NCT04477564

Brief Summary

The aim of the study is to investigate the existence of clonal hematopoiesis of indeterminate potential (CHIP) in patients with a history of venous thromboembolism. The study investigators make the assumption that these patients present mutations involved in CHIP occurrence.

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Men and women over 50 years old who have consulted at the Hematology laboratory of the Nîmes University Hospital for the occurrence or history of venous thromboembolism (Distal/proximal; Provoked/unprovoked) and who has accepted that their DNA was kept and used in the context of research on venous thromboembolism

You may qualify if:

  • Men and women over 50 years old who have consulted at the Hematology laboratory of the Nîmes University Hospital for the occurrence or history of venous thromboembolism
  • Patient who has accepted that their DNA was kept and used in the context of research on venous thromboembolism (biobank (registration number DC-2008-290 and authorization number AC-2008-107))

You may not qualify if:

  • Patients less than 50 years old
  • Patient who has refused that their DNA was kept and used in the context of research on venous thromboembolism
