Design and Application of Multiplex PCR Seq for the Detection of Somatic Mutations Associated with Myeloid Malignancies.

Targeted sequencing, in which only a selected set of genomic loci are sequenced, enables a much higher coverage of each target than what is obtained using whole genome or exome sequencing. Multiplex PCR offers a simple and affordable technique for specific capture of target regions and can be easily adapted to generate next-generation sequencing (NGS)-ready amplicons. Here we describe a multiplex PCR (MxPCR) approach for capturing 13 leukemia-associated mutation hotspots followed by MiSeq sequencing that enables robust detection of mutations with a variant allele fraction (VAF) as low as 0.8% (0.008) in blood DNA.
