Abnormal type III collagen produced by an exon-17-skipping mutation of the COL3A1 gene in Ehlers-Danlos syndrome type IV is not incorporated into the extracellular matrix.

Abstract excerpt

A novel heterozygous mutation of the COL3A1 gene that encodes the alpha 1(III) chains of type III collagen was identified in a family with the acrogeric form of Ehlers-Danlos syndrome type IV (EDS-IV). Cultured dermal fibroblasts produced normal and shortened alpha 1(III) chains. The triple helix of the latter chain was shortened owing to a 33 amino acid deletion of Gly-184 to Pro-216. The corresponding region of...
