IgG and IgA monoclonal gammopathy of undetermined significance are precursor conditions of multiple myeloma; light-chain monoclonal gammopathy of undetermined significance of light-chain multiple myeloma; and IgM monoclonal gammopathy of undetermined significance of Waldenström’s macroglobulinemia and other Mar 14, 2014

The most common type of myeloma is IgG kappa. In IgG kappa myeloma, the myeloma cells produce an immunoglobulin made from two IgG heavy chains bound to two kappa light chains. About 15% of patients have light chain myeloma. In this type of myeloma, the myeloma cells secrete only light chain protein and no heavy chains.

Moreover, What is the treatment for monoclonal gammopathy?

No treatment is recommended for patients with MGUS. Long-term follow-up is generally advised, given the risk of progression to lymphoproliferative malignancy.
