title: Status of the ICP34.5 gene in herpes simplex virus type 1 strain 17.
abstract: In the published DNA sequence of herpes simplex virus type 1 (HSV-1) strain 17 the coding region for the neurovirulence factor ICP34.5 is disrupted by a 2 bp insertion relative to the corresponding sequence in HSV-1 strain F; this difference would render 60% of the ICP34.5 coding sequence out of frame in strain 17. Re-investigation of the strain 17 sequence showed that the plasmid clone used as the major sequencing substrate for the region was atypical in that other clones did not possess the 2 bp insertion. It was concluded that the coding sequence for ICP34.5 is intact in HSV-1 strain 17 and that the HSV-1 DNA sequence should be revised at this locus.
