Research Abstract |
Vascular-type Ehlers-Danlos syndrome(vEDS) is a severe autosomal dominant inherited disorder resulting form mutations within theα1 typeIIIcollagen gene(COL3A1). Sequence analyses of the COL3A1 gene demonstrated heterozygous point mutations leading to glycine substitution in only nine patients(45%), while heterozygous splice-site mutations at the junction of the triple-helical exons were observed in the remaining 11 patients(55%). The average type III collagen production level in the cultured dermal fibroblasts was 14.6% of the normal value. The types of complication were not associated with specific mutations in COL3A1.
