title: Mycobacterium fortuitum-chelonae complex infection in a child with complete interleukin-12 receptor beta 1 deficiency.
abstract: A 10-year-old boy had chronic diarrhea, abdominal pain, severe weight loss and hepatomegaly; multiple enlarged para-aortic and mesenteric lymph nodes. Mycobacterium fortuitum-chelonae complex was identified in the culture of the lymph nodes. Interleukin-12 receptor beta 1 expression could not be observed in phytohemagglutinin-driven T cell blasts. A homozygous missense interleukin-12 receptor beta 1 mutation was found (R173P).
