- Abstract
Kindler syndrome (online Mendelian Inheritance in Man No. 173650) is an autosomal recessive genodermatosis characterized by acral trauma-induced blistering that improves with age and by progressive poikiloderma in later life. Other clinical features include photosensitivity, webbing of the fingers and toes, nail dystrophy, periodontal disease, and mucosal alterations. Aside from esophageal or anal stenosis, gastrointestinal tract involvement seems to be rare in Kindler syndrome. Recently, mutations in the KIND1 gene that encodes for the membrane-associated protein kindlin-1 have been identified. Kindlin-1 links the actin cytoskeleton to the extracellular matrix and is supposed to have cell-signaling functions owing to different functional domains. In particular, a domain with high homology to 4.1/ezrin/radixin/moesin (FERM) proteins is closely related to the sequences of talin that mediate integrin binding and therefore may play a role in integrin-dependent processes such as cell growth, differentiation, and apoptosis.
