A Novel COL3A1 c.2644G>T; p.(Gly882Cys) Variant in a Turkish Family with Vascular Ehlers-Danlos Syndrome.

Vascular Ehlers-Danlos syndrome (vEDS) is an autosomal dominant disease, also known as EDS type IV. The estimated prevalence for all EDS varies between 1/10,000 and 1/25,000 with EDS type IV representing approximately 5-10% of the cases. The vascular complications may affect all anatomical areas, with a tendency toward arteries of large and medium diameter. vEDS diagnosis is a challenging process. Patients usually have different phenotypic features and are unaware of the diagnosis at the time of initial vascular complications. The authors report the case of a 39-year-old male patient with EDS type IV, who developed internal carotid artery dissection and was diagnosed with clinical findings, imaging modalities, and a novel pathogenic COL3A1 variant.
