The study hypothesis is the involvement of the couple CX3CR1/CX3CL1 in occurrence of endothelial injury in preeclampsia. According to this hypothesis, Carriers of the I249 allele who express less CX3CR1 shoud be protected against this risk. The main objective of the study is the search of an association between CX3CR1 V249I polymorphism and preeclampsia. The secondary aims are the search of an association with the most severe forms of preeclampsia and endothelial injury.

Detailed Description:

It is a case-control multicenter study 185 caucasian pregnant women with preeclampsia and 185 paired controls without preeclampsia will be included.

The frequency of the V249I polymorphism in african black population will be determined by studying 200 subjects (100 cases and 100 controls).

The V249I polymorphism will be identified by PCR followed by enzyme digestion. Endothelial injury will be identified using three assays : von Willebrand factor, soluble VCAM-1 and thrombomodulin plasma levels.

CX3CR1 involvement in preeclampsia would have potential diagnostic and therapeutic consequences.
