Immunology, hematology. Heavy chain disease is a form of paraproteinemia and plasma cell dyscrasia that involves the proliferation of cells producing immunoglobulin heavy chains. [1] This disease is characterized by an excessive production of heavy chains that are short and truncated. These heavy chain disease proteins have various deletions ...
The immunoglobulin heavy chain (IgH) is the large polypeptide subunit of an antibody (immunoglobulin). In human genome, the IgH gene loci are on chromosome 14. A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains. Several different types of heavy chain exist that define the class or isotype of an antibody.
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. [ 6 ] Often, no symptoms are noticed initially. [ 10 ] As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. [ 10 ]
Symptoms including blurring or loss of vision, headache, and (rarely) stroke or coma are due to the effects of the IgM paraprotein, which may cause autoimmune phenomena or cryoglobulinemia. Other symptoms of Waldenström macroglobulinemia are due to hyperviscosity syndrome, which is present in 6–20% of patients.
γ Heavy chain disease (also termed Franklin disease or Franklin's disease) presents in three patterns: a) aggressive lymphoma (57% to 66% of cases) associated with constitutional symptoms and in 50% of cases with enlargement of lymph nodes, spleen, and/or liver; b) localized lymphoma (~25% of cases) with lymphoma limited to the bone marrow or ...
The prefix "Ig" stands for immunoglobulin, while the suffix denotes the type of heavy chain the antibody contains: the heavy chain types α (alpha), γ (gamma), δ (delta), ε (epsilon), μ (mu) give rise to IgA, IgG, IgD, IgE, IgM, respectively. The distinctive features of each class are determined by the part of the heavy chain within the ...
Bortezomib-based management, Organ transplant. Monoclonal immunoglobulin deposition disease, or MIDD, is a disease characterised by the deposition of monoclonal immunoglobulins on the basement membrane of the kidney. Monoclonal immunoglobulins are produced by monoclonal plasma cells, which are found in a variety of plasma cell dyscrasias.
Approximately 40% of these mutations occur in the β-myosin heavy chain gene on chromosome 14 q11.2-3, and approximately 40% involve the cardiac myosin-binding protein C gene. Since HCM is typically an autosomal dominant trait, children of a single HCM parent have 50% chance of inheriting the disease-causing mutation.
