DESCRIPTION (provided by applicant): The inherited bone marrow failure and myelodysplastic syndromes (iBMF/MDS) are a heterogeneous group of disorders that are characterized by impaired hematopoiesis and a propensity to progress to leukemia. Despite recent advances in the field, a significant percentage of patients presenting with inherited marrow failure or MDS do not fall into the known diagnostic categories and remain idiopathic. Since many of these genetic syndromes entail specific management and treatment considerations that differ significantly from standard therapies used for acquired marrow failure/MDS, accurate diagnosis is essential. This is a resource development and gene discovery grant investigating iBMF/MDS to characterize their phenotypic spectrum, to develop novel imaging modalities for bone marrow pathology, and to gain insights into the genetic and molecular mechanisms regulating hematopoiesis and marrow failure. We will apply cutting edge genomics approaches to samples from comprehensively phenotyped children and adults to identify new genes responsible for iBMF/MDS. This project will also investigate the clinical and biological consequences of somatically acquired genetic mutations on disease progression and prognosis in iBMF/MDS and determine the similarities or differences in genetic landscapes between inherited versus acquired marrow failure/MDS. We will also interrogate seemingly sporadic marrow failure or MDS presenting in the general population for cryptic presentations of inherited disorders. Resources generated for the broader clinical and scientific communities will include high-throughput multiplexed gene analysis platforms for iBMF/MDS, evidence- based algorithms for the diagnostic workup and management of iBMF/MDS, centralized hematopathology review, and comprehensively clinically annotated biological samples for further investigation. This project should yield new insights into blood cell development and the molecular pathogenesis of marrow failure and MDS; will advance the development of new diagnostic tests, therapies and biomarkers for marrow failure and MDS; will provide clinical resources forthe hematology community; and will provide new tools and methods for future studies ofthe molecular pathways regulating hematopoiesis.

描述（由申请人提供）：遗传的骨髓衰竭和骨髓增生综合征（IBMF/MDS）是一组异质性疾病，其特征是造血受损，并且倾向于促进白血病。尽管该领域最近取得了进步，但在遗传骨髓衰竭或MD的患者中，很大一部分并不属于已知的诊断类别，并且仍然保持特发性。由于这些遗传综合症中的许多都需要特定的管理和治疗考虑因素，这些因素与用于获得的骨髓衰竭/M​​D的标准疗法显着不同，因此准确的诊断至关重要。这是研究IBMF/MD的资源开发和基因发现赠款，以表征其表型谱，开发出新的成像骨髓病理学的成像方式，并深入了解调节造血和骨髓衰竭的遗传和分子机制。我们将对来自全面表型儿童和成人的样本应用最前沿的基因组学方法，以鉴定负责IBMF/MD的新基因。该项目还将调查IBMF/MDS中遗传突变对疾病进展和预后的临床和生物学后果，并确定遗传景观与获得的骨髓衰竭/M​​D之间的遗传景观的相似性或差异。我们还将询问看似零星的骨髓衰竭或在普通人群中呈现的MD，以表现出遗传性疾病的神秘表现。为更广泛的临床和科学社区生成的资源将包括用于IBMF/MD的高通量多路复用基因分析平台，基于证据的算法，用于IBMF/MDS的诊断工作和管理，集中的血液病理学评论，以及全面的临床临床生物学样本。该项目应为血细胞发育以及骨髓衰竭和MD的分子发病机理提供新的见解。将推动开发新的诊断测试，疗法和生物标志物，用于骨髓衰竭和MDS；将为血液学社区提供临床资源；并将为调节造血的分子途径提供新的工具和方法。
