Preferred Label : Lymphoproliferative syndrome 1;
Symbol : LPFS1;
CISMeF acronym : LPFS1;
Type : Phenotype, molecular basis known;
Description : 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).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the IL2-inducible T-cell kinase gene (ITK, 186973.0001);
Neoplasia : Increased risk for lymphoma Hodgkin disease;
Laboratory abnormalities : Elevated erythrocyte sedimentation rate (ESR); Increased C-reactive protein; High EBV viral load;
