Ehlers-Danlos syndrome-caused by mutations in the COL1A1 gene. Several mutations in the COL1A1 gene are responsible for the arthrochalasia type of Ehlers-Danlos syndrome. These genetic changes lead to the production of a pro-Î±1(I) chain that is missing a critical segment.ype I collagen is the most abundant form of collagen in the human body. The COL1A1 gene produces a component of type I collagen called the pro-Î±1(I) chain. Collagens begin as procollagen molecules, which must be processed by enzymes outside the cell to remove extra protein segments from their ends.
