Overview

What does this test examine?

This genetic analysis examines five variants in the FGF5 gene used for hair length, long coat and, in some breeds, fluffy coat in dogs. The subanalyses cover FGF5 c.284G>T, c.578C>T, c.559_560dupGG, c.556_571del and c.368-11T>A.

What does it mean for the dog?

FGF5 helps regulate the growth phase of the hair follicle. Variants that reduce normal FGF5 function can allow hair to keep growing for longer. In many dogs, long hair behaves recessively: a dog with one long-hair allele is usually a carrier, while two long-hair alleles, either identical or combined across different FGF5 variants, can produce a longer coat. Other coat genes still shape texture, colour, curl, furnishings and the final look.

Practical value of this test

  • Breeders can identify dogs carrying long-hair alleles, even when the dog itself has a short coat.
  • The result helps predict which matings can produce long-coated puppies and which combinations are expected to produce mostly short-coated puppies.
  • In breeds where long coat, fluffy coat or coat length is commercially and reproductively important, the panel gives more certainty than appearance alone.

Because five variants are tested, the result should be read across all subanalyses together. Two relevant FGF5 variant copies can produce a long-coat outcome, even when the copies are found in two different subanalyses.

Included subanalyses

This analysis includes the following subanalyses:

  • Hair length 1 / long coat 1 (FGF5 c.284G>T) - Dog
  • Hair length 2 / long coat 2 (FGF5 c.578C>T) - Dog
  • Hair length 3 / long coat 3 (FGF5 c.559_560dupGG) - Dog
  • Hair length 4 / long coat 4 (FGF5 c.556_571del) - Dog
  • Hair length 5 / long coat 5 (FGF5 c.368-11T>A) - Dog
