IRAK-4 deficiency is a rare inherited primary immunodeficiency that is characterized by severe recurrent pyogenic bacterial infections. Individuals with IRAK-4 deficiency seem to be particularly susceptible to infections caused by bacteria called Streptococcus pneumoniae. The deficiency is caused by mutations in a gene called IRAK4 (interleukin 1 receptor-associated kinase 4).  The IRAK4 gene provides instructions for making an enzyme that is crucial for protective immunity against specific bacterial infections.
