Detection of low prevalence somatic mutations in solid tumors with ultra-deep targeted sequencing

Abstract: Ultra-deep targeted sequencing (UDT-Seq) can identify subclonal somatic mutations in tumor samples. Early assays' limited breadth and depth restrict their clinical utility. Here, we target 71 kb of mutational hotspots in 42 cancer genes. We present novel methods enhancing both laboratory workflow and mutation detection. We evaluate UDT-Seq true sensitivity and specificity (> 94% and > 99%, respectively) for low prevalence mutations in a mixing experiment and demonstrate its utility using six tumor samples.

“…1, data from mixture experiments A (SRR385938), B (SRR385939), C (SRR385940) and D (SRR385941) from Harismendy et al 12 were downloaded from the NCBI short read archive. Each dataset was generated by physically mixing DNA from four tissue samples from the 1000 genomes project in different proportions.…”

“…Primer start and stop positions for the UDT-Seq protocol were obtained from Supplemental Table 2 of Harismendy et al 12 . We downloaded hg19 from UCSC website and used primer positions to build a targeted reference alignment file which contained only the regions spanned by the primers.…”

“…20 α-Galactosidase A activity evaluation by tandem mass spectrometry Enzyme analysis was performed as previously described. 20 GLA gene analysis GLA gene variants were searched for in pooled DNA using massively parallel sequencing 21 or in individual genomic DNA samples using the Illumina MiSeq platform (Illumina, Inc.; San Diego, CA). Briefly, the SmartChip MyDesign TE system (WaferGen Bio-systems, Inc., Fremont, CA) was designed to enrich multiple samples for multiple resequencing targets simultaneously using a 4-polymerase chain reaction primer amplification strategy.…”

“…Ved universitetet i California, San Diego, har de etablert en analyse der 42 kreftgener sekvenseres «ultradypt», dvs. at hver base i disse genene ble sekvensert i gjennomsnitt 24 000 ganger, for Ă„ finne mutasjoner som er til stede i bare en ytterst liten andel av kreftcellene, men som kan vaere den del av svulsten som gir resistens og tilbakefall (17).…”
