Severe combined immunodeficiency disease is an immune disorder characterized by an absence of white blood cell production, which is crucial for immune response. This disease affects both B-lymphocytes, which are responsible for the production of antibodies, as well as T-lymphocytes, which are used in immune response and signaling.

Autosomal recessive
Clinical signs may include lethargy, vomiting, diarrhea, and failure to thrive. Affected dogs typically have shorter lifespans, as they are highly susceptible to bacterial, viral, and parasitic infections.
A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. Laboratory tests are needed to determine causes of infection. Genetic testing is necessary to determine if there is an underlying genetic cause, which can assist veterinarians with diagnosis and help breeders identify affected and carrier dogs.
