Molecular characterization of biologically diverse envelope variants of human immunodeficiency virus type 1 derived from an individual.

ABSTRACT

The envelope genes of six viruses derived from a single sampling from an individual chronically infected with human immunodeficiency virus type 1 (RJS-4) have been analyzed. Here we present the nucleotide and predicted amino acid sequences of these variants and show a correlation between biological properties and disturbance of the envelope reading frame.
