Beth,

According to the MG Manual:

Autoimmune MG is not transmitted by mendelian inheritance, but family members of patients are approximately 1,000 times more likely to develop the disease than is the general population.

Myasthenia Gravis: A Manual for the Health Care Provider (PDF) - page 13

When I looked into the mirror, as my symptoms become more severe during my recent MC crisis, I saw my dad's face. He often had a droopy eye. He also had a lack of effect in his expression, like his face muscles were inhibited.

During WWII my dad was an infantry Sargent in the Philippines. He contracted malaria while serving. During his later adult live he would have periods of disability, what was described as a flare up of malaria.

Looking back at these these bouts of disability (usually lasting 3 to 6 days), they may very well have been MG crises events. If so, these events were mild in comparison to my two events.

P.S.: Mike introduced me to the MG manual in January when I first joined the forum.
