HGTD This week: Vets - what can HGTD do for you?
Aimee Llewellyn-Zaidi posted a blog entry in HGTD & Genetic Testing
Vets – what can HGTD do for you? Genetic testing is part of our dog's lives Just as genetic testing has become normalized in the human world, thanks to popular direct to consumer products like 23 and Me, or Ancestry.com, so it has in the veterinary world. While perhaps once the preserve of specialist dog breeders, it is increasingly common for vets in practice to have questions from clients about DNA testing. While covering the basics of testing and inheritance is part of many veterinary educations, it is unreasonable to expect anyone to have knowledge of the 300+ different genetic -
The continued review of breed-specific tests for assigning relevance ratings, and ongoing discussions with genetic experts has led to a refinement of the breed relevance ratings (please see: BRR) . To better accommodate the spectrum of genetic test validation, we’ve added a new orange BRR. The orange BRR indicates where all current available evidence has been reviewed, but the relevance is inconclusive. It could be that a mutation is detectable in a specific breed, but that there is no evidence that this correlates with clinical development of the disease/phene. It could also be that the

HGTD This Week, 7 Aug 2020: Canine Crime Scene Investigators When we think about genetic testing, we often focus on how it can be a tool to improve health and welfare - generally centered around breeding for health or finding more about the health or potential health risks for an individual dog. Knowing about health risks that are especially relevant to specific breeds or dog types makes testing even more powerful in helping reduce risks of disease or undesirable traits (see Breed Relevancy Ratings). Most commonly, genetic screening and diagnostic testing focuses on: disease tests, breed e

A recent article provided by the Golden Retriever Club of America, Golden Retriever Health and Genetics Highlight: Neuronal Ceroid Lipofuscinosis in Golden Retrievers, by Ann Hubbs and Ron Rubrecht,, discussed the challenges faced in Fall 2018, by a breeder who had unsuspectingly bred a litter of puppies from two carriers of neuronal ceroid lipofuscinosis (NCL 5) – a devastating neurological disease considered rare in the breed. While a DNA test existed, most Golden Retriever owners wouldn’t be aware of the condition, let alone testing options. The breeder did the absolute right thing when rea
