Abstract
An embodiment of a method for detecting low frequency occurrence of one or more HIV sequence variants associated with integrase is described that comprises the steps of: (a) generating a cDNA species from a plurality of RNA molecules in an HIV sample population; (b) amplifying a plurality of first amplicons from the cDNA species, wherein each first amplicon is amplified with a pair of nucleic acid primers capable of amplifying products from clades A, B, C, D, AE and G sub-types; (c) clonally amplifying the amplified copies of the first amplicons to produce a plurality of second amplicons; (d) determining a nucleic acid sequence composition of the second amplicons; (e) detecting one or more sequence variants that occur at a frequency of 5% or less in the nucleic acid sequence composition of the second amplicons; and (f) correlating the detected sequence variants with variation associated with HIV integrase.
