Living with DDX41-related hematologic malignancy predisposition syndrome

A rare inherited condition that raises the chance of certain blood cancers in adulthood.

Understanding DDX41-related hematologic malignancy predisposition syndrome

DDX41-related hematologic malignancy predisposition syndrome is a rare inherited condition that makes certain blood cancers more likely in adults.

The cancers mainly affect myeloid cells, a type of blood cell. They include myelodysplastic syndrome and acute myeloid leukemia. Some people also develop immune-related problems such as sarcoidosis, lupus, asthma, eczema, or juvenile arthritis, sometimes before or without a blood cancer.
