Human genomics — how PacBio HiFi sequencing compares
Human genomics overview
The length and accuracy of HiFi reads allow you to access genomic dark regions such as areas of high homology, GC-rich and repetitive regions, and to resolve complex gene families like HLA and pharmacogenes like CYP2D6. PacBio HiFi reads are typically around 15 kb in length with an accuracy of 99.9% and can sequence through GC-rich regions and even repeats in segmental duplications and centromeres — all while delivering simultaneous 5-methylcytosine (5mC) calls for a commanding view of the genome

36,000 REASONS TO USE HIFI SEQUENCING
In 2019, scientists at the Mayo Clinic identified 36,794 dark regions in 6,054 gene bodies from pathways important to human health, development, and reproduction based on standard whole-genome short-read sequencing data.1 There are potentially thousands of important regions that can be missed without HiFi sequencing.
HIFI SEQUENCING REVEALS THE COMPLETE HUMAN REFERENCE GENOME
The complete, gapless human genome marks a new era of genomics where no region of the genome is beyond your reach. In 2021, PacBio’s HiFi technology was used by the Telomere-to- Telomere (T2T) Consortium to fill in those gaps.
ACHIEVE FEWER ERRORS DURING VARIANT DETECTION
PacBio’s HiFi technology was found to have the fewest total errors when compared to other technologies by the PrecisionFDA’s Truth Challenge V2: Calling variants from short and long reads in difficult-to-map regions.5
IDENTIFY INDELS WITH CONFIDENCE
A 2019 University of Washington study found that insertion-deletion mutations (indels) are routinely missed by short-read next generation sequencing (NGS) and long reads deliver 2.48 times as many structural variants as short reads alone, even “at their maximum capacity.” It is estimated that “at least 48% of deletions and 83% of insertions are routinely missed by the application of multiple short-read-calling algorithms.”2
SEE MORE STRUCTURAL VARIANTS
The 1000 Genomes Project sequenced 32 diverse reference genomes with PacBio technology, resulting in the de novo assembly of high-quality haplotype-resolved human genomes without parent-child trio data, or 64 assembled haplotypes from 32 genomes. Of the 107,590 structural variants identified, 68% were not discovered with short-read sequencing.4
OVERCOME PGX CHALLENGES
Interrogating CYP2D6 using short-read sequencing is challenging because of the degree of variation at the CYP2D6 locus and homology with its pseudogenes. Long-read sequencing can overcome these challenges.6

PAVE A PATH TO DIAGNOSTIC DISCOVERY
With 99.9% accuracy and long read lengths up to 25 kb, HiFi sequencing allows scientists to find causative pathogenic variants and identify novel disease-associated genes through:
Best-in-class variant calling for all variant types
HiFi sequencing includes solutions for single nucleotide variants (SNV), indels, copy number variants (CNVs), structural variants (SVs) and repeat expansions.
Complete, accurate, and phased assemblies of the human genome
Sequence regions previously inaccessible to other technologies — for accurate typing of genes including HLA and CYP2D6.
Achieve the coverage needed to access the complete size spectrum of cancer mutations so that you can:
- Reveal patterns of structural variants
- Characterize genotypic differences between cohorts that respond differently to treatment by phasing distant SNPs or identifying structural variants
- Look beyond SNVs and robustly detect all structural variants to reveal novel insights not possible with short-read sequencing
IDENTIFY GENETIC DRIVERS OF DISEASE
To identify the genetic drivers of diseases, scientists must have access to the complete genomic landscape, including regions previously deemed impossible to sequence, and the tools to examine the full range of genomic variation.
The PacBio systems using Single Molecule, Real-Time (SMRT) sequencing provide exceptionally long reads, uniform coverage, and high consensus accuracy. This technology enables scientists to gain a more comprehensive understanding of the genetic basis of disease.
UNDERSTAND HOW TO HARNESS THE BENEFITS OF MEDICATION
Pharmacogenomics (PGx) impacts patient care by utilizing genomic information to assess an individual’s response to certain medications. PGx can be used to predict adverse drug reactions or decreased efficacy, leading to improved health outcomes and decreased costs. An estimated 99% of people have actionable variants in PGx genes1,2, and studies have shown that up to 55% of adults2 are prescribed drugs for which there are PGx guidelines available. HiFi sequencing provides high resolution insight into PGx loci, which include complex variants such as pseudogenes, tandem repeats, and CNVs.
