Definition

Lymphoproliferative syndrome-1 is an autosomal recessive primary immunodeficiency characterized by onset in early childhood of Epstein-Barr virus (EBV)-associated immune dysregulation, manifest as lymphoma, lymphomatoid granulomatosis, hemophagocytic lymphohistiocytosis, Hodgkin disease, and/or hypogammaglobulinemia. Autoimmune disorders, such as autoimmune hemolytic anemia or renal disease, may also occur. Patients show a high EBV viral load and decreased invariant natural killer T cells. It is unknown whether patients with ITK mutations are intrinsically susceptible to development of lymphoma or dysgammaglobulinemia in the absence of EBV infection (summary by Stepensky et al., 2011; Linka et al., 2012). For a discussion of genetic heterogeneity of lymphoproliferative syndrome, see XLP1 (308240). [from OMIM]

Clinical features

From HPO
Classic Hodgkin lymphoma
MedGen UID:
9283
Concept ID:
C0019829
Neoplastic Process
Classic Hodgkin lymphoma is a lymph node cancer of germinal center B-cell origin. Hodgkin lymphoma tumors consist of a minority of malignant cells, known as 'Reed-Sternberg' (RS) cells, mixed with reactive lymphocytes and other benign inflammatory cells. A defining feature of RS cells is the presence of 2 nuclei (summary by Salipante et al., 2009).
Lymphoproliferative disorder
MedGen UID:
6162
Concept ID:
C0024314
Neoplastic Process
A disorder characterized by proliferation of lymphocytes at various stages of differentiation. Lymphoproliferative disorders can be neoplastic (clonal, as in lymphomas and leukemias) or reactive (polyclonal, as in infectious mononucleosis).
B-cell lymphoma
MedGen UID:
86953
Concept ID:

Leukopenia
MedGen UID:
6073
Concept ID:
C0023530
Disease or Syndrome
An abnormal decreased number of leukocytes in the blood.
Splenomegaly
MedGen UID:
52469
Concept ID:
C0038002
Finding
Abnormal increased size of the spleen.
Stomatitis
MedGen UID:

Disease or Syndrome
Phagocytosis by macrophages of erythrocytes, leukocytes, platelets, and their precursors in bone marrow and other tissues.
Persistent EBV viremia
MedGen UID:
767466
Concept ID:
C3554552
Finding
Persistent presence of Epstein-Barr virus in the blood.
Decreased circulating antibody level
MedGen UID:
892481
Concept ID:
C4048270
Finding
An abnormally decreased level of immunoglobulin in blood.
Decreased circulating IgG level
MedGen UID:
1720114
Concept ID:
C5234937
Finding
An abnormally decreased level of immunoglobulin G (IgG) in blood.
Decreased proportion of CD4-positive helper T cells
MedGen UID:
1719772
Concept ID:
C5235140
Finding
A decreased proportion of circulating CD4-positive helper T cells relative to total T cell count.
Elevated erythrocyte sedimentation rate
MedGen UID:
57727
Concept ID:
C0151632
Finding
An increased erythrocyte sedimentation rate (ESR). The ESR is a test that measures the distance that erythrocytes have fallen after one hour in a vertical column of anticoagulated blood under the influence of gravity. The ESR is a nonspecific finding. An elevation may indicate inflammation or may be caused by any condition that elevates fibrinogen.
Increased circulating ferritin concentration
MedGen UID:
69130
Concept ID:
C0241013
Finding
Increased concentration of ferritin in the blood circulation.
Recurrent fever
MedGen UID:
811468
Concept ID:
C3714772
Sign or Symptom
Periodic (episodic or recurrent) bouts of fever.
Elevated circulating C-reactive protein concentration
MedGen UID:
892906
Concept ID:
C4023452
Finding
An abnormal elevation of the C-reactive protein level in the blood circulation.
