Abstract

At present, the most common genetic diagnostic method for chimerism evaluation following hematopoietic stem cell transplantation is microsatellite analysis by capillary electrophoresis. The main objective was to establish, through repeated analysis over time, if a complete chimerism was present, or if the mixed chimerism was stable, increasing or decreasing over time. Considering the recent introduction of next generation sequencing (NGS) in clinical diagnostics, a detailed study evaluating an NGS protocol was conducted, coupled with a custom bioinformatics pipeline, for chimerism quantification. Based on the technology of Ion AmpliSeq, a 44‑amplicon custom chimerism panel was designed, and a custom bioinformatics pipeline dedicated to the genotyping and quantification of NGS data was coded. The custom chimerism panel allowed identification of an average of 16 informative recipient alleles. The limit of detection of the protocol was fixed at 1% due to the NGS background (<1%). The protocol followed the standard Ion AmpliSeq library preparation and Ion Torrent Personal Genome Machine guidelines. Overall, the present study added to the scientific literature, identifying novel technical details for a possible future application of NGS for chimerism quantification.
