Congenital myasthenic syndromes (CMSs) are a group of rare genetic disorders of the neuromuscular junction resulting in structural or functional causes of fatigable weakness that usually begins early in life... CMS was first recognized in dogs in 1974 as an autosomal recessive trait in Jack Russell Terriers (JRTs). (Rinz et al 2015)

Application in the Breed
Carriers may be bred to normal animals (N/cms x N/N) . Offspring should be tested before breeding . No breeding of two carriers (N/cms x N/cms) nor of affected animals. Exercise intolerance (temporarily paralyzed) (4 months of age) - No increase in severity with age.
