[Atypical Werner syndrome: Atypical progeroid syndrome: A case report].

Progeria is a premature ageing syndrome. Werner Syndrome (WS) is a type of progeria in the adult which includes bilateral juvenile cataracts and cutaneous sclerodermiform changes; it is caused by a mutation if the WRN gene which codes a helicase, a DNA repair enzyme. A case is presented of a patient, a 12 year old girl, with characteristics of WS but with no identifiable mutation in the WRN gene, therefore it was classified as atypical Werner Syndrome (AWS). 2009 Asociación Española de Pediatría.
