What It Is
IFT122-PRA is a genetic form of progressive retinal atrophy associated with the IFT122 gene, which is involved in ciliary transport and normal photoreceptor maintenance.
Also Called: IFT122-PRA; IFT122-associated PRA
Abbreviation: IFT122-PRA
The Idiot-Proof Explanation
This is another specific genetic route to inherited retinal degeneration. The owner sees the same kind of problem eventually: worse vision, less confidence, possible blindness. The breeding side is where the subtype name really matters, because the wrong test gives the wrong comfort.
What Causes It
This subtype is associated with IFT122, a gene involved in cellular transport functions important to photoreceptors. When that system is genetically disrupted, the retina can degenerate over time.
The disease belongs under the PRA umbrella, but the test target is specific. That is why this page exists instead of cramming everything into one genetic alphabet soup paragraph.
- This is an inherited retinal disease variant.
- Testing should match the specific breed and suspected PRA form.
- Carrier and affected status matter for breeding decisions.
Bottom line: IFT122-PRA should be treated as its own testing lane under the bigger PRA umbrella.
What This Means for Life With This Dog
For pet owners, the main reality is progressive vision loss management and safety planning.
For breeders, the main reality is preventing affected puppies with accurate variant testing and honest pairing decisions.
Can It Be Fixed?
IFT122-PRA cannot be cured. Care focuses on diagnosis, monitoring, safe home setup, and responsible breeding prevention.
Symptoms Owners May Notice
Reduced night vision: The dog may hesitate in low light or become less confident after dark.
Progressive blindness: Vision can continue declining as retinal degeneration progresses.
Navigation mistakes: Bumping, misjudging steps, or acting uncertain in new places may show up as compensation starts failing.
Retinal changes on exam: A veterinary ophthalmology exam may detect changes an owner cannot see from the couch.
Treatment Options
DNA testing: Use the variant-specific test when appropriate for the breed. Do not treat one PRA test as a universal hall pass.
Ophthalmology monitoring: Eye exams help document progression and watch for secondary problems.
Home safety management: Predictable furniture, blocked hazards, and clear routines help a visually impaired dog function with less chaos.
Recovery and Aftercare
There is no cure or recovery. Long-term care is about safety, monitoring, and breeding decisions that do not manufacture preventable blindness.
What Happens If You Wait
Delay does not buy vision back.
Waiting mainly delays preparation and responsible breeding action. Genetic retinal disease does not care that everyone was hoping the test was unnecessary.
Cost Reality Check
Costs usually center on DNA testing, eye exams, monitoring, and home safety rather than curative treatment.
| Care Level | What It May Include | Estimated Cost |
|---|---|---|
| Initial workup | Variant DNA test and baseline eye screening. | $100-$500 |
| Ongoing management | Follow-up eye exams, additional PRA testing if needed, and home safety changes. | $300-$1,500+ |
| Severe case | Specialist diagnostics or secondary eye complications. | $1,000-$4,000+ |
Budget Reality Check
| Budget Item | Estimated Cost |
|---|---|
| Variant-specific DNA test | $60-$250+ |
| Eye screening | $50-$250+ |
| Ophthalmology consult | $250-$700+ |
Lifetime Cost Reality
| Case Pattern | Possible Lifetime Cost |
|---|---|
| Breeding test only | $60-$500+ |
| Affected dog monitoring | $500-$3,000+ |
| Complicated eye care | $2,000-$6,000+ |
Tell Me What I Should Really Expect
IFT122-PRA is a specific PRA lane, not a decorative acronym.
The dog still needs vision-loss support, but breeders need to understand the variant. Correct testing is the difference between responsible screening and checking a random box because it made the spreadsheet look calmer.
