Monoclonal Gammopathy

Monoclonal gammopathy refers to the abnormal production of a specific type of protein, called a monoclonal protein or M protein, by a single type of immune cell.

Monoclonal gammopathy is a medical term for the abnormal production of a single type (or clone) of an immune system protein called a gamma globulin. In simple words, the body produces too much of a single type of protein and not enough of the other necessary types.

Types:

  1. MGUS (Monoclonal Gammopathy of Undetermined Significance): A condition where M protein is present, but there are no symptoms or disease.
  2. MM (Multiple Myeloma): A cancer where bone marrow makes too many plasma cells.
  3. Plasmacytoma: A single tumor of abnormal plasma cells.
  4. Lymphoma: Cancer of the lymph nodes that can produce M protein.
  5. Amyloidosis: A disease where abnormal proteins build up in organs and tissues.

or

  1. MGUS (Monoclonal Gammopathy of Undetermined Significance): The most common type. This has a small risk of progressing to serious conditions.
  2. Smoldering Multiple Myeloma (SMM): Higher protein levels than MGUS but not severe enough to be multiple myeloma.
  3. Multiple Myeloma: A type of cancer where bone marrow makes too many plasma cells (a type of white blood cell).
  4. Waldenström Macroglobulinemia: Rare. A cancer involving large amounts of an antibody called IgM.
  5. AL Amyloidosis: Abnormal proteins build up in organs causing damage.

Causes:

  1. Age: Older adults are more likely.
  2. Male gender: Men are at a slightly higher risk.
  3. Race: More common in Black people than White.
  4. Family history: Risk increases if family members had it.
  5. Chemical exposure: Pesticides and herbicides might increase risk.
  6. Radiation: Exposure might raise the risk.
  7. Viruses: Certain viruses may play a role.
  8. Autoimmune disorders: Diseases where body attacks itself.
  9. Kidney disease: Some kidney problems increase the risk.
  10. Obesity: Being very overweight can play a role.
  11. Bone marrow conditions: Diseases affecting bone marrow.
