Hypertrophic Cardiomyopathy (HCM)

Hypertrophic Cardiomyopathy (HCM) is found in all breeds, not just Sphynx. HCM is the most common heart disease found in all domestic cats. This is a genetic disease that can happen at any time to any breeder regardless of scanning and precautions. HCM is a thickening of the left ventricle wall of the heart. Many cats that have heart conditions show no symptoms (ie heart murmur) when checked by a non-specialist vet.
Some breeders are proactive and scan their breeders annually at board certified cardiologists to ensure they are breeding healthy cats. This is the best tool we have right now, however it is not a guarantee because the gene has variable expression and can express itself at any time. Make sure the breeder you are working with scans yearly!
Now, here is the information if you wish to help the breed find HCM. This is a study done by Dr. Meurs.
Sphynx Cat Hypertrophic Cardiomyopathy Study
We are still very interested in studying Sphynx hypertrophic cardiomyopathy to try to identify a genetic mutation for this disease. We are currently looking for more DNA samples from Sphynx cats. At this time we need more samples from the following:
1. Sphynx cats who DO NOT have hypertrophic cardiomyopathy who are at least 8 years of age
2. Sphynx cats who DO have hypertrophic cardiomyopathy
Please ask your veterinarian or a veterinary technician to pull a blood sample into an EDTA tube. Most veterinary hospitals have these readily available.
Blood drawn does not need to be mailed back with ice packs or be shipped overnight. However, if possible please try to send the sample within a few days by standard mail. Until the blood can be mailed, it is a good idea to refrigerate it (i.e., if the blood was drawn late Saturday and cannot be mailed until Monday, it’s a good idea to refrigerate it between Saturday and Monday).
