详细说明
The preDDX registry aims to study germline genetic predispositions to myeloid neoplasms, in particular those associated with pathogenic DDX41 variants and emerging syndromes.
It includes patients and, where applicable, their relatives, with prospective collection of clinical, biological and genetic data.
It is a Category 2 Research Involving the Human Person (RIPH2), based mainly on data from routine care, with no imposed therapeutic intervention. Additional procedures with minimal risks and constraints may be performed if necessary.
The data collected will help to better characterize these predispositions and their evolution in real-world practice.
