Somatic compensation of inherited bone marrow failure
Inherited bone marrow failure syndromes (IBMFS) are a heterogeneous group of genetic disorders characterized by insufficient blood cell production and increased risk of transformation to myeloid malignancies. While genetically diverse, IBMFS are collectively defined by a cell-intrinsic hematopoietic stem cell (HSC) fitness defect that impairs HSC self-renewal and hematopoietic differentiation. In IBMFS, HSCs frequently acquire mutations that improve cell fitness, a phenomenon known as somatic compensation. Somatic compensation can occur via distinct genetic processes such as loss of the germline mutation or somatic alterations in pathways affected by the disease-causing gene. While the clinical implications of somatic compensation in IBMFS remain to be fully discovered, understanding these mutational processes can help understand disease pathophysiology and may inform future diagnostic and therapeutic approaches. In this review, we highlight current understanding about somatic compensation in IBMFS.
期刊介绍：
Seminars in Hematology aims to present subjects of current importance in clinical hematology, including related areas of oncology, hematopathology, and blood banking. The journal''s unique issue structure allows for a multi-faceted overview of a single topic via a curated selection of review articles, while also offering a variety of articles that present dynamic and front-line material immediately influencing the field. Seminars in Hematology is devoted to making the important and current work accessible, comprehensible, and valuable to the practicing physician, young investigator, clinical practitioners, and internists/paediatricians with strong interests in blood diseases. Seminars in Hematology publishes original research, reviews, short communications and mini- reviews.
