Ehlers-Danlos syndrome caused by the c.934C>T, p. Arg312Cys mutation in COL1A1 gene: an Italian family without cardiovascular events.

Classic Ehlers-Danlos syndrome (cEDS) is characterized by skin hyperelasticity, joint hypermobility, increased tendency to bruise, and abnormal scarring. Mutations in type V collagen, a regulator of type I collagen fibrillogenesis, underlie this type of EDS. In this article we report a genetic and clinical analysis of an Italian family that carried missense mutation c.934 C>T (p.R312C) in the COL1A1 gene. Literature review showed an association between this missense mutation and vascular complications. Genetic screening conducted on Italian family members, revealed that vascular events are absent. In conclusion, genetic and clinical data confirm the extreme heterogeneity of EDS. Nevertheless, vascular events could be a risk factor and periodical clinical evaluation could be relevant.
