Progressive Retinal Atrophy

Our DNA test for Progressive Retinal Atrophy is ideal for breeders and owners who want the reassurance of genetic health testing.

The guideline turnaround time for single tests is approximately 10-12 working days after the swab arrives at the lab. 

If you need more than two tests it is often more cost-effective to order the relevant breed package.

Description

Progressive Retinal Atrophy (PRA) is a group of eye disorders which cause progressive degeneration of the retina through thinning and decreased blood flow. Depending on the variant the rod (dim light) or cone (bright light) photoreceptor cells of the eye may also be affected and age of onset and speed of progression can vary. Affected dogs typically have initial vision loss in low light, then peripheral vision loss, and eventually total blindness.

An autosomal recessive condition caused by a mutation in the CNGA1, RPGRIP1, NPHP4, ADAM9, CNGB1, PRCD, PDE6B, RD3, PDE6A, C2orf71, FAM161A, SLC4A3, or TTC8 gene.
