Subclasses IgG1--IgG4 in 84 sera with IgG paraprotein. 1978

M Tichý, and Z Hrncír, and J Mracek

The distribution of subclasses IgG1-4 was determined in 84 sera with IgG paraprotein. The results were as follows: IgG1--58.3%, IgG2--25%, IgG3--11.9%, IgG4--4.8%. After division into the group of IgG myelomas (n = 47) and the group of non-myeloma IgG paraproteinemias (n = 37), the following distribution was found: IgG1--55.3%, IgG2--25.5%, IgG3--12.7%, IgG4--6.5% and IgG1--62.1%, IgG2--24.3%, IgG3--10.8%, IgG4--2.7%, respectively. The distribution of light chains in the individual subclasses of IgG paraproteins was also studied. In three double IgG and IgA myeloma paraproteinemias, subclass 1 IgG paraprotein was always demonstrated.

UI	MeSH Term	Description	Entries
D007070	Immunoglobulin A	Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions.	IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA
D007074	Immunoglobulin G	The major immunoglobulin isotype class in normal human serum. There are several isotype subclasses of IgG, for example, IgG1, IgG2A, and IgG2B.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009101	Multiple Myeloma	A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.

D009194	Myeloma Proteins	Abnormal immunoglobulins characteristic of MULTIPLE MYELOMA.	M Components,Proteins, Myeloma
D010265	Paraproteinemias	A group of related diseases characterized by an unbalanced or disproportionate proliferation of immunoglobulin-producing cells, usually from a single clone. These cells frequently secrete a structurally homogeneous immunoglobulin (M-component) and/or an abnormal immunoglobulin.

D010266	Paraproteins	Abnormal immunoglobulins synthesized by atypical cells of the MONONUCLEAR PHAGOCYTE SYSTEM. Paraproteins containing only light chains lead to Bence Jones paraproteinemia, while the presence of only atypical heavy chains leads to heavy chain disease. Most of the paraproteins show themselves as an M-component (monoclonal gammopathy) in electrophoresis. Diclonal and polyclonal paraproteins are much less frequently encountered.	Paraprotein
