When the primary draft of the human genome was accomplished within the early 2000s, the opportunity of utilizing genomic knowledge in routine healthcare appeared near turning into actuality. Now, greater than 20 years later, genomics has made inroads into healthcare — however it nonetheless has not made it into every day affected person care. Scientists and clinicians at Human Longevity (HLI) are working to alter that.
In a latest webinar, Wayne Delport, vp of expertise & bioinformatics at HLI, described the whole-genome sequencing product and scientific report that the corporate developed for physicians and sufferers in its Well being Nucleus Clinic. He additionally talked about how the DNAnexus Platform is offering much-needed bioinformatics infrastructure to assist the clinic ingest, analyze, and interpret the information.

“Human Longevity was based on the premise that the genome was going to revolutionize the observe of medication and make a major influence on the mixing of genomics and drugs,” Delport mentioned. “We’ve seen loads of that within the oncology area, however we’re not fully satisfied we’ve seen that within the main care area.”
To create a complete genome product that may profit folks coming in for a wholesome screening, HLI launched the Well being Nucleus, a data-driven personalised well being platform that appears throughout all the information from a wholesome particular person. “It’s meant to alter the way in which healthcare is practiced,” Delport mentioned.
As a substitute of the standard method to healthcare, which depends totally on knowledge from household historical past and bodily examination, the Well being Nucleus staff collects knowledge from whole-genome sequencing, imaging, and completely different sorts of biomarkers. Underneath this new mannequin, physicians have entry to AI-powered analytics to make sense of the sufferers’ knowledge.
A New Sort of Scientific Report
When HLI started creating its complete genome sequencing product, they rapidly realized that there was no present report construction appropriate for describing the ends in a way that was partaking for each purchasers and physicians. So that they determined to create one.
The report wanted to be easy sufficient for purchasers to know whereas concurrently offering helpful data to clinicians together with prognostic danger evaluation knowledge and pharmacogenomics data; nevertheless, it couldn’t be used for diagnostic functions.
The present model of the HLI report has 4 sections; hereditary illness danger, pharmacogenomics findings, well being predisposition, and vitamin and wellness traits. The Human Longevity Scientific Laboratory (HLCL), a CAP/CLIA licensed lab at HLI, points these experiences.
The hereditary illness danger portion of the report gives knowledge on pathogenic and sure pathogenic variants and illness danger. The pharmacogenomics part of the report captures data on star alleles and their features in addition to related drug response knowledge. The following part presents knowledge on polygenic danger. The ultimate part of the report gives data on vitamin and wellness traits to assist sufferers and clinicians focus on well being habits, train wants, illness susceptibility, reactions to meals, and extra.
Highly effective Information Analytics
These experiences are solely doable because of the infrastructure for analyzing, deciphering, and storing the massive portions of information generated by complete genome sequencing assays. HLI at the moment companions with a CAP/CLIA validated reference laboratory for its complete genome sequencing wants, whereas it handles the evaluation in home. HLCL is validated to evaluate single nucleotide variants and small insertions and deletions.
To deal with its bioinformatics wants, HLI beforehand relied on an in-house workflow that ran on Amazon Net Companies. It included separate pipelines for secondary and tertiary evaluation and interpretation. These had been all internally developed, so the HLI staff was liable for the maintenance. The system additionally had loads of elements, together with a number of PostgreSQL databases and software programming interfaces.
“We had been liable for sustaining our workflows [and] sustaining our infrastructure,” Delport mentioned. “We additionally needed to develop our personal privateness and safety program.” Additionally they needed to optimize storage prices.
HLI not too long ago started transitioning its evaluation to the cloud-based DNAnexus Platform, together with secondary evaluation instruments developed by Sentieon. When the transition is full, they may have a a lot less complicated expertise stack that makes use of fewer elements than the one they constructed in-house.
“The beauty of this for us is that we’ve got one SQL database with one API that we don’t need to develop. That’s developed and maintained by DNAnexus,” Delport mentioned.
This additionally signifies that HLI scientists can concentrate on the essential activity of extracting useful well being data from the sufferers’ genomes and reporting their findings.
“We don’t have to fret about any infrastructure administration,” Deplort mentioned. “The one factor folks on our staff have to fret about is constructing and deploying bioinformatics instruments which can be utilized in our reporting workflow.”
DNAnexus’ Platform meets the entire compliance requirements required for safe storage and switch of complete genome knowledge, in addition to these required for bioinformatics pipelines and knowledge monitoring in response to the CAP Molecular Pathology guidelines. “DNAnexus greater than meets these necessities for us,” Delport mentioned. ”We had been comfy with the safety and traceability.”
Utilizing DNAnexus can also be less expensive per pattern than HLI’s unique infrastructure. Even at 10 p.c of HLI’s present quantity, doing the evaluation on DNAnexus is 62 p.c less expensive than utilizing its inside infrastructure. And the fee financial savings improve as the quantity of samples analyzed goes up.
HLI has begun piloting its complete genome reporting in another clinics past the Well being Nucleus. It is usually creating a brand new product referred to as the Genome Search Engine which focuses extra on variant discovery and has a wider scope than the entire genome product. “We wish to be an interface between a scientific care supplier within the genomics area and genomic interpretation,” Delport mentioned.
