Cytogenetic abnormality in non-systemic light chain amyloidosis monoclonal gammopathy of renal significance: A field needs to be explored.

The role of cytogenetic abnormalities in non-systemic light chain amyloidosis monoclonal gammopathy of renal significance diseases still needs to be clarified. Bhutani et al. present the results of a study investigating the underlying plasma cell cytogenetic abnormalities in monoclonal immunoglobulin deposition disease (MIDD). The results show that translocation (11;14) is a common abnormality in MIDD and affects the presentation and outcomes. Commentary on: Bhutani et al. Translocation (11;14) is a common cytogenetic abnormality in clonal plasma cells in monoclonal immunoglobulin deposition disease. Br J Haematol 2024; 205:1860-1865.
