A new COL3A1 mutation in Ehlers-Danlos syndrome type IV


Eder, Johanna; Laccone, Franco; Rohrbach, Marianne; Giunta, Cecilia; Aumayr, Klaus; Reichel, Christofer; Trautinger, Franz (2013). A new COL3A1 mutation in Ehlers-Danlos syndrome type IV. Experimental Dermatology, 22(3):231-234.

Abstract

The vascular type of the Ehlers-Danlos syndrome (Ehlers-Danlos syndrome type IV, EDS IV; OMIM #130050) is a rare connective tissue disorder with autosomal dominant transmission caused by mutations in the COL3A1 gene resulting in increased fragility of connective tissue with arterial, intestinal, and uterine ruptures and premature death. We present a 28-year-old female who in addition to typical EDS IV symptoms had severe peripheral artery occlusive disease (PAOD) and subtotal stenosis of the abdominal aorta. COL3A1 sequencing resulted in detection of an as yet undescribed mutation in exon 36 at position 2465 leading to a nucleotide replacement (c.2465G>C; p.G822A). Ultrastructural analysis of a skin biopsy revealed abnormal morphology and distribution of dermal collagen fibres. We conclude that PAOD is a possible manifestation of EDS IV and that further research is required to define its true prevalence among patients with EDS IV and its molecular pathology including genotype-phenotype correlation.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
