The patient will then develop MG-like symptoms such as ptosis, diplopia, proximal muscle weakness, respiratory weakness, etc. Diagnosis of this adverse event remains difficult as cases present rapidly and typical testing for MG would include nerve conduction studies as well as autoantibody (anti-acetylcholine receptor (AChR) and anti-muscle-specific kinase (MuSK)) titers [6]. This evidence concerns the gene MUSK and ptosis.
