The progressive retinal athrophy (PRA) is an inherited eye disorder leading to a degeneration of the photoreceptor cells of the retina. Initially,a loss of function of the rod cells is observed proceeding in night blindness and decreased adaptation of vision. The PRA form in Papillons and Phalènes show a wide range in age of onset maybe due to different genetic background or environmental influences. The known genetic variant explains about 70% of PRA affected dogs. So, one assumes that at least one further mutation is involved in PRA genesis.
The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. (Buccal swab order-form). If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.
Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer. Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
