Disease overview

Muscular dystrophy is a group of degenerative muscle disorders that are characterized by progressive muscle dysfunction. Ullrich congenital muscular dystrophy (UCMD) is caused by a mutation in a gene that produces collagen VI, a protein that is crucial for the muscle.

Gene name

COL6A1

Inheritance

Autosomal recessive

Signs and symptoms

Affected dogs will show general signs of muscle degeneration at a young age. This is a severe form of muscular dystrophy, and typically leads to euthanasia between 5-15 months of age.

How is it diagnosed

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.
