Ghosal hematodiaphyseal dysplasia (GHDD) is an autosomal recessive disorder characterized by increased bone density with predominant diaphyseal involvement and aregenerative corticosteroid-sensitive anemia (summary by Genevieve et al., 2008).

DDX41-associated familial myelodysplastic syndrome and acute myeloid leukemia (MDS/AML) is characterized by an increased risk of myeloid neoplasms, lymphoid neoplasms, adult-onset single- or multiple-lineage cytopenias (including aplastic anemia), and red blood cell macrocytosis. The most common myeloid neoplasms include MDS, AML, and therapy-related myeloid neoplasms. Chronic myelomonocytic leukemia, chronic myeloid leukemia, and myeloproliferative neoplasms are less common. Lymphoid neoplasms include non-Hodgkin lymphoma, Hodgkin lymphoma, multiple myeloma, chronic lymphocytic leukemia, and acute lymphoblastic leukemia.
