How I diagnose myeloid neoplasms with germline predisposition

Pdf Summary

The document emphasizes the significance of identifying germline predisposition to myeloid neoplasms for optimal disease management, genetic counseling, and stem cell donor screening. It stresses the importance of a comprehensive diagnostic approach involving clinical history, bone marrow findings, cytogenetics, and genetic testing. Case presentations illustrate challenging diagnostic scenarios and highlight specific genetic alterations associated with myeloid malignancies. The importance of genetic testing in confirming germline alterations is discussed, with caution needed in interpreting results from different tissue sources. The document underlines the complexity in detecting germline variants and limitations in current testing methods while stressing the need for careful interpretation and broader genetic testing if required. Additionally, it stresses the clinical implications of identifying germline alterations in myeloid neoplasms, especially in transplant situations. The text provides insights on when to recommend germline testing during bone marrow examinations and managing variants of uncertain significance. Clinical cases demonstrate the diagnostic challenges and the evolving understanding of germline predisposition to myeloid neoplasms, emphasizing the importance of interdisciplinary collaboration for accurate diagnosis and management. Ultimately, it highlights the necessity of integrating genetic testing into routine practice and recognizing distinct clinicopathologic features to improve patient care and outcomes in myeloid neoplasms.
