Hematopoiesis, Pulmonary Embolism
Conditions
Keywords
Pulmonary Embolism, hematopoiesis, genetic sequencing, endothelial dysfunction
Brief summary
The clonal hematopoiesis of indetermined prognosis (CHIP) has been described as risk factor for juvenile atherosclerosis. Moreover, some of CHIP genes are responsible of myeloproliferative disorders. Venous thrombosis are frequent in these disorders. The purpose of this project is to determine if CHIP is frequent in unprovoked pulmonary embolism and could be part of the pathophysiology.
Interventions
Blood sample withdrawal in order to perform DNA sequencing

Eligibility
Inclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Variation of CHIP markers between patients groups | up to 2 years | Variation of CHIP markers (clonal hematopoiesis of indetermined prognosis ) between patients groups. CHIP concept have been defined as a mutation of preleukemic genes at an allelic variation inferior to 2% associated with normal complete blood count. |
