Congenital stationary night blindness (CSNB)
The Briard suffers from a retinal disorder characterized by congenital night blindness with various degrees of visual impairment under photo topic illumination. The vision of affected dogs can range from normal day vision to profound day blindness. The disease generally appears first in early whelpage, at about six month and results from a mutation in the RPE65 gene. Along with the visual impairment, affected dogs have abnormal electroretinograms (ERG).
Trait of inheritance
1-2 weeks after arrival of the sample in the lab
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.
