?:definition
  • A genetic variant of mendelian susceptibility to mycobacterial disease with characteristics of a partial deficiency leading to impaired IFN-gamma immunity and consequently recurrent moderately severe infections with bacillus Calmette-GuĂ©rin (BCG) and other environmental mycobacteria. Caused by heterozygous mutations in the IFNGR1 gene on chromosome 6q23-q24 that encodes the IFN-gamma receptor ligand binding chain. Microdeletion 818del4 is by far the most common mutation and it corresponds to the first documented hotspot for a microdeletion in the human genome. It leads to the expression of IFN-gamma receptor on the cell surface with no signal transduction and therefore patients only show a partial response to IFN-gamma. Transmission is autosomal dominant.
