IRAK-4 haploinsufficiency can present with pneumococcal sepsis and poor pneumococcal vaccine response in adults. Further research can determine the significance of unrecognized pathogenic variants in in adults presenting with pneumococcal sepsis and the utility of immunoglobulin replacement in these patients.

IgG4-related disease is a chronic fibroinflammatory disorder that is becoming increasingly recognized in the pediatric population. The orbit is one of the most commonly affected sites. We present the youngest case of IgG4-related ophthalmic disease in the literature, with an immunodeficiency phenotype associated with a homozygous IRAK-4 variant gene.

Background: Human interleukin- (IL-) 1 receptor-associated kinase 4 (IRAK-4) deficiency is a recently described primary immunodeficiency. It is a rare, autosomal recessive immunodeficiency that impairs toll/IL-1R immunity, except for the toll-like receptor (TLR) 3- and TLR4-interferon alpha (IFNA)/beta (IFNB) pathways. .

Background/aim: Abnormal immune response occurs in individuals who have alleles associated with innate and adaptive immune mechanisms that predispose to inflammatory bowel disease (IBD). Interleukin-1 receptor-associated kinase 4 (IRAK-4) involved in the pathway produces cytokines that initiate and maintain inflammation through Toll-like receptors and interleukin-1 receptors on the membranes of innate immune cells are stimulated with antigens. It was aimed to investigate whether IRAK-4 rs3794262 and rs4251481 polymorphisms predispose to IBD and the possible effects of these polymorphisms by examining these gene polymorphisms with the clinic and prognostic parameters of IBD.
