Informations générales

This variant of PRA, Progressive Retinal Atrophy type 3, occurs in the Tibetan Spaniel and Tibetan Terrier. It is associated with by a recessive mutation to the gene FAM161A.
Caractéristiques cliniques
Affected dogs generally show the first signs of night blindness between three and seven years of age. After the initial signs present, the disease can progress rapidly, often leading to complete loss of vision within one year. Opthalmological examination can reveal thinning of the retinas.
Additional Information
The mutation in this test is a risk factor, and has not yet been established as the sole cause of the disorder.
