abstract = {Individuals with germline variants associated with
hereditary hematopoietic malignancies (HHMs) have a highly
variable risk for leukemogenesis. Gaps in our understanding
of pre-malignant states in HHMs have hampered efforts to
design effective clinical surveillance programs, provide
personalized pre-emptive treatments and inform appropriate
counselling for patients. We used the largest known
comparative international cohort of germline RUNX1, GATA2,
or DDX41 variant carriers without and with hematopoietic
malignancies (HMs) to identify patterns of genetic drivers
that are unique to each HHM syndrome before and after
leukemogenesis. These patterns included striking
heterogeneity in rates of early-onset clonal hematopoiesis
(CH), with a high prevalence of CH in RUNX1 and GATA2
variant carriers who did not have malignancies
('carriers-without HM'). We observed a paucity of CH in
DDX41 carriers-without HM. In RUNX1 carriers-without HM with
CH, we detected variants in TET2, PHF6, and, most
frequently, BCOR. These genes were recurrently mutated in
RUNX1-driven malignancies, suggesting CH is a direct
precursor to malignancy in RUNX1-driven HHMs. Leukemogenesis
in RUNX1 and DDX41 carriers was often driven by second-hits
in RUNX1 and DDX41, respectively. This study may inform the
development of HHM-specific clinical trials and
gene-specific approaches to clinical monitoring. For
example, trials investigating the potential benefits of
monitoring DDX41 carriers-without HM for low-frequency
second hits in DDX41 may now be beneficial. Similarly,
trials monitoring carriers-without HM with RUNX1 germline
variants for the acquisition of somatic variants in BCOR,
PHF6, TET2, and second hits in RUNX1 are warranted.},
