DNA test for Birman cat PKD and HCM screening

A vet flagging PKD and HCM risk in a Birman at three years old is exactly the kind of situation where a cat DNA health screen can genuinely add value — not to replace your vet's monitoring, but to give them clearer genetic data to work with. PKD1 (the mutation behind polycystic kidney disease) and the MYBPC3 mutation linked to HCM in cats are both testable markers, and knowing your cat's status can help shape how often your vet wants to run ultrasounds and how urgently. Before I point you toward a specific test, can I ask: is your Birman pedigree-registered, or is the breed background partly assumed? And are you mainly after the health screening, or do you also want the breed composition report?

That's a really common situation, and honestly it doesn't change the health screening value at all — the genetic markers for PKD1 and HCM-linked MYBPC3 are tested regardless of whether she's registered. The breed composition report will still be useful and might actually confirm or add nuance to the Birman identification. Given that your vet has specifically flagged both conditions, I'd point you toward the Basepaws Breed + Health Cat DNA Test. It's the most established cat DNA test available in the UK, covers both the PKD1 mutation and the cardiac MYBPC3 marker, and gives a full breed report alongside a wildcats index. The health report is presented in a format that's easy to share directly with your vet, which matters here.

Fair question to push on. The mixed reviews you'll see are mostly about the breed percentage estimates, which are genuinely less precise for cats than dog breed tests are — cat genomics is a less mature field. But the health mutation testing is a different thing entirely: screening for specific known mutations like PKD1 and MYBPC3 is straightforward molecular testing, and Basepaws is reliable for those. It's not the same as estimating breed admixture from thousands of markers. Where I'd set expectations honestly: a negative result on MYBPC3 doesn't fully rule out HCM, because there are other genetic variants and non-genetic causes — so your vet's echocardiogram monitoring should continue regardless. The DNA result is one piece of information, not a verdict.

Absolutely — and I'd be direct with your vet about that too. The MYBPC3 mutation accounts for a significant proportion of HCM cases in certain breeds, but HCM in cats can arise from other causes the DNA test won't catch. A clear genetic result lowers the risk profile somewhat and might reduce scan frequency, but your vet should make that call with the full picture. Think of the Basepaws result as useful context that goes into her file alongside the cardiology monitoring, not something that replaces it. For PKD1 specifically, a clear result is more definitive — that particular mutation is the primary known genetic driver of PKD in cats, so a negative there is genuinely reassuring.

It's a cheek swab — takes about thirty seconds if your cat cooperates, maybe a couple of minutes if she doesn't. You register the kit online, swab the inside of her cheek, let it dry, and post it back in the prepaid envelope. Results typically come back in four to six weeks, and you get them through the Basepaws online portal where you can also download a PDF to share with your vet. The Basepaws Breed + Health Cat DNA Test is available on Amazon UK — search that exact name and it should come up as a Prime-eligible listing. It's the one to go for given your vet's specific concerns.
