Abstract excerpt
Mendelian susceptibility to mycobacterial disease (MSMD) is a rare inborn error of immunity characterized by heightened susceptibility to low-virulence non-tuberculous mycobacteria. Despite the widespread application of next-generation sequencing, the molecular etiology of approximately 50% of patients remains elusive. To date, 22 genes have been implicated, all converging on the IL-12/23-IFN-γ circuit,...
