Progressive Retinal Atrophy (prcd-PRA)

pra

PRA is a disease that causes the retina of the eye to degenerate slowly over time, the result is declining vision and eventual blindness. Progressive rod-cone degeneration (prcd) is just one type of PRA that has been found in the Giant Schnauzer. A DNA test for this type of PRA only is available via:

Optigen

Laboklin

This DNA test can be completed either by simple cheek swabs posted back to the appropriate lab or a blood sample taken by your vet, see the test providers websites for more information.

 


Additional DNA Tests Relevant to the Giant Schnauzer

Dilated Cardiomyopathy (DCM)

Dilated Cardiomyopathy (DCM)

Testing of a UK Giant diagnosed with DCM, found the same mutation as presented in Standard Schnauzers. The affected dog’s litter (9 pups) and parents were tested; both parents carried one copy of the mutation; 3 puppies were ‘Normal’; 3 puppies were ‘Carriers’; 3 puppies ‘Affected’. In 2014 when the mutation was discovered in the Giant Schnauzer, the University of Misourri (UoM) stressed that they had not tested enough Giant Schnauzers to give any estimate of frequency of the mutation in the breed or a predisposition of coat colour.

Concerned Giant Schnauzer breeders may order the DCM test through UoM’s partnership with the OFA (Orthopedic Foundation for Animals) by visiting www.offa.org
