简要总结
This study is evaluating the safety and potential effects of AMP-101 in people with DOK7 Congenital Myasthenia Syndrome (CMS). Participants will receive a single dose of the study treatment and will be monitored to assess their health and response to treatment. Approximately 4 participants are expected to take part in the study.
