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 (Online ahead of print). doi: 10.1111/bjh.19748 .
