|Mode of Inheritance|
X-Linked Retinal Dysplasia is a severe disorder of the eye observed in the English Cocker Spaniel, causing retinal detachment and cataracts. As an X-linked recessive disorder, it is carried by females and passed down to affect males. The disorder is caused by an X-linked recessive mutation to the gene NDP. As such, it is primarily expressed in males.
Affected puppies present with the behavioral symptoms of severe visual impairment. Their pupils do not react to light, and they present with darkened irises, retinal bleeding and sometimes cataracts. Cryptorchidism (absence of at least one testicle in the scrotum) may also be linked to the disorder.
