Other Genetic Conditions
Advances in canine genetic testing have greatly improved our understanding of inherited disease within the Cane Corso. In addition to conditions such as DSRA, genetic screening panels may identify variants associated with a range of other hereditary disorders.
The presence of a genetic variant does not necessarily mean a dog will develop clinical disease. Some conditions demonstrate incomplete penetrance, variable expression or require additional genetic and environmental factors before symptoms occur. Genetic test results should therefore be interpreted alongside veterinary advice, clinical findings and responsible breeding practices.
As testing becomes more widespread, continued monitoring and health reporting will help improve our understanding of the significance of these conditions within the breed.
Copper Toxicosis
Copper Toxicosis is an inherited disorder affecting copper metabolism within the liver. Affected dogs accumulate excessive amounts of copper within liver tissue, which may eventually lead to chronic inflammation, liver damage and liver failure.
Clinical signs can include lethargy, reduced appetite, weight loss, vomiting, increased thirst, jaundice and abdominal discomfort. However, many affected dogs show no obvious symptoms during the early stages of disease.
Genetic variants associated with Copper Toxicosis have been identified in some Cane Corso populations through commercial DNA testing. Further research is required to better understand the prevalence and clinical significance of these findings within the breed.
DVL2 Variant
The DVL2 (Dishevelled Segment Polarity Protein 2) gene variant has been associated with a range of structural characteristics in several dog breeds, including shortened or screw-shaped tails, vertebral abnormalities and alterations in skeletal development.
Within the Cane Corso, the DVL2 variant has been identified through genetic testing and may contribute to congenital tail deformities commonly referred to as "Corkscrew Tail" or "Screw Tail". Affected dogs may display kinks, twists or abnormal curvature of the tail, ranging from minor cosmetic changes to more significant structural abnormalities.
Current research suggests that the DVL2 variant may influence multiple aspects of skeletal development, although the extent of its impact can vary considerably between individuals. Not all dogs carrying the variant will display obvious clinical signs, and further research is ongoing to better understand its significance within the breed.
As genetic testing becomes more widely utilised, breeders can use available information alongside health screening, conformation assessment and pedigree analysis to make informed breeding decisions that support the long-term health and welfare of the Cane Corso.
Canine Multifocal Retinopathy 1 (CMR1)
Canine Multifocal Retinopathy 1 (CMR1) is an inherited eye condition that affects the retina, the light-sensitive tissue located at the back of the eye. The condition causes characteristic retinal lesions which may vary in severity between affected dogs.
Many dogs with CMR1 retain functional vision and may show few or no obvious clinical signs, while others may experience varying degrees of visual impairment.
Genetic testing has identified the CMR1 mutation within the Cane Corso population. Responsible use of DNA testing can help breeders make informed breeding decisions and reduce the risk of producing affected offspring.
Laryngeal Paralysis & Polyneuropathy (LPPN)
Laryngeal Paralysis & Polyneuropathy (LPPN) is a hereditary neurological disorder affecting both the nerves controlling the larynx (voice box) and the peripheral nervous system.
Affected dogs may develop noisy breathing, exercise intolerance, changes in bark, weakness, altered gait, reduced coordination and progressive neurological dysfunction. Severity can vary considerably between individuals.
Genetic variants associated with LPPN have been identified through DNA screening programmes, including within some Cane Corso populations. As awareness and testing increase, further information will become available regarding the significance and prevalence of this condition within the breed.
As advances in veterinary genetics and DNA technology continue to evolve, our understanding of inherited disease within the Cane Corso is constantly expanding. Modern genetic screening panels are capable of identifying an increasing number of hereditary conditions, genetic risk factors and previously unrecognised variants, providing breeders and owners with valuable tools to support informed decision-making.
Not every genetic variant will result in disease, and ongoing research continues to improve our understanding of how genetics, environment and overall health interact. As new discoveries emerge, recommendations and testing options may change to reflect the latest scientific knowledge.
The ICCGB supports evidence-based health initiatives, responsible use of genetic testing and continued participation in health research. By embracing new technologies and sharing health information responsibly, we can work together to improve our understanding of breed health and safeguard the future of the Cane Corso for generations to come.
