title: Sclerosis of the skin in the GEMSS syndrome. An overproduction of normal collagen.
abstract: BACKGROUND
  We describe a recently observed set of autosomal dominant GEMSS (glaucoma, lens ectopia, microspherophakia, stiffness of the joints, and shortness) syndrome in a 47-year-old woman and her 23-year-old son. In addition, sclerosis of the skin, from which both patients suffered, is investigated in detail.
  
  
  METHODS
  The histologic examination of skin biopsy specimens obtained from the upper aspects of the backs of both patients revealed a markedly thickened dermis. Immunohistochemical examination of the dermal collagen bundles showed a collagen pattern similar to systemic sclerosis and normal control skin. In situ hybridization showed a markedly enhanced gene expression of transforming growth factor beta 1.
  
  
  CONCLUSIONS
  The sclerotic skin changes in GEMSS syndrome are the result of an abnormally increased production of normal collagen that might be attributable to the enhanced in situ production of transforming growth factor beta 1.
