Unlock Rare Disease Genomics
Improvements in sequencing technology are increasing the ability of scientists to provide answers and shorten the diagnostic odyssey for patients with rare diseases.
Rare Diseases Need Better Solutions
Although rare diseases are individually rare, collectively they are common, affecting 1 in 2,000 people worldwide with 80% of cases being genetic in origin and >50% of cases remaining unsolved. This is despite after patients undergoing diagnostic tests using approaches including microarrays, whole exome, or short-read whole genome sequencing.
Highly accurate long-read sequencing, known as HiFi sequencing, provides a higher resolution approach compared to previously used technologies to better understand the genetic causes of rare disease.
The Benefits of HiFi Sequencing for Rare Diseases
With accuracy >99.9% and long read lengths up to 25 kb, HiFi sequencing allows scientists to find causative pathogenic variants in individuals and identify novel disease-associated genes in patient cohorts with:
- Best-in-class variant calling for all variant types including single nucleotide variants (SNV), indels, copy number variants (CNVs), and structural variants (SVs)
- Complete, accurate, and phased assemblies of the human genome— including regions previously inaccessible to other technologies— for accurate typing of genes including HLA and CYP2D6

Spotlight: Children's Mercy Hospital Uses HiFi Sequencing in Genomic Answers for Kids Study
In this presentation, Dr. Emily G. Farrow of Children’s Mercy Kansas City discusses three patient cases in which PacBio HiFi sequencing was able to provide answers where other technologies had failed due to several challenges including phasing of variants, achieving even sequence coverage, and sequencing repetitive regions.
Children’s Mercy Kansas City is expanding its investment in PacBio Sequel IIe Systems to scale up whole genome research initiatives focused on rare disease diagnosis. Learn More
Spotlight: 12 kb Inversion Identified as Causative in Syndromic Intellectual Disability
HiFi sequencing of a trio identifies a pathogenic heterozygous 12 kb de novo inversion that disrupts BRPF1 the gene. SNVs (marked with “*”) show that the inversion occurred on the maternal allele #3. Read more about this study in the blog post.
