Isolated Respiratory Failure as the Presenting Symptom of Muscle-Specific Kinase Myasthenia Gravis: A Case Report and Literature Review.

Introduction: Anti-MuSK antibodies obstruct MuSK binding sites, leading to acetylcholine receptor (AChR) displacement within the postsynaptic membrane. MuSK MG patients often exhibit bulbar involvement and respiratory crises, setting them apart from other MG subtypes.

Case Presentation: A case of a 51-year-old male with MuSK MG that presented as isolated respiratory failure was compared to similar cases in the literature.
