DNA test for Ragdoll cat HCM risk

Your vet flagging HCM risk in a Ragdoll is genuinely important — it's the most common inherited heart disease in cats, and Ragdolls carry a higher-than-average genetic susceptibility. Consumer DNA tests for cats have improved a lot recently, and some do screen for the MYBPC3 mutation linked to feline HCM, but I want to be upfront: a positive genetic result doesn't mean your cat has HCM, and a negative doesn't rule it out — the mutation only explains part of the picture. That said, it can add a useful data point alongside your vet's echocardiogram. Is your cat a purebred Ragdoll with known breeding, or is there some uncertainty about the background? And is your main goal the HCM-specific mutation screening, or do you also want a broader health and trait report?

That context is really helpful — and honestly, it's a sensible approach from your vet. If she tests negative for the MYBPC3 variant, that doesn't eliminate HCM risk entirely, but it does shift the probability picture and could reasonably influence how often echocardiograms are scheduled. For a purebred Ragdoll where health screening is the priority, I'd point you toward the Basepaws Breed + Health Cat DNA Test. It's the most clinically credible consumer cat DNA test available in the UK right now, and it specifically includes the feline HCM genetic markers including MYBPC3. You get a written report you can actually share with your vet. The breed breakdown will largely confirm what you already know given her papers, but the health screening is the substantive part here.

It's a fair question to ask before spending the money. The health screening covers over 40 genetic markers — HCM is the headline one for Ragdolls, but it also includes PKD (polycystic kidney disease), blood type, and various other inherited disease markers that are relevant across cat breeds. For a Ragdoll specifically, the HCM and blood type results are probably the most actionable. The breed analysis is thorough but, as you said, less relevant when you have papers. It's not a substitute for the echo your vet may still recommend — think of it as information that goes into the same conversation, not a replacement for clinical cardiology screening.

Yes, it's a simple cheek swab you do at home — takes about thirty seconds if your cat is reasonably cooperative, and most are fine with it. You register the kit online, swab the inside of her cheek, seal it in the prepaid envelope, and post it back. Results typically come through in three to six weeks via an online portal, and the report is formatted clearly enough that it's worth printing and bringing to your next vet appointment. Given your vet has already mentioned the MYBPC3 mutation by name, they'll know exactly what to do with the result.

Good call — and it sounds like you're approaching this exactly the right way, using it as one piece of information alongside proper veterinary cardiology follow-up rather than instead of it. Hope the result gives you and your vet something useful to work with. If she does go on to have echos, keeping a record of both the genetic result and the scan findings over time is genuinely valuable for Ragdolls.
