
No variants for curly coat, the dog has a "normal" coat.
n/Curly = One copy mutant and one copy normal.
The dog shows the coat structure Curly coat and passes it on to 50% of its offspring.
Curly/Curly = Two copies mutated
The dog shows the coat structure Curly coat and passes it on to 100% of its offspring.
Appearance
Curly coat
The dogs show wavy to curly coat.
The coat texture occurs in many breeds e.g. Portuguese Water Dog, Bichon Frise, Chesapeake Bay Retriever, Curly-coated retriever, Irish Terrier, Lagotto Romagnolo, Spanish Water Dog and others.
Possible genotypes:
n/Curly
Curly/Curly
