Fig. 1From: Next-generation sequencing and a novel COL3A1 mutation associated with vascular Ehlers–Danlos syndrome with severe intestinal involvement: a case reportSchematic representation of mature type III collagen fibers in: a wild type and b mutant case respectively. If there are mutations in one COL3A1 allele the dominant negative effect is a dramatic reduction in qualitative and quantitative production of COL3A1 protein. gDNA genomic DNA, mRNA messenger RNA, mut mutantBack to article page
