Genetic testing in veterinary dermatology.
Abstract: Molecular genetics has made significant advances in the analysis of hereditary dermatoses during the last several years. Objective: 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. Conclusions: 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.

Summary
This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.
The research article primarily investigates the progress and efficacy of genetic testing in diagnosing hereditary skin diseases in dogs, cats, and horses, as well as its implications for breeding programs.
Objective and Methods
The researchers embarked on this study to update readers on the genetic tests available for diagnosing skin diseases in dogs, cats, and horses. They also looked at guiding veterinary clinicians on how to appropriately select and apply these tests. The approach used to achieve these objectives involved a critical review of relevant scientific literature.
Additionally, the research team compiled a list of known causative variants for genodermatoses (genetically inherited skin diseases) and hair morphology traits by exploring the Online Mendelian Inheritance in Animals (OMIA) database.
Results
The results of the research revealed that:
- Genetic testing is crucial for diagnosing certain diseases that have relatively non-specific symptoms, establishing its importance in veterinary medicine.
- For breeding programs to be sustainable and to minimize the number and spread of animals with hereditary diseases, genetic testing is essential.
- Due to advancements in bioinformatics and genetic methodology, genome-wide screening for potential disease-causing mutations is now possible for research purposes. This process is expected to become commonplace in clinical practice over time.
Conclusions
The study concludes that as DNA tests and broad genome-wide analyses become increasingly prevalent, it is crucial for clinicians to grasp how to correctly apply and interpret these test results. This understanding is fundamental to ensure the effective use of genetic testing in both diagnostic applications and decision-making processes for breeding programs.
