OMIA 001866-9685 : Hypotrichosis, Don Sphynx in Felis catus

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Incompletely Dominant

Considered a defect: yes

Key variant known: no

Species-specific name: Also known as Donskoy and Russian hairless

Inheritance: Zhigachev et al. (2000) reported autosomal incompletely dominant inheritance.

Molecular basis: In contrast to the situation with Canadian Sphynx cats, whose hairlessness is due to a mutation in KRT71 (see OMIA 001583-9685), Dierks et al. (2013) ruled out mutations in KRT71 as being causal for the hairlessness of Don Sphynx cats.

Breed: Don Sphynx.
