SUMMARY

Monoclonal gammopathy of renal significance (MGRS) represents a heterogeneous group of diseases in which a monoclonal immunoglobulin, secreted by a plasma or B-cell clone with no evidence of malignancy, causes renal damage. As MGRS patients have a high risk of developing permanent kidney damage, adequate diagnosis and treatment are required to preserve kidney function. In this review, we address the definition, mechanisms and classification of MGRS, and discuss how patients with suspected MGRS should be evaluated and managed.
