title: Bacille Calmette-Guérin lymphadenitis and recurrent oral candidiasis in an infant with a new mutation leading to interleukin-12 receptor beta-1 deficiency.
abstract: Mendelian susceptibility to mycobacterial diseases (MSMD) is a rare syndrome characterized by predisposition to infections caused by weakly virulent mycobacteria, such as those in bacille Calmette-Guérin (BCG) vaccine and environmental mycobacteria. Salmonellosis has been reported in almost half of affected patients. Patients are also vulnerable to Mycobacterium tuberculosis infection. Several other infectious diseases may occur, albeit rarely. Mucocutaneous candidiasis is more common. Interleukin-12 receptor beta1 (IL-12Rbeta1) deficiency is the most frequent genetic cause of MSMD. Here, we describe an infant with a single episode of BCG lymphadenitis who also suffered from recurrent oral candidiasis. Genetic analysis revealed a new homozygous mutation (64+1G>T) in the IL12RB1 gene that caused complete IL-12R1beta1 deficiency. IL-12Rbeta1 deficiency should be considered in patients with BCG infection, even in those who experience a single episode of BCG lymphadenitis or recurrent mucocutaneous candidiasis. Every attempt should be made to heighten awareness in countries where BCG vaccination is performed.
