Retrospective Study :Describe the Changes of the Disease in Many Cases Likely to Aggravate.
The aim of this study is to better understand the action of hormonal factors that are
presumably incriminated for the fluctuation of the disease. The investigators would also
like to better adress the issues of women with Congenital Myasthenic Syndrome, who desire a
pregnancy : the possibility of decompensation, the problems that can arise during the course
of the childbearing, the risk of foetal malformations.
Observational Model: Cohort, Time Perspective: Retrospective
