A 31-year-old man had disseminatedMycobacterium avium complex (MAC) infection. The production of IFN-γ by peripheral blood mononuclear cells stimulated with phytohemagglutinin (PHA-PBMCs) was found severely impaired (40.7 pg/mL compared with 833 ± 289 pg/mL for the patient's and healthy subjects' (n = 3) PHA- PBMCs, respectively), and the patient's PHA-PBMCs completely lacked surface IL-12 receptor β1 (IL-12Rβ1) chain. The IL-12Rβ1 gene transcript in his PHA-PBMCs had an R213W substitution in each allele. Family history showed that both parents were heterozygotes in the R213W substitution. Transfection of a human embryonal kidney cell line 293 (HEKC293) with wild-type IL-12Rβ1wt gene led to cell surface IL-12Rβ1 expression; however, no expression was seen in HEKC293 transfected with the mutated IL-12Rβ1R213W gene. TheIL-12Rβ1 gene transcript, but no IL-12Rβ1 protein, was detected in PHA-PBMCs and T cells, suggesting a post-translational event(s), most likely a shortened turnover of the protein.
