Abstract Futuristic Background

Myasthenia Gravis

Immune-mediated myasthenia gravis (MG) is a relatively common neuromuscular disease affecting dogs and, occasionally, cats. Acquired MG has been observed in dogs older than 3 months of all breeds, but particularly in German Shepherd Dogs, Golden Retrievers, and Labrador Retrievers. In one report, the relative risk of acquired MG in different breeds of dog was highest in Akitas. Newfoundlands and Great Danes may be predisposed to a familial form of acquired MG. A bimodal age of onset (<5 years and >7 years) has also been reported in affected dogs, and spayed females may have heightened risk. In cats, Abyssinians and the closely related Somalis seem to be overrepresented and gender is not a risk factor in cats.
