Monoclonal gammopathy of renal significance (MGRS) is a recently defined entity. It is a group of renal diseases due to paraprotein deposition from a small B lymphocyte or plasma cell clon, not meeting the criteria for an overt gammopathy-associated neoplasm. Despite this feature, the secondary kidney damage may be severe and irreversible; therefore, its early recognition and treatment are crucial. There are few studies on MGRS in the international literature, and no reported data from Latin America (LA).
