Abstract

Werner syndrome is an autosomal recessive disorder resulting from loss of function of the RecQ helicase, WRN protein. WS patients prematurely develop numerous clinical symptoms and diseases associated with aging early in life and are predisposed to cancer. WRN protein and many other RecQ helicases in general, seem to function during DNA replication in the processing of stalled replication forks. Genetic, cellular and biochemical evidence support roles for WRN in proper replication and repair of telomeric DNA, and indicate that telomere dysfunction contributes to the WS disease pathology.
