CONTEXT Signal transducer and activator of transcription 5b (STAT5b) deficiency, first reported in a patient who carried a p.Ala630Pro missense mutation in the Src homology 2 (SH2) domain, results in a rare clinical condition of GH insensitivity (GHI), IGF-I deficiency (IGFD), and severe immune dysregulation manifesting as progressive worsening of pulmonary(More)
BACKGROUND Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by inborn errors of the phagocyte nicotinamide adenine dinucleotide phosphate oxidase complex. From the first year of life onward, most affected patients display multiple, severe, and recurrent infections caused by bacteria and fungi. Mycobacterial infections have also(More)
Two populations of human natural killer (NK) cells can be identified in peripheral blood. The majority are CD3(-)CD56(dim) cells while the minority exhibits a CD3(-)CD56(bright) phenotype. In vitro evidence indicates that CD56(bright) cells are precursors of CD56(dim) cells, but in vivo evidence is lacking. Here, we studied NK cells from a patient that(More)
Chronic granulomatous disease (CGD) is a primary immunodeficiency that affects the oxidative mechanism of microbial killing of phagocytic cells. The defect is characterized by a lack or severely reduced superoxide anion (O2-) production by phagocytes. Seventy percent of CGD cases are X-linked (X-CGD) and they are caused by mutations in the gene encoding for(More)
BACKGROUND Autosomal dominant anhidrotic ectodermal dysplasia with immune deficiency (AD EDA-ID) is caused by heterozygous point mutations at or close to serine 32 and serine 36 or N-terminal truncations in IκBα that impair its phosphorylation and degradation and thus activation of the canonical nuclear factor κ light chain enhancer of activated B cells(More)
