Enhancing the Clinical Management of CMF Through a National Pediatric and Adult Network Based on Biological and Genetic Data

A non-profit, translational, prospective and retrospective study. Patients will be enrolled according to the procedures described in the protocol, and samples will be processed and analyzed as specified in the protocol. Since constitutional bone marrow failure syndromes (CMF) are rare genetic disorders characterized by a variable and incompletely defined clinical phenotype, a partially unknown genetic etiology, and pathogenetic mechanisms that are only partly understood, we hypothesize that a number of patients currently diagnosed with idiopathic acquired aplastic anemia (AAA) or idiopathic single-lineage/multilineage bone marrow failure (BMF) may have been misdiagnosed and may actually have an underlying CMF. Therefore, our primary objective is to identify CMF underlying BMF and vice versa, by defining well-characterized patient cohorts based on clinical and family history, clinical
