Kindler surprise: mutations in a novel actin-associated protein cause Kindler syndrome

      Summary

      Kindler syndrome is an autosomal recessive genodermatosis characterized by acral blistering in neonates and diffuse, progressive poikiloderma in later life. Other clinical features include photosensitivity, premature skin ageing and severe periodontal disease. Two groups have recently shown that the molecular basis of Kindler syndrome is loss of a novel epidermal protein, kindlin-1, encoded by the gene KIND1. Two additional kindlin proteins, kindlin-2 and kindlin-3, have also been described. Kindlin-1 is considered to be a component in the linkage of the actin cytoskeleton to the extracellular matrix and as such is proposed to have both structural and cell-signalling functions. Kindler syndrome is therefore the first skin fragility syndrome due to disruption of the actin–extracellular matrix system.

      Biography

      W.H. Irwin McLean graduated from The Queen's University of Belfast, Northern Ireland with a BSc(Honours) in Microbiology in 1985 and a PhD in Human Genetics in 1988. He worked as a Research Assistant in Medical Genetics in Belfast from 1985 to 1991 and as a Postdoctoral Fellow in Department of Anatomy and Physiology, University of Dundee, Scotland from 1992 to 1996. He moved to Thomas Jefferson University, Philadelphia, USA in 1996 where he was Associate Professor in Dermatology and Cutaneous Biology until 1998, when he returned to Ninewells Medical School at the University of Dundee as a Wellcome Trust Senior Research Fellow and from 2002, as Professor of Human Genetics. He was awarded a DSc degree from The Queen's University of Belfast in 1999 for his work on inherited skin diseases. He sits on the Editorial boards of the Journal of Investigative Dermatology and Journal of Dermatological Science. His main research interest is understanding the genetics and molecular pathology of hereditary diseases that cause fragility of the epidermis, its appendages and other epithelial tissues. Recently, the emphasis of his work has begun to move away from gene mapping and gene function towards therapy development for inherited skin disorders.
