Functional deficiency of the FEN1 gene has been suggested to cause genomic instability and cancer predisposition. We have identified a group of FEN1 mutations in human cancer specimens. Most of these mutations abrogated two of three nuclease activities of flap endonuclease 1 (FEN1). To demonstrate the etiological significance of these somatic mutations, we inbred a mouse line harboring the E160D mutation representing mutations identified in human cancers. Selective elimination of nuclease… CONTINUE READING
