Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The existence of a family factor in the genesis of varicose veins is certain, but few studies have addressed reliably instead of the genetic factor in clinical and molecular level. The investigator initiated an original study to identify one or more genetic abnormalities predisposing to varicose disease, based on a combined approach of genetic linkage and of exome sequencing. The clinical research phase is an essential prerequisite to the identification of genetic mutations; it is to identify large affected families and ensure an extremely rigorous and accurate phenotyping of individuals over several generations. A first clinical work has identified and / or phenotype 8 families with a genetically informative family suggesting autosomal dominant inheritance. Linkage analysis suggested several candidate chromosomal regions without allowing the identification of a gene. This project aims to resume and expand the Family clinical investigations and apply the techniques of genome analysis points, including exome sequencing on the most informative families to identify the genes and mechanisms responsible of this disease and improve the prevention and the treatment of varicose veins.
