Congenital Myasthenic Syndrome (CMS)

Congenital Myasthenic Syndrome (CMS)is a hereditary disease that can be tested with a DNA test. Congenital myasthenic syndrome (CMS) is a neuromuscular disorder characterized by severe generalized skeletal muscle weakness caused by disruption of signal transmission across the neuromuscular junction. The hereditary disease usually occurs in animals between 6 to 12 weeks of age. In Old Danish Pointing Dog affected dogs are able to run normally for 5-30 minutes after which they take shorter and shorter strides and eventually fall down with flexed fore- and hind legs. After some minutes rest, they are able to walk and run again.
