Collagen, type III, alpha 1 (Ehlers-Danlos syndrome type IV, autosomal dominant), also known as COL3A1, is a human gene.
This gene encodes a fibrillar collagen that is found in extensible connective tissues such as skin, lung, and the vascular system, frequently in association with type I collagen. Mutations in this gene are associated with Ehlers-Danlos syndrome type IV, and with aortic and arterial aneurysms. Although alternate transcripts have been detected for this gene, they are the result of mutations; these mutations alter splicing, often leading to the exclusion of multiple exons.
Type-III collagen is a fibrous scleroprotein in bone, cartilage, tendon, bone marrow stroma  and other connective tissue; yields gelatin on boiling.
Scleroprotein is a simple protein found in horny and cartilaginous tissues and in the lens of the eye.
