Darier Disease is a skin condition characterized by loss of cell-to-cell adhesion and abnormal keratinization that results in hairless, plaque-like lesions on the skin.
ATP2A2
Autosomal dominant
Dogs affected with Darier Disease often have crusted lesions, with possible ulceration. Ears are a common site for these lesions.
A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. Histology of the lesion will show acantholytic cells. Genetic testing is necessary to determine if there is an underlying genetic cause, which can assist veterinarians with diagnosis and help breeders identify affected and carrier dogs.
