Claims
Breed: Basenji (Dog)Disorder:Mode of inheritance: Autosomal recessive- `Clin feat: While there are multiple types of progressive retinal atrophy (PRA), Basenjis generally obtain late onset PRA (Goldstein et al., 2013). Initially, affected individuals lose their vision in dim light and lose their peripheral visual field, resulting in tunnel vision. Many individuals can maintain forward day vision for years as disease progresses (Goldstein et al., 2013). Retinal thinning (stage I) can typically be detected at five years old, and reduced blood flow through retinal vasculature (stage II) is normally detected around seven years of age (Goldstein et al., 2013).
