Living with Immunodeficiency 67

An inherited immune condition causing repeated serious infections with certain bacteria, mostly in early childhood.

Understanding Immunodeficiency 67

Immunodeficiency 67, also called IRAK-4 deficiency, is an inherited immune system disorder with repeated infections by pus-forming (pyogenic) bacteria.

It does not cause repeated infections by other kinds of germs. Most people have a first bacterial infection before age 2, and infections become less frequent with age. Infections can involve the blood, the covering of the brain and spinal cord, or the joints. Many people don't develop a high fever at first, even with severe infection.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Repeated bacterial infections
  • Repeated skin infections
  • Repeated Staphylococcus infections
  • Repeated Streptococcus pneumoniae infections
  • Low neutrophil (white blood cell) count
  • Weakened immune function

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include allergy and immune system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in IRAK4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Immune Deficiency Foundation may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Recessive
GenesIRAK4

Changes in the IRAK4 gene cause this condition. It is inherited in an autosomal recessive pattern, meaning a child inherits a changed copy of the gene from each parent.
