Retinitis pigmentosa is an inherited retinal degenerative disease that causes slow but progressive vision loss due to a gradual loss of the light - sensitive retinal cells called rods and cones.

Breeders have a number DNA tests at their disposal to check for the Multi Drug Resistance Gene, hereditary cataracts, Pelger Huet Anomaly, Collie Eye Anomaly and Progressive Rod Cone Degeneration (another eye disease), so check which testing your breeder uses.

Tested to determine the progressive rod - cone (prcd) / PRA and CEA (collie eye anomaly) DNA status «Clear, Carrier or Affected» if unknown by parentage.

Progressive Retinal Atrophy (PRA) is an inherited disease of the retina (tissue layer at the back of the eye containing the rods and cones) where the retina slowly degenerates with time.

This is different from typical progressive retinal degeneration (PRA), which involves both the rod and cone cells of the retina causing night blindness and worsening day vision.

The most common type of PRA is progressive rod - cone dysplasia (prcd) which is known to affect Labrador retrievers and poodles and possibly as many as sixty other breeds.

Less frequently seen are progressive rod cone degeneration (a form of progressive retinal atrophy), collie eye anomaly, iris coloboma, and persistent pupilary membrane.

In Australian Shepherds, we commonly do DNA tests for MDR1, a drug reaction mutation; HSF4, a gene with mutations that cause cataracts, one of which causes most of the cataracts I Aussies; as well as Collie Eye Anomaly and the progressive rod - cone degeneration form of Progressive Retinprogressive rod - cone degeneration form of Progressive RetinProgressive Retinal Atrophy.

Other eye diseases include, roughly in order of frequency, cataract, distichiasis, progressive rod - cone degeneration (a form of PRA), CEA, iris coloboma, persistent pupilary membrane, cone degeneration, and canine multifocal retinopathy.

Mutation frequency for Collie Eye Anomaly (CEA) and Progressive Rod Cone Degeneration (PRCD, a form of PRA) in the breed is much lower.

The most common eye diseases in the breed are cataracts, distichiaisis, persistent pupilary membrane, and iris coloboma, with Progressive Rod Cone Degeneration (PRCD), a form of progressive retinal atrophy (PRA), Collie Eye Anomaly (CEA), Canine Multifocal Retinopathy (CMR), and glaucoma have been seen buProgressive Rod Cone Degeneration (PRCD), a form of progressive retinal atrophy (PRA), Collie Eye Anomaly (CEA), Canine Multifocal Retinopathy (CMR), and glaucoma have been seen buprogressive retinal atrophy (PRA), Collie Eye Anomaly (CEA), Canine Multifocal Retinopathy (CMR), and glaucoma have been seen but are rare.

If the disease is uncommon, as with the progressive rod - cone degeneration (PRCD) form of Progressive Retinal Atrophy in Australian Shepherds, or if use of a test and careful breeding decisions have markedly reduced the frequency of a formerly common mutation (think what could be done with CEA in Collies,) testing could then be confined to only those dogs with known family history of the disease or with relatives that have been DNA tested aprogressive rod - cone degeneration (PRCD) form of Progressive Retinal Atrophy in Australian Shepherds, or if use of a test and careful breeding decisions have markedly reduced the frequency of a formerly common mutation (think what could be done with CEA in Collies,) testing could then be confined to only those dogs with known family history of the disease or with relatives that have been DNA tested aProgressive Retinal Atrophy in Australian Shepherds, or if use of a test and careful breeding decisions have markedly reduced the frequency of a formerly common mutation (think what could be done with CEA in Collies,) testing could then be confined to only those dogs with known family history of the disease or with relatives that have been DNA tested as carriers.

The most widespread form of PRA is progressive rod - cone degeneration (prcd) and affects many breeds including Poodles, American and English Cockers, Labrador Retrievers, Chesapeake Bay Retrievers, Golden Retrievers, and Portuguese Water Dogs.

Miniature and Toy Poodles, American and English Cocker Spaniels, Portuguese Water Dogs, and Labrador Retrievers have a form of PRA called progressive rod - cone degeneration (prcd).

Genes associated with the following forms of inherited canine retinal diseases were tested for association using fragment analysis in 11 PRA - affected and 11 unaffected Swedish vallhund dogs: canine multifocal retinopathy (cmr; gene: BEST1)[8], [9], rod - cone dysplasia type 1 (rcd1; PDE6B) and type 3 (rcd3; PDE6A)[23]--[26], progressive rod - cone degeneration (prcd; PRCD)[27], canine Leber congenital amaurosis (LCA; RPE65)[6], [7], cone - rod dystrophy (crdSWHD, NPHP4)[28], and achromatopsia / cone degeneration (ACHM / cd; CNGB3)[29], [30].
