Purpose: Identification of the gene(s) involved in plasma membrane remodelling. Identification of the circulating markers affected by the defective membrane remodelling in a collection of families with unexplained provoked hemorrhages and evaluation of their prognosis value in the assessment of the hemostatic cellular response.Hypothesis: Scott syndrome is rare a familial disorder characterized by provoked haemorrages in homozygous-type patients due to isolated membrane remodelling deficiency. Membrane remodelling is necessary for cellular hemostatic responses.

Condition Intervention
Unexplained Isolated Provoked Hemorrhages

Study Population

Patients with unexplained bleeding disorder


Inclusion Criteria:

  • Patients with unexplained provoked hemorrhages (surgery, tooth extraction, birth …), and associated with reduced prothrombin consomption (residual prothrombine in serum > à 5%).
  • Family members of the patients defined above, with or without unexplained hemorrhages (symptomatic or not).
  • Patient's approval based on detailed information given by the pratician

Exclusion Criteria:

  • Patients with primary hemostasis defect or defective blood coagulation factor(s) possibly explaining the bleeding disorder.
  • Anémia,
  • patients known to be affected by Factor V New York .
  • Patients enrolled in a previous clinical study, the exclusion period of which is not yet completed. - Collaboration to the study rejected by the patient
  • Patients that are not registered for medical care social insurance.
