The RecQ family of DNA helicases have potential roles in DNA repair, replication and/or recombination pathways. In humans, a defect in the RecQ family helicases encoded by the BLM, WRN and RECQ4 genes gives rise to Bloom's (BS), Werner's (WS) and Rothmund-Thomson (RTS) syndromes, respectively. These disorders are associated with cancer predisposition and/or premature aging. In Bloom's syndrome, affected individuals are predisposed to many types of cancer at an early age. Werner's syndrome is a premature aging disorder with a complex phenotype, which includes many age-related disorders that develop from puberty, including greying and thinning of the hair, bilateral cataract formation, type 11 diabetes mellitus, osteoporosis and atherosclerosis. The phenotype of Rothmund-Thomson syndrome patients also consists of some features associated with premature aging, as well as predispositon to certain cancers. Here, we discuss the molecular basis of these RecQ helicase-deficient disorders. (C) 2002 Elsevier Science Ltd. All rights reserved.
