Short answer · Medically reviewed summary · Last updated: 2026-05-08
Agammaglobulinemia is a rare primary immunodeficiency disorder characterized by an almost complete absence of antibodies, historically and clinically referred to by several names including X-linked agammaglobulinemia (XLA) or Bruton’s agammaglobulinemia. While these terms are often used interchangeably in casual conversation, medical professionals currently prefer the term Agammaglobulinemia or X-linked agammaglobulinemia (when the genetic cause is confirmed) to accurately classify the condition in clinical practice. What are the common synonyms for Agammaglobulinemia? Because the understanding of immune function has evolved significantly over the last 70 years, Agammaglobulinemia has collected various names.

Agammaglobulinemia is a rare primary immunodeficiency disorder characterized by an almost complete absence of antibodies, historically and clinically referred to by several names including X-linked agammaglobulinemia (XLA) or Bruton’s agammaglobulinemia. While these terms are often used interchangeably in casual conversation, medical professionals currently prefer the term Agammaglobulinemia or X-linked agammaglobulinemia (when the genetic cause is confirmed) to accurately classify the condition in clinical practice.
What are the common synonyms for Agammaglobulinemia?
Because the understanding of immune function has evolved significantly over the last 70 years, Agammaglobulinemia has collected various names. The most common synonym is Bruton’s agammaglobulinemia, named after Dr. Ogden Bruton, who first described the condition in 1952. Other terms you may encounter in medical records or historical literature include:
- X-linked agammaglobulinemia (XLA)
- Bruton-type agammaglobulinemia
- Congenital agammaglobulinemia
- Hypogammaglobulinemia (though this is technically a broader category)
- BTK deficiency (referring to the specific gene mutation)
Why does Agammaglobulinemia have so many names?
The variety of names for Agammaglobulinemia arises from the transition from descriptive naming (based on symptoms like low gamma-globulin levels) to genetic naming (based on the identification of the BTK gene). Historical literature often uses "Bruton's disease," while modern genetic databases classify it by the specific molecular defect. This reclassification ensures that clinicians can distinguish between X-linked forms and rarer autosomal recessive forms of Agammaglobulinemia.
How is Agammaglobulinemia classified officially?
Major medical organizations utilize specific codes to ensure consistency in research and care. You will typically find the condition listed in the following systems:
- Orphanet: Classified as ORPHA:39 (X-linked agammaglobulinemia).
- OMIM: Listed under #300755 (Agammaglobulinemia, X-linked).
- ICD-10/11: Coded under D80.0 (Congenital hypogammaglobulinemia).
