University of Helsinki researchers have uncovered a novel gene associated with acute respiratory distress syndrome (ARDS) in dogs. Pictures of blood plasma The new research on this fatal disease may also help us understand the mechanisms of respiratory diseases in humans.


A new genetic study has uncovered the cause of acute respiratory distress in Dalmatian dogs. Chemical composition of blood plasma ADRS has an early onset, with puppies or young dogs experiencing difficulty in breathing, which rapidly leads to death. Difference between blood serum and blood plasma The gene study used material which was previously collected at the University of Helsinki Veterinary Teaching Hospital as well as canine biobank samples.

“There are many causes for lethal acute respiratory distress. What is the composition of blood plasma In humans, the underlying cause is often pneumonia, inflammation or pulmonary fibrosis. Structure of blood plasma In Dalmatians, the cause is a genetic lung tissue disorder. Parts of blood plasma Our study indicates that the disorder results from a defect in an anillin protein which binds to actin, the supporting microfilaments in the cell,” explains Professor Hannes Lohi.

“Anillin has an important role in cell division and growth. How to extract plasma from blood The lung injury in the affected dogs seems to be related to an abnormal regeneration capacity of the bronchiolar epithelium. Does plasma contain white blood cells The ANLN gene discovery is in line with this manifestation of the disease. Describe the composition of blood plasma In addition, some of the affected dogs only had one kidney, while some had hydrocephalus. Blood plasma is This suggests that ANLN has broader significance for the development of the epithelium in different organs,” states Dr Marjo Hytonen.

“This gene discovery provides new insights into the mechanisms of lung injuries. What is a blood plasma Typically, lung injuries in the affected Dalmatians are associated with disorders in the cellular regeneration and intercellular junctions. Color of blood plasma The lack of anillin, the actin-binding protein, can perfectly explain the changes which we see on the cellular level. What does plasma in the blood do Due to the malformed epithelial structure, inhaled air is trapped in the alveolar level, over-extending the alveolar walls,” explains veterinary pathologist, LicVetMed Pernilla Syrja.

Gene test to provide exact information for diagnostics and breeding

In the future, the research results can help diagnose the illness and eradicate it from the breed.

“We tested more than 180 Dalmatians and 30 Pointers to find the mutation associated with the disease. What is the blood plasma Less than 2% of the Dalmatians carried the mutation, while none of the Pointers did. What is the percentage of plasma in blood ARDS has been known for a long time in the breed, and breeders have learnt to avoid risk lines, which is likely the cause of the low carrier frequency. Major components of blood plasma However, it is challenging to eradicate a condition from the breed in recessive disorders such as ARDS without genetic testing, as the carrier dogs do not have the disease. Components of plasma in blood Both parents must be carriers for the disease to manifest, so affected puppies will have inherited the mutation from each parent,” states LicVetMed Saila Holopainen.

The gene test will be made available as part of the MyDogDNA test ( www.mydogdna.com).
