Coat length - test of FGF5-gene variants in Akitas

In Akitas, there was found c.578C˃T FGF5 gene variant that causes long coat. In Akitas, long coat phenotype is visible in age of 3-4 weeks (Dierks et al. 2013).

Genomia tests 4 FGF5 gene variants (c.284G>T, c.556_571del16, c.559_560dupGG, c.578C>T (Diers et al. 2013)) that influence the length of coat. For further information about FGF5 gene variants continue...

Table of FGF5 gene variants (Dierks et al. 2013)

Gene variant FGF5

Protein variant


M1: c.284G>T


Many breeds

M2: g.8193T>A (Genomia does not test this variant)

Blocking of exonu 2 splicing

Afghan Hound

M3: c.556_571del16



M4: c.559_560dupGG


Afghan Hound, Eurasier

M5: c.578C>T


Akita, Siberian Husky, Samoyed

Long coat in Akitas in inherited in autosomal recessive trait.


Possible results in M5 gene variant:

  • N/N – the dog does not carry any variant specific for long hair – the dog has short hair
  • N/M5 – the dog carries one copy of the variant gene – the dog is short-haired, but it can give birth to long-haired offsprings, if suitably crossed.
  • M5/M5 – the dog is long-haired
