Abstract

We introduce a massively parallel novel sequencing platform that combines an open flow cell design on a circular wafer with a large surface area and mostly natural nucleotides that allow optical end-point detection without reversible terminators. This platform enables sequencing billions of reads with longer read length ([~]300bp) and fast runs times ( 85%), at a low cost of $1/Gb. We establish system performance by whole-genome sequencing of the Genome-In-A-Bottle reference samples HG001-7, demonstrating high accuracy for SNPs (99.6%) and Indels in homopolymers up to length 10 (96.4%) across the vast majority (>98%) of the defined high-confidence regions of these samples. We demonstrate scalability of the whole-genome sequencing workflow by sequencing an additional 224 selected samples from the 1000 Genomes project achieving high concordance with reference data.

Open flow cell on a circular wafer with mostly natural nucleotides and no reversible terminators: about 300 bp reads at $1/Gb, 99.6% SNP accuracy on reference human genomes.

Sequencing cost and read length govern how widely whole genomes can be sequenced. This platform reads incorporation by optical end-point detection with mostly natural nucleotides, without reversible terminators, on an open large-area circular-wafer flow cell, at a reported cost of $1/Gb and read length around 300 bp.

Key results

  1. ShownWhole-genome sequencing of the Genome-In-A-Bottle reference samples reached high small-variant accuracy, including for insertions and deletions inside homopolymer runs.

    On samples HG001-7: 99.6% accuracy for SNPs and 96.4% for insertions and deletions in homopolymers up to length 10, covering more than 98% of the samples' defined high-confidence regions. · Abstract

  2. ClaimedThe platform is reported to deliver billions of reads at read length around 300 bp and a cost of $1/Gb.

    Stated as platform capability enabled by the open circular-wafer flow cell and terminator-free chemistry; no run-level throughput table, instrument time or comparison with other platforms is given in the abstract. · Abstract

  3. ClaimedThe whole-genome workflow was run at a larger scale on population-genomics samples and reported to agree closely with existing reference calls.

    224 further samples selected from the 1000 Genomes Project were sequenced; the concordance with reference data is asserted without a percentage, variant class breakdown or discordance analysis. · Abstract

Methods, data and reproducibility

A massively parallel sequencing-by-synthesis platform built on an open flow cell on a large-surface circular wafer, using mostly natural nucleotides so that base incorporation is detected optically at end point rather than through reversible terminators; performance was established by whole-genome sequencing of reference samples and then a larger panel of population samples.

Limitations (2)
  • Accuracy is quoted only within the high-confidence regions defined for the reference samples, so behaviour in the harder remainder of the genome is not addressed. · noted in this summary
  • No head-to-head comparison with an established sequencing platform is reported, and the concordance on the 224 population samples carries no number. · noted in this summary

Who should read:Read this if you commission large-scale human whole-genome sequencing and want the accuracy and cost profile of a terminator-free chemistry.
