We understand the unique needs of patients and the challenges of dealing with infections, autoimmune issues and prescription regimens that can often be complicated.

We uncover funding options, answer questions 24/7 and communicate thoroughly to keep the entire health care team on the same page.

X-Linked Agammaglobulinemia

One of the first steps after an X-linked agammaglobulinemia (XLA) diagnosis is understanding the condition. The information on this site and linked sites is not meant to replace your physician’s advice, medical care or a diagnosis. If you have questions about your disease, please ask your prescriber.


X-linked agammaglobulinemia, also known as Bruton agammaglobulinemia, is caused by a mutation in a gene found in the X chromosome. This mutation affects the ability of the body to fight infections. Because it is an X-linked mutation, XLA mostly affects boys.

Symptoms often start around six months in age. As protective antibodies from the infant’s mother wear off, patients with XLA are unable to produce enough B cells, compromising the body’s ability to fight infection. In rare cases, symptoms might not occur until the patient is a teenager.

XLA is extremely rare, occurring in only one in 200,000 newborns. Children with XLA might cope well with short-term viral infections but are susceptible to chronic viral infections such as hepatitis and polio. Common bacterial infections in XLA patients include ear infections, pink eye, pneumonia, sinus infections and other infections causing diarrhea.

Regular immune globulin treatment can offer XLA patients the antibodies crucial to their health.
