IRAK4 deficiency

IRAK-4 deficiency

Overview

Type of disease: Rare conditions

IRAK-4 deficiency is a condition that affects the immune system (primary immunodeficiency). It causes recurring severe infections by a type of bacteria called pyogenic bacteria. 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 the IRAK4 gene and is inherited in an autosomal recessive pattern. Treatment may include intravenous immunoglobulin therapy (IVIG), taking antibiotics before an infection develops, and vaccines. Althought the infections can be life-threatening, they tend to occur less often as a person gets older.
