Novel nonsense IL-12Rβ1 mutation associated with recurrent tuberculosis.
Trial report in Immunologic research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The interleukin (IL)-12/interferon(IFN)γ axis plays an important role in the control of mycobacterial diseases as demonstrated by the increased susceptibility to mycobacterial species in patients with an inborn error of the IL-12-dependent IFNγ immunity. Here, we report a novel mutation in the IL-12Rβ1 gene in a female Pakistani patient who was born in a consanguineous marriage and developed severe bacille Calmette-Guérin (BCG) infection and recurrent tuberculosis. After reviewing the patient's clinical records, she was investigated for IL-12/IFNγ defects using enzyme-linked immunosorbent assay (ELISA), flow cytometry, and DNA genetic Sanger sequencing. Quantification of secretory cytokines from the patient's peripheral blood mononuclear cells (PBMCs) revealed significantly reduced IFNγ production. Flow cytometric analysis revealed no surface expression of IL-12Rβ1 on PHA-activated T lymphocytes. In addition, IL-12-induced impaired STAT4 phosphorylation in the patient's lymphocytes when compared with those from five healthy controls. The genetic analysis of IL-12Rβ1 gene identified a novel nonsense mutation c.199G>T/p.E67* within exon 3, which encodes part of the cytokine-binding region (CBR). In silico analysis indicates that this novel nonsense mutation generates a truncated protein with an apparent inactivating effect. Our data expand the genetic spectrum of IL-12Rβ1 deficiency. Moreover, our findings highlight the need for developing newborn screening for patients with primary immunodeficiency associated with mycobacterial infections in areas where BCG vaccination is mandatory in order to improve the treatment of patients, and consequently their quality of life.
