The condition primarily affects males. XLP has two recognizable subtypes, XLP1 (due to pathogenic variants in SH2D1A) and XLP2 (due to pathogenic variants in XIAP). HLH / fulminant infectious mononucleosis is the most common presentation regardless of subtype. HLH is characterized as an acute illness with prolonged and high fever, bi- or trilineage cytopenias, and hepatosplenomegaly, which is often severe or fatal. Death is generally secondary to liver failure or multisystem organ dysfunction. In those with XLP1, dys- or hypogammaglobulinemia can lead to varying degrees of humoral immune dysfunction associated with bronchiectasis and recurrent respiratory infections that, if untreated, may result in death. Lymphoproliferative disease (malignant lymphoma) and other lymphoproliferative diseases are specific to XLP1 and often develop in childhood, usually following EBV exposure. Rarer findings in those with XLP1 can include aplastic anemia, vasculitis, and lymphoid granulomatosis. Males with XLP2 are more likely to have HLH without EBV infection, recurrent episodes of HLH (which is not typically seen in those with XLP1), splenomegaly, and gastrointestinal disease, including enterocolitis and perirectal abscesses or fistulae. Rarely, individuals with XLP2 and inflammatory bowel disease have been reported to develop inflammatory liver disease, which can progress to fatal liver failure. Transient hypogammaglobulinemia has been rarely observed in those with XLP2. To date, neither lymphoproliferative disease nor common variable immunodeficiency has been reported in males with XLP2. Heterozygous females rarely have symptoms. There are, however, increasing numbers of reports of affected females with unfavorable (skewed) X-chromosome inactivation favoring the X chromosome with the pathogenic variant who develop HLH, inflammatory bowel disease, and erythema nodosum." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1406" target="_blank">X-Linked Lymphoproliferative Disease</a></div><div>X-linked lymphoproliferative disease (XLP) in general is characterized by an inappropriate immune response to Epstein-Barr virus (EBV) infection leading to hemophagocytic lymphohistiocytosis (HLH) or severe mononucleosis, dysgammaglobulinemia, and lymphoproliferative disease (malignant lymphoma). The condition primarily affects males. XLP has two recognizable subtypes, XLP1 (due to pathogenic variants in SH2D1A) and XLP2 (due to pathogenic variants in XIAP). HLH / fulminant infectious mononucleosis is the most common presentation regardless of subtype. HLH is characterized as an acute illness with prolonged and high fever, bi- or trilineage cytopenias, and hepatosplenomegaly, which is often severe or fatal. Death is generally secondary to liver failure or multisystem organ dysfunction. In those with XLP1, dys- or hypogammaglobulinemia can lead to varying degrees of humoral immune dysfunction associated with bronchiectasis and recurrent respiratory infections that, if untreated, may result in death. Lymphoproliferative disease (malignant lymphoma) and other lymphoproliferative diseases are specific to XLP1 and often develop in childhood, usually following EBV exposure. Rarer findings in those with XLP1 can include aplastic anemia, vasculitis, and lymphoid granulomatosis. Males with XLP2 are more likely to have HLH without EBV infection, recurrent episodes of HLH (which is not typically seen in those with XLP1), splenomegaly, and gastrointestinal disease, including enterocolitis and perirectal abscesses or fistulae. Rarely, individuals with XLP2 and inflammatory bowel disease have been reported to develop inflammatory liver disease, which can progress to fatal liver failure. Transient hypogammaglobulinemia has been rarely observed in those with XLP2. To date, neither lymphoproliferative disease nor common variable immunodeficiency has been reported in males with XLP2. Heterozygous females rarely have symptoms. There are, however, increasing numbers of reports of affected females with unfavorable (skewed) X-chromosome inactivation favoring the X chromosome with the pathogenic variant who develop HLH, inflammatory bowel disease, and erythema nodosum. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Summary" target="NBK1406">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Diagnosis" target="NBK1406">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Clinical_Characteristics" target="NBK1406">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Genetically_Related_Allelic_Disord" target="NBK1406">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Differential_Diagnosis" target="NBK1406">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Management" target="NBK1406">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Genetic_Counseling" target="NBK1406">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Resources" target="NBK1406">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Molecular_Genetics" target="NBK1406">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.Chapter_Notes" target="NBK1406">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1406#x-lpd.References" target="NBK1406">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />XLP2 is an X-linked primary immune deficiency with symptom onset usually in the first years of life, although later onset may occur. Features are compatible with immune dysregulation and include hemophagocytic lymphohistiocytosis (HLH), often associated with chronic Epstein-Barr virus (EBV) infection, splenomegaly, fever, colitis or inflammatory bowel disease (IBD), and recurrent infections. Laboratory abnormalities are variable, but can include hypogammaglobulinemia, cytopenias, and low levels of a particular subset of T cells known as NKT (or iNKT) cells. Functional studies show increased sensitivity of T cells to apoptosis (activation-induced cell death, AICD), impaired cytokine production, including of TNF-alpha (TNFA; 191160), and general dysregulation of the immune pathway, such as increased levels of IL18 (600953). However, circulating levels of lymphocytes and NK cells are usually normal. Many patients die from fulminant HLH, and the only curative treatment is a hematopoietic stem cell transplant, although this procedure has been associated with a poor prognosis. Female mutation carriers are usually asymptomatic, although some female carriers may have less severe manifestations, which appears to depend on X-inactivation patterns (summary by Yang et al., 2012; review by Latour and Aguilar, 2015).&#13;
Latour and Aguilar (2015) provided a detailed review of XIAP deficiency, including clinical features, molecular genetics, and pathophysiology.&#13;
For a general phenotypic description and a discussion of genetic heterogeneity of X-linked lymphoproliferative syndrome, see XLP1 (308240).  <a target="_blank" href="http://www.omim.org/entry/300635">http://www.omim.org/entry/300635</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />XLP can be divided into two types based on its genetic cause and pattern of signs and symptoms: XLP1 (also known as classic XLP) and XLP2. People with XLP2 have not been known to develop lymphoma, are more likely to develop hemophagocytic lymphohistiocytosis without EBV infection, usually have an enlarged spleen (splenomegaly), and may also have inflammation of the large intestine (colitis). Some researchers believe that these individuals should actually be considered to have a similar but separate disorder rather than a type of XLP.<br /><br />Without treatment, most people with XLP survive only into childhood. Death usually results from hemophagocytic lymphohistiocytosis.<br /><br />Cancers of immune system cells (lymphomas) occur in about one-third of people with XLP.<br /><br />About one-third of people with XLP experience dysgammaglobulinemia, which means they have abnormal levels of some types of antibodies. Antibodies (also known as immunoglobulins) are proteins that attach to specific foreign particles and germs, marking them for destruction. Individuals with dysgammaglobulinemia are prone to recurrent infections.<br /><br />People with XLP may respond to EBV infection by producing abnormally large numbers of T cells, B cells, and other lymphocytes called macrophages. This proliferation of immune cells often causes a life-threatening reaction called hemophagocytic lymphohistiocytosis. Hemophagocytic lymphohistiocytosis causes fever, destroys blood-producing cells in the bone marrow, and damages the liver. The spleen, heart, kidneys, and other organs and tissues may also be affected. In some individuals with XLP, hemophagocytic lymphohistiocytosis or related symptoms may occur without EBV infection.<br /><br />X-linked lymphoproliferative disease (XLP) is a disorder of the immune system and blood-forming cells that is found almost exclusively in males. More than half of individuals with this disorder experience an exaggerated immune response to the Epstein-Barr virus (EBV). EBV is a very common virus that eventually infects most humans. In some people it causes infectious mononucleosis (commonly known as "mono"). Normally, after initial infection, EBV remains in certain immune system cells (lymphocytes) called B cells. However, the virus is generally inactive (latent) because it is controlled by other lymphocytes called T cells that specifically target EBV-infected B cells.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/x-linked-lymphoproliferative-disease">https://medlineplus.gov/genetics/condition/x-linked-lymphoproliferative-disease</a></div></div>

<div class="spaceAbove">Ulcerative colitis is a chronic disorder that affects the digestive system. This condition is characterized by abnormal inflammation of the inner surface (epithelium) of the rectum and colon. The rectum and colon make up most of the length of the large intestine. The inflammation usually causes open sores (ulcers) to develop in the large intestine. Ulcerative colitis usually appears between the age of 15 and 30, although it can develop at any age. The inflammation tends to flare up multiple times throughout a person's life, which causes recurring signs and symptoms.\n\nThe most common symptoms of ulcerative colitis are cramping abdominal pain and frequent diarrhea, often with blood, pus, or mucus in the stool. Other signs and symptoms include nausea, loss of appetite, bowel urgency, fatigue, and fevers. Chronic bleeding from the inflamed and ulcerated intestinal tissue can cause a shortage of red blood cells (anemia) in some affected individuals. People with this disorder have difficulty absorbing enough fluids and nutrients from their diet and often experience weight loss. Affected children usually grow more slowly than normal. Less commonly, ulcerative colitis causes problems with the skin, joints, eyes, kidneys, or liver, which are most likely due to abnormal inflammation.\n\nToxic megacolon is a rare complication of ulcerative colitis that can be life-threatening. Toxic megacolon involves a widening (dilation) of the colon and an overwhelming inflammatory response. Ulcerative colitis also increases the risk of developing colon cancer, especially in people whose entire colon is inflamed and in those who have had ulcerative colitis for 8 years or more.\n\nUlcerative colitis is one common form of inflammatory bowel disease (IBD). Another type of IBD, Crohn's disease, also causes chronic inflammation of the intestines. Unlike ulcerative colitis, which affects only the inner surface of the large intestine, Crohn's disease can cause inflammation in any part of the digestive system, and the inflammation extends deeper into the intestinal tissue.</div>

<div class="spaceAbove">Aplastic anemia is a serious disorder of the bone marrow that affects between 2 and 5 persons per million per year. About 75% of these cases are classified as idiopathic (Young, 2000). In about 15% of cases a drug or infection can be identified that precipitates the aplasia, although why only some individuals are susceptible is unclear. In about 5 to 10% of patients, the aplastic anemia is constitutional--i.e., is familial or presents with one or more associated somatic abnormalities (summary by Vulliamy et al., 2002).</div>
