Abstract excerpt
PURPOSE: To report a patient with a novel MSN mutation causing X-linked moesin-associated immunodeficiency (X-MAID) and investigate its pathogenic mechanisms. METHODS: Clinical and immunological data of the patient were collected. Autoantibody levels were measured using antigen microarrays. Whole-exome sequencing was performed to identify gene mutations. The stability of the mutant MSN protein was analyzed via...
