Learn More About X-Linked Lymphoproliferative Disease

One of the first steps after an X-linked lymphoproliferative (XLP) disease diagnosis is understanding the condition. Diplomat is here to help.

But remember: The information here — and on linked sites — is not meant to replace advice, care, or a diagnosis from your physician. If you have questions about your condition, please ask your provider.


X-linked lymphoproliferative disease is a genetic condition characterized by a defective immune system. It occurs in about one in a million males worldwide. Although XLP is genetic, it might not be diagnosed until well into childhood. Symptoms typically occur in response to an episode of Epstein-Barr virus (EBV), a common disease in the herpesvirus family that will affect most people in their lifetime.

As a patient responds to EBV, their body will create an overabundance of immune cells. This potentially fatal reaction can trigger hemophagocytic lymphohistiocytosis (HLH), a life-threatening condition. The HLH reaction puts the patient at risk for hepatitis and lymphoma after exposure to EBV.

XLP causes no symptoms until a patient is infected with EBV, though blood tests might show it. Treatment with immunoglobulin G (IgG), with or without antibodies to EBV, can help prevent or treat the infection.
