Familial clusters of leukemia led to the identification of germline variants associated with lymphoid neoplasms (PAX5, IKZF1, SH2B3, and ARID2), myeloid neoplasms (RUNX1, GATA2, CEBPA, DDX41, ANKRD26, ETV6, and TP53), and inherited bone marrow syndromes (GATA2, TERC, TERT, FANCA, and FANCB) (31). The gene discussed is DDX41; the disease is myeloid neoplasm.
