Myasthenia Gravis and other Myasthenic syndromes

Inheritance patterns and prenatal diagnosis

Inheritance patterns
There is a very weak familial susceptibility to MG and to other autoimmune diseases in the families of patients with MG and LEMS. However all CMS are genetic disorders, most are autosomal recessive, apart from the slow channel syndromes, which are autosomal dominant. It is important to be referred to your regional genetics centre for further information if a CMS is diagnosed.

Prenatal diagnosis
This is not applicable to MG and LEMS. Prenatal diagnosis is now possible for CMS families, once the exact genetic fault is identified.
