Dominant Blue Eyes

Hypopigmentation of the hair, skin and eyes

Symptoms
One or two blue eyes or particolored eyes and minimal white spotting.
Homozygous and compound heterozygous cats are white or almost-white and not viable or with high risk of deafness.

Gene involved
PAX3

Mutation tested
g.206975776_206975777insN[433] (DBEALT)

Transmission mode : Autosomal dominant
Age of onset : From birth
Specificity : Heterozygous state of this allele does not appear to be associated with deafness. Homozygous cats are viable but are at high risk of deafness.
