X-Linked Lymphoproliferative Syndrome

Also known as: X-linked lymphoproliferative disease, XLP, Duncan’s syndrome.

What is X-linked lymphoproliferative syndrome?

X-linked lymphoproliferative syndrome is a genetic disease in which the immune system does not work as well as it should. The greatest risk for children with X-linked lymphoproliferative syndrome seems to be from the Epstein-Barr virus, which causes mononucleosis. This virus can cause severe complications for children with X-linked lymphoproliferative syndrome.

What causes X-linked lymphoproliferative syndrome?

X-linked lymphoproliferative syndrome is caused by a genetic mutation. The disease is hereditary and can be passed along from parents to children.

What are the symptoms of X-linked lymphoproliferative syndrome?

Most people have no reaction or develop a mild illness in reaction to the Epstein-Barr virus. In people with X-linked lymphoproliferative syndrome, the immune system overreacts and causes a condition called hemophagocytic lymphohistiocytosis, which causes symptoms such as fever and severe organ damage. People with X-linked lymphoproliferative syndrome also have an increased risk of cancer.

What are X-linked lymphoproliferative syndrome care options?

Many people with X-linked lymphoproliferative syndrome are treated with immunoglobulin replacement therapy to help restore the immune system and reduce the risk of complications from the Epstein-Barr virus. Antibiotics and other medications can also play a role in preventing severe complications from the disease.

What is the Personalized Medicine Biobank?
The Nicklaus Children's Hospital biobank and tissue repository is an essential resource for personalized medicine research efforts, enabling the study of both health and disease over time. The Biobank collects samples and health information from volunteers, regardless of health history. Once a participant becomes part of the Biobank, he or she contributes to ongoing health research. We partner with Sanford Health, a national leader on specimen storage, management and integration with participant health information.
