Living with Autosomal agammaglobulinemia

A rare immune condition with very low antibody levels, causing frequent bacterial infections starting around 6 months of age.

Understanding Autosomal agammaglobulinemia

Autosomal agammaglobulinemia is a rare form of agammaglobulinemia, a primary immune condition with very low levels of immunoglobulins (infection-fighting proteins).

People generally begin having frequent, repeated bacterial infections from about 6 months of age. These include lung infections, ear infections, pink eye, sinus infections, skin infections, and infections with chronic diarrhea.

Signs & symptoms

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

  • Repeated infections
  • Ear and sinus infections
  • Lung infections with cough
  • Skin infections and rashes
  • Diarrhea and poor weight gain
  • Fever and tiredness

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. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

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

Quick facts

InheritanceAutosomal Dominant, Autosomal Recessive

GARD says it can be caused by changes in many genes, including IGHM, IGLL1, CD79A, CD79B, BLNK, PIK3R1, and TCF3. It is usually autosomal recessive, though some families have a dominant pattern.
