Health pillar / DNA
Genetic screening: HUU, CMR1 & DM
A DNA result identifies a tested variant; it is not a complete health certificate. Results are most useful when the dog’s identity, laboratory, genotype and mating context are documented.
Three commonly discussed tests
HUU relates to urate handling and urinary stone risk; CMR1 is associated with a retinal disorder; DM is associated with risk for a late-onset neurological disease. Laboratory terminology and breed relevance must be interpreted carefully.
- Clear, carrier and at-risk/affected terminology describes genotype, not the whole dog.
- A carrier can be used responsibly with an appropriately tested mate while preserving genetic diversity.
How to read a certificate
Match registered name or microchip, sample method, laboratory, test name, result and report date. Ask how the result influenced the pairing rather than treating one badge as proof of complete health.
- DNA screening does not replace respiratory, cardiac, orthopaedic, eye or clinical assessment.
