Their mothers are not symptomatic, even though they are carriers of … 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. There are several classes of antibodies, and each one has a different function in the immune system. Durandy A. Hyper-IgM syndromes: a model for studying the regulation of class You know more about you, and your doctor knows more about medicine, so together you will work to find the best plan for you. Mutations in the CD40LG gene cause X-linked hyper IgM syndrome. Most infections are bacterial, but they can also be viral, Gastrointestinal issues, including diarrhea and difficulty absorbing nutrients from food (malabsorption), Pneumocystis jiroveci, an opportunistic form of pneumonia, in the first year of life, Susceptibility to cryptosporidium that may lead to disease of the liver, Low white blood cell count (neutropenia). Antibodies help protect the body against infection by attaching to specific foreign particles and germs, marking them for destruction. However, other forms of HIGM syndrome are inherited by both boys and girls as autosomal recessive traits. With over 400 types of primary immunodeficiency (PI), it’s important to know the basics. This condition is inherited in an X-linked recessive pattern. The molecular bases for some of the other forms of HIM have been discovered. This humoral immunodeficiency leads to recurrent sinopulmonary infections, chronic diarrhea due to Cryptosproidium infection, and neutropenia presenting within the first or second decade of life. 2007 May 31 [updated Serum Ig levels are measured; normal or elevated serum IgM levels and low levels or absence of other … US-NON-1397v2.0 09/20.

There are over 400 different types of PI, each with its own characteristics and challenges. In 1974, a World Health Organization (WHO) working party named the syndrome immunoglobulin deficiency with increased IgM (hyper-IgM syndrome [HIGM1]). This topic review discusses in detail only genetically determined forms of hyper-IgM syndrome. 2003 Nov;82(6):373-84. If blood tests show a normal or elevated level of IgM and low or absent IgG, with normal T cell and B cell numbers, genetic testing is needed. X-linked hyper IgM syndrome is a condition that affects the immune system and occurs almost exclusively in males. … How are genetic conditions treated or managed? Hyper-IgM Syndromes (HIGM) People with HIGM syndrome have normal or high levels of immunoglobulin M (IgM) in their blood, but reduced levels of other immunoglobulins, including IgG, IgA, and IgE. This gene provides instructions for making a protein called CD40 ligand, which is found on the surface of immune system cells known as T cells. Your healthcare team is there to provide recommendations based on you, and your situation. In: Adam MP, Ardinger HH, Pagon RA, Wallace SE, Bean LJH, Mirzaa G, Hyper-IgM syndrome is an immunoglobulin (Ig) deficiency characterized by normal or elevated serum IgM levels and decreased levels or absence of other serum immunoglobulins, resulting in susceptibility to bacterial infections. Affected individuals may develop autoimmune disorders, neurologic complications from brain and spinal cord (central nervous system) infections, liver disease, and gastrointestinal tumors. When CD40 ligand and its receptor protein are connected, they trigger a series of chemical signals that instruct the B cell to start making IgG, IgA, or IgE antibodies. HIGM syndrome is one of more than 400 different types of primary immunodeficiency (PI). More than 150 mutations in the CD40LG gene have been found to cause X-linked hyper IgM syndrome. Learn insights from those who have been there. The most common form of HIGM syndrome is passed along as an X-linked recessive trait (XHIGM) and is usually found only in boys. It's important to learn about the various treatments for PI, and should be individualized to meet your specific needs. Hyper IgM Syndrome is a very rare, one-in-a-million, and potentially life-threatening genetic mutation that severely compromises the immune system. CD40:CD40L interactions in X-linked and non-X-linked The affected individuals are virtually always male, because males only have one X chromosome, received from their mothers. 2007 Mar;20(3):133-41. For a discussion of genetic heterogeneity of immunodeficiency with hyper-IgM, see HIGM1 (308230). Thusberg J, Vihinen M. The structural basis of hyper IgM deficiency - CD40L Some conditions are caused by mutations in a single gene and can be inherited from one or both parents. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. Introduction The initial terminology of Hyper IgM Syndrome is really X-linked immunodeficiency with hyper– immunoglobulin M (XHIGM or HIGM1) is a rare form of primary immunodeficiency disease caused by mutations in the gene that codes for CD40 ligand (CD40L, also known as CD154 and gp39). HIGM1; Hyper-IgM syndrome 1; Immunodeficiency with Hyper-IgM, type 1 Common infections include pneumonia, sinus infections (sinusitis), and ear infections (otitis). Hyper-IgM syndrome is characterized by normal or high levels of immunoglobulin M (IgM) and decreased levels or absence of other immunoglobulins. T-cell effector function and post-thymic maturation in X-linked hyper-IgM Mutations in the CD40LG gene also impair the T cell's ability to differentiate and interact with other immune system cells. Diagnosis of hyper-IgM syndrome is suspected based on clinical criteria, including recurrent sinopulmonary infections, chronic diarrhea, and lymphoid hyperplasia. 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). Hyper IgM Syndrome Other forms of HIM syndrome are inherited as autosomal recessive traits and have been observed in females and males. Other Names for This Condition. If CD40 ligand does not attach to its receptor on B cells, these cells cannot produce IgG, IgA, or IgE antibodies. syndrome. 1997 Jul;131(1 Pt 1):47-54.

What is the prognosis of a genetic condition? Learn more. People with X-linked hyper IgM syndrome are more susceptible to infections because they do not have a properly functioning immune system. X-linked hyper-immunoglobulin M (IgM) syndrome is characterized by recurrent infections, low or undetectable levels of IgG and IgA, and normal to increased serum IgM, and [ncbi.nlm.nih.gov] Patients with hyper IgM syndrome generally have normal to elevated levels of IgM … Amemiya A, editors. Because it is X-linked, the disorder predominately affects males. People with this disorder have abnormal levels of proteins called antibodies or immunoglobulins. A PI diagnosis could be a total relief, or very overwhelming. Bhushan A, Covey LR. This imbalance can lead to recurrent and severe infections. Approximately 70% of people with hyper IgM syndrome inherit the disorder in an X-linked recessive pattern. Infections often cause these children to have chronic diarrhea and they fail to gain weight and grow at the expected rate (failure to thrive). Fasth A, Baer M, Gomez L, Sanders EA, Tabone MD, Plantaz D, Etzioni A, Monafo V, Immunological and genetic analysis of 65 patients with a clinical HIGM syndrome is genetic, and is usually passed down in one of two ways: Most children with HIGM syndrome will develop symptoms within the first or second year of life. 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). Hyper-IgM syndrome type 2 (HIGM2) is a rare immunodeficiency characterized by normal or elevated serum IgM levels with absence of IgG, IgA, and IgE, resulting in a profound susceptibility to bacterial infections. https://primaryimmune.org/.../specific-disease-types/hyper-igm-syndromes years of For the other 3 mutations, they run in an autosomal recessive manner, this is, the chances to have the condition is 25%, increasing if the parents are family between them. No patient was included who had only a positive family history of a lateral male relative with the hyper-IgM syndrome, since there are other forms of the hyper-IgM syndrome, 1 of which is inherited as an X-linked recessive trait 12,26,60 and 2 others that are inherited as autosomal recessive traits 17,30,40,47.

Hyper–Immunoglobulin M Syndrome Hyper-IgM syndrome (HIGM) is a descriptive term that reflects a common laboratory abnormality (high serum IgM level with low serum IgA and IgG levels) found in several otherwise dissimilar types of immunodeficiencies (Table 92-5). In severe cases, this is associated with mouth ulcers, inflammation, ulceration of the rectum, and skin infections, Increased likelihood to experience enlargement of the lymph nodes and the spleen. Members, For more connections, visit us on: Facebook. CD40 ligand is also important for other functions carried out by T-lymphocytes, so patients with X-linked hyper IgM syndrome (XHIM) have defective cellular immunity and are also susceptible to all kinds of infections, particularly opportunistic infections and to some types of cancer. Hyper IgM Syndrome 1. This kind of Hyper IgE syndrome is acquired by autosomal dominant inheritance whereby if one of the parents is affected, then chances of passing the abnormal gene to the child is about 50%.
