autosomal recessive Mendelian susceptibility to mycobacterial diseases due to partial IFNgammaR1 deficiency
A genetic variant of Mendelian susceptibility to mycobacterial diseases characterized by a partial deficiency in IFN-gammaR1, leading to a residual response to IFN-gamma and, consequently, to recurrent, moderately severe infections with bacillus Calmette-Guerin (BCG) and other environmental mycobacteria (EM).
