Description : X-linked lymphoproliferative syndrome, or Duncan disease, is a primary immunodeficiency
characterized by severe immune dysregulation often after viral infection, typically
with Epstein-Barr virus (EBV). It is a complex phenotype manifest as severe or fatal
mononucleosis, acquired hypogammaglobulinema, hemophagocytic lymphohistiocytosis (HLH),
and/or malignant lymphoma. Other features may include aplastic anemia, red cell aplasia,
and lymphomatoid granulomatosis (Purtilo et al., 1977; Purtilo, 1981; Purtilo and
Grierson, 1991; Coffey et al., 1998; Booth et al., 2011). - Genetic Heterogeneity
of X-linked/Autosomal Lymphoproliferative Syndrome See XLP2 (300635), caused by mutation
in the XIAP gene (300079) also on Xq25; LPFS1 (613011), caused by mutation in the
ITK gene (186973) on chromosome 5q32; and LPFS2 (615122), caused by mutation in the
CD27 gene (186711) on chromosome 12p13.;
Inheritance : X-linked recessive;
Molecular basis : Caused by mutations in the SH2 domain protein 1A gene (SH2D1A, 300490.0001);
Neoplasia : Hemophagocytic lymphohistiocytosis; Lymphoma;
Laboratory abnormalities : Increased IgM levels; Reduced IgG levels;
