Broader genetic screening has led to the growing recognition of the role of germline variants associated with adult bone marrow failure (BMF) and myeloid neoplasia (MN) not exclusively in children and young adults. In this study, we applied a germline variant panel to 3008 adult BMF and MN cases to assess the importance of germline genetics and its impact on disease phenotype and prognosis. In our cohort, up to 9.7% of BMF and 5.3% of MN cases carried germline variants. Our cohort also included heterozygous carriers of recessive traits, suggesting they contribute to the risk of BMF and MN. By gene category, variants of Fanconi anemia gene family represented the highest-frequency category for both BMF and MN cases, found in 4.9% and 1.7% cases, respectively. In addition, about 1.4% of BMF and 0.19% of MN cases harbored multiple germline variants affecting often functionally related genes as compound heterozygous. The burden of germline variants in BMF and MN was clearly associated with acquisition of monosomy 7. While BMF cases carrying germline variants showed similar overall survival as compared to the wild-type (WT) cases, MN cases with germline variants experienced a significantly shorter overall survival as compared to WT cases.
