Mitogen proliferation may be normal, but NK- and T-cell cytotoxicity can be impaired. Antigen-specific responses are usually decreased or absent. Total numbers of B cells are normal but there is a marked reduction of class-switched memory B cells. Defective oxidative burst of both neutrophils and macrophages has been reported. The range of clinical findings varies, even within the same family. More than 50% of males with HIGM1 develop symptoms by age one year, and more than 90% are symptomatic by age four years. HIGM1 usually presents in infancy with recurrent upper- and lower-respiratory tract bacterial infections, opportunistic infections including Pneumocystis jirovecii pneumonia, and recurrent or protracted diarrhea that can be infectious or noninfectious and is associated with failure to thrive. Neutropenia is common; thrombocytopenia and anemia are less commonly seen. Autoimmune and/or inflammatory disorders (such as sclerosing cholangitis) as well as increased risk for neoplasms have been reported as medical complications of this disorder. Significant neurologic complications, often the result of a CNS infection, are seen in 5%-15% of affected males. Liver disease, a serious complication of HIGM1 once observed in more than 80% of affected males by age 20 years, may be decreasing with adequate screening and treatment of Cryptosporidium infection." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1402" target="_blank">X-Linked Hyper IgM Syndrome</a></div><div>X-linked hyper IgM syndrome (HIGM1), a disorder of abnormal T- and B-cell function, is characterized by low serum concentrations of IgG, IgA, and IgE with normal or elevated serum concentrations of IgM. Mitogen proliferation may be normal, but NK- and T-cell cytotoxicity can be impaired. Antigen-specific responses are usually decreased or absent. Total numbers of B cells are normal but there is a marked reduction of class-switched memory B cells. Defective oxidative burst of both neutrophils and macrophages has been reported. The range of clinical findings varies, even within the same family. More than 50% of males with HIGM1 develop symptoms by age one year, and more than 90% are symptomatic by age four years. HIGM1 usually presents in infancy with recurrent upper- and lower-respiratory tract bacterial infections, opportunistic infections including Pneumocystis jirovecii pneumonia, and recurrent or protracted diarrhea that can be infectious or noninfectious and is associated with failure to thrive. Neutropenia is common; thrombocytopenia and anemia are less commonly seen. Autoimmune and/or inflammatory disorders (such as sclerosing cholangitis) as well as increased risk for neoplasms have been reported as medical complications of this disorder. Significant neurologic complications, often the result of a CNS infection, are seen in 5%-15% of affected males. Liver disease, a serious complication of HIGM1 once observed in more than 80% of affected males by age 20 years, may be decreasing with adequate screening and treatment of Cryptosporidium infection. [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/NBK1402#xlhi.Summary" target="NBK1402">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Diagnosis" target="NBK1402">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Clinical_Characteristics" target="NBK1402">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Genetically_Related_Allelic_Disorde" target="NBK1402">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Differential_Diagnosis" target="NBK1402">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Management" target="NBK1402">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Genetic_Counseling" target="NBK1402">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Resources" target="NBK1402">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Molecular_Genetics" target="NBK1402">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.Chapter_Notes" target="NBK1402">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1402#xlhi.References" target="NBK1402">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />HIGM is a rare immunodeficiency characterized by normal or elevated serum IgM levels associated with markedly decreased IgG, IgA, and IgE, resulting in a profound susceptibility to bacterial infections and an increased susceptibility to opportunistic infections. Patients with X-linked HIGM also tend to have neutropenia, as well as a high rate of gastrointestinal and central nervous system infections, often resulting in severe liver disease and/or neurodegeneration (summary by Levy et al., 1997).&#13;
Genetic Heterogeneity of Immunodeficiency with Hyper-IgM&#13;
Other forms of HIGM include HIGM2 (605258), which results from mutation in the AICDA gene (605257), HIGM3 (606843), which results from mutation in the CD40 gene (109535), and HIGM5 (608106), which results from mutation in the UNG gene (191525). See also HIGM4 (608184).  <a target="_blank" href="http://www.omim.org/entry/308230">http://www.omim.org/entry/308230</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />X-linked hyper IgM syndrome is a condition that affects the immune system and occurs almost exclusively in males. People with this disorder have abnormal levels of proteins called antibodies or immunoglobulins. Antibodies help protect the body against infection by attaching to specific foreign particles and germs, marking them for destruction. There are several classes of antibodies, and each one has a different function in the immune system. Although the name of this condition implies that affected individuals always have high levels of immunoglobulin M (IgM), some people have normal levels of this antibody. People with X-linked hyper IgM syndrome have low levels of three other classes of antibodies: immunoglobulin G (IgG), immunoglobulin A (IgA), and immunoglobulin E (IgE). The lack of certain antibody classes makes it difficult for people with this disorder to fight off infections.<br /><br />Individuals with X-linked hyper IgM syndrome begin to develop frequent infections in infancy and early childhood. Common infections include pneumonia, sinus infections (sinusitis), and ear infections (otitis). Infections often cause these children to have chronic diarrhea and they fail to gain weight and grow at the expected rate (failure to thrive). Some people with X-linked hyper IgM syndrome have low levels of white blood cells called neutrophils (neutropenia). Affected individuals may develop autoimmune disorders, neurologic complications from brain and spinal cord (central nervous system) infections, liver disease, and gastrointestinal tumors. They also have an increased risk of lymphoma, which is a cancer of immune system cells.<br /><br />The severity of X-linked hyper IgM syndrome varies among affected individuals, even among members of the same family. Without treatment, this condition can result in death during childhood or adolescence.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/x-linked-hyper-igm-syndrome">https://medlineplus.gov/genetics/condition/x-linked-hyper-igm-syndrome</a></div></div>
