This syndrome has characteristics of hyperlaxity of the skin involving the entire body. It has been described in six patients. The phenotype is linked to a deficiency in vitamin K-dependent clotting factors and the syndrome has been associated with mutations in the GGCX gene. This gene encodes gamma-glutamyl carboxylase, an enzyme that has already been implicated in congenital vitamin K-dependent clotting factor deficiencies. This syndrome should be distinguished from pseudoxanthoma elasticum and cutis laxa in which the excessive skin folding is limited to specific zones.
