Abstract
An embodiment of a method for detecting low frequency occurrence of one or more HIV sequence variants associated with drug resistance is described that comprises the steps of: generating cDNA species from each RNA molecule in an HIV sample population; amplifying at least one first amplicon from the cDNA species, wherein each first amplicon comprises a plurality of amplified copies and is amplified with a pair of nucleic acid primers that define a locus of the first amplicon; clonally amplifying the amplified copies of the first amplicons to produce a plurality of second amplicons wherein a plurality of the second amplicons comprise an immobilized population of substantially identical copies from one of the amplified copies of first amplicons; determining a nucleic acid sequence composition of the substantially identical copies from at least 100 of the immobilized populations in parallel on a single substrate; and detecting one or more sequence variants that occur at a frequency of 5% or less in the nucleic acid sequence composition of the at least 100 immobilized populations; and correlating the detected sequence variants with variation associated with HIV tropism.
