Low levels of serum type III procollagen aminoterminal propeptide confirmed type III collagen deficiency in patients without typical clinical symptoms of Ehlers‐Danlos type IV

Abstract. Biochemical analysis of skin samples revealed that the content of type III collagen was greatly reduced in several subjects with joint hyper‐mobility, stretchability and bruisability of skin. When cultured dermal fibroblasts were found to secrete decreased amounts of type III procollagen into medium (about 30–45% the normal amount) and serum type III procollagen aminopropeptide levels were significantly lower than normal values (P < 0.001).
