Plain-English summary
Recent advances in genetics have improved how we understand and diagnose skin diseases in pets like dogs, cats, and horses. There are now various genetic tests available that can help veterinarians identify skin conditions that might not show clear symptoms. These tests are also valuable for responsible breeding, as they can help reduce the chances of passing on hereditary skin issues. As these genetic testing methods become more common in veterinary practice, it's important for veterinarians to know how to use and interpret the results correctly. Overall, the use of genetic testing is becoming a key part of diagnosing and managing skin diseases in pets.
Abstract
BACKGROUND: Molecular genetics has made significant advances in the analysis of hereditary dermatoses during the last several years. OBJECTIVES: To provide an update on currently available genetic tests for skin diseases of dogs, cats and horses, and to aid the veterinary clinician in the appropriate selection and applications of genetic tests. METHODS: The scientific literature on the topic was critically reviewed. The list of known causative variants for genodermatoses and hair morphology traits was compiled by searching the Online Mendelian Inheritance in Animals (OMIA) database. RESULTS: Genetic testing has become an important diagnostic method in veterinary medicine. Genetic tests can help to establish the correct diagnosis in some diseases with relatively nonspecific signs. Genetic tests are also essential for sustainable breeding programmes and to help minimize the frequency of animals with hereditary diseases. Advances in genetic methodology and bioinformatics already allow genome-wide screening for potential disease causing mutations for research purposes. It is anticipated that this will become a routine process in clinical practice in the future. CONCLUSION AND CLINICAL IMPORTANCE: As specific DNA tests and broad genome-wide analyses come into more common use, it is critical that clinicians understand the proper application and interpretation of these test results.
