Next-generation sequencing (NGS) is rapidly becoming the method of choice for mutation analysis in both research and diagnostics. The benefit of targeted NGS compared to whole-genome and whole-exome sequencing is that smaller amounts of input material can be used as well as qualitatively suboptimal tissue samples, like formalin-fixed, paraffin-embedded archival tissue.Here, we describe the protocol for targeted next-generation sequencing using the Ion Torrent PGM platform in combination with Ion Ampliseq NGS gene panels for formalin-fixed, paraffin-embedded tissues. Both the manual and the automated workflow are described as well as the bioinformatics for data analysis.
