Spondylocostal dysostosis is an inherited condition that causes limb skeletal growth abnormalities. Miniature Schnauzers affected by this disease will exhibit shorter bodies, along with vertebral and rib abnormalities. These abnormalities can include misalignment, fusion, and reduction in the number of vertebrae.
HES7
Autosomal recessive
Dogs affected by this disease are often stillborn due to extreme skeletal abnormalities. They may present with a shorter body and shorter limbs. Other abnormalities may include cleft palate and umbilical hernia.
A veterinarian will conduct a thorough exam, including a review of health history and any clinical signs. 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.
