This quarter’s publications are showing us where genomics is headed: from incomplete views of the genome toward comprehensive, genome-wide analysis. Across population genomics, clinical whole-genome sequencing, and medical genetics, researchers are increasingly showing that long-read sequencing is becoming foundational for the next generation of genomic discovery and precision medicine.
In this second quarterly edition of Powered by PacBio, we highlight three publications from April, May, and June that show this transition. They include a landmark Chinese population pangenome paper published in Nature, a clinical study showing how HiFi whole-genome sequencing can consolidate multiple genetic tests into a single assay for reproductive medicine, and a perspective introducing the concept of Near-Perfect Genome Sequencing (NPGS) as a roadmap for the future of medical genetics.
Keep reading for a closer look at these featured publications from April through June 2026.

The 1000 Chinese Pangenome empowers medical and population genetics
In this Nature paper, researchers from China describe “1,116 diploid genome assemblies (55 de novo and 1,061 pangenome-informed) as part of the 1KCP [1000 Chinese Pangenome] project,” creating one of the largest population-specific pangenome resources to date.
Key highlights:
- Researchers built a pangenome containing “405.3 million base pairs of sequences absent from the current references GRCh38 and CHM13,” including “26.2 million base pairs of functional genic and predicted regulatory elements,” while cataloging “a full spectrum of genetic variation.”
- This resource enabled “detailed characterization of multiscale genic variations relevant to medical genetics,” including gene-altering SVs, tandem repeat expansions, gene cluster variation, and HLA haplotypes.
- The authors conclude: “As the costs of long-read sequencing continue to fall, we anticipate that this strategy will be increasingly adopted in large cohorts to advance precision medicine and benefit human health.”
Conclusion:
This study shows the power of HiFi sequencing for population-scale genomics. Even with relatively low-coverage Sequel II data, researchers generated a Nature publication and a landmark resource for medical genetics. With today’s Revio system and SPRQ-Nx chemistry, building comprehensive population pangenomes is becoming even more scalable, cost-effective, and practical for large national genomics initiatives.
Whole genome sequencing
In this multi-center study, researchers from 14 institutions led by KK Women’s and Children’s Hospital (Singapore) demonstrate that “a single long-read genome sequencing test can consolidate multiple genetic investigations and uncover clinically relevant causes in couples with unexplained subfertility and recurrent pregnancy loss.”
Key highlights:
- The authors note that “existing workflows require sequential testing and may miss complex genomic variants,” leaving “many couples … undiagnosed after multiple conventional genetic tests.”
- Using HiFi whole-genome sequencing in 84 individuals, the study found “1 in 10 couples harboring a clinically significant variant” that “would directly benefit from genetic testing.”
- HiFi sequencing also improved diagnostic confidence. For couples carrying “one pathogenic variant in recessively inherited genes,” long reads enabled researchers to “rule out any other rare coding and/or noncoding variants in the second allele, providing greater certainty.”
- Even when no causative variant was identified, the authors note that “comprehensively ruling out known genetic causes is also valuable information.”
- Beyond the primary indication, “26 individuals were identified to be carriers of a recessive genetic disease, and 1 individual has a secondary finding,” highlighting the broader value of genome-wide testing.
- Long-read sequencing also resolved complex inheritance. In one individual, “two disease-causing variants in the same gene” were shown through phasing to reside on the same allele, reducing the need for additional testing.
Conclusion:
This first publication from the HiFi Solves Subfertility Consortium in APAC adds to growing evidence that a single HiFi genome can replace multiple sequential genetic tests. By consolidating assays while improving confidence, HiFi WGS offers a streamlined approach for investigating unexplained subfertility and recurrent pregnancy loss, bringing comprehensive reproductive genomics closer to routine clinical assessments.
Medical genetics
Near-perfect genome sequencing in medical genetics
In this perspective, researchers from Radboud University Medical Center introduce Near-Perfect Genome Sequencing (NPGS), proposing that “long-read genome sequencing constitutes the foundational layer of the NPGS framework.”
Key highlights:
- The authors describe how “short-read sequencing technologies … carry well-documented blind spots,” including highly homologous regions, tandem repeats, segmental duplications, large and complex SVs, invisible base modifications, and a lack of variant phasing. As a result, they argue that “the term ‘whole-genome sequencing’ is therefore a misnomer in clinical practice.”
- To overcome these limitations, they propose that “long-read genome sequencing should be considered as one pillar of a broader technological convergence encompassing diploid genome assembly, pangenome references and AI-driven variant interpretation,” collectively termed Near-Perfect Genome Sequencing (NPGS).
- The paper highlights NPGS applications across postnatal constitutional diagnostics, where it “holds the greatest potential to consolidate the existing diagnostic toolkit under a one-test paradigm,” as well as oncology and population screening, where it addresses limitations of current short-read approaches.
- The authors also present a three-stage roadmap outlining the path from current practice to routine NPGS implementation.
- Conclusion: “NPGS carries the potential to subsume the existing diagnostic toolkit of medical genetics within a single unified framework, fundamentally reshaping the genetic diagnostics landscape over the coming decades.”
Conclusion:
This paper offers a compelling vision for the future of medical genetics—one built on long-read sequencing as its foundation. By combining HiFi sequencing with diploid assemblies, pangenomes, and AI-driven interpretation, the NPGS framework moves beyond incremental improvements toward a truly comprehensive view of the genome. As these technologies continue to mature together, HiFi is positioned to serve as the foundation for the next generation of genomic medicine.
