Abstract
PURPOSE: Genomic medicine holds great promise for improving health care, but integrating searchable and actionable genetic data into electronic health records (EHRs) remains a challenge. Here we describe Neptune, a system for managing the interaction between a clinical laboratory and an EHR system during the clinical reporting process.Entities:

Modes for running Neptune.
Neptune can be run in multiple different modes, specified by command line parameters.
| Command | Input(s) | Description |
|---|---|---|
| annotate | vcf, project configuration | Annotates vcf with data from the VIP. Marks if a variant has been previously seen or needs review |
| renderPreReport | VIP annotated vcf, configuration information for external data, report template, project configuration | Loads data from external sources, creates a structured output files |
| renderFinalReport | Pre-report file, project configuration | Populates the pre-report with the final set of data. Separate in case it needs to run in a PHI environment |
| reanalyze | VIP annotated vcf | Takes an existing VIP annotated vcf, shows differences to current VIP |
Figure 1:Overview of Neptune functionality.
A. Neptune manages the variant review process and brings together disparate data from multiple external systems in order to create a final report file, in either json, html or FHIR format. Central to this process is the ‘VIP’ database of genetic variation. For each sample, novel genomic variants are added to this database and curated as needed according to project-specific rules. B. The contents of the VIP database includes curated variants. VIP database variants are predominantly VUS or Likely Benign.
Figure 2:Variant Review Burden Over Time.
The plot shows the number of variants per sample requiring review in 68 eMERGE III consensus reportable genes, starting with an empty database. As additional samples are reviewed from a data freeze of 7258, the number of variants per sample that are selected quickly decreases. In eMERGE III, the number of variants that require review plateaus at around 1 variant per sample.
Figure 3:eMERGE III reanalysis activities.
Neptune supported two parallel reanalysis activities during the eMERGE III project. First was a project with the goal of providing updated reports when variant classifications change (3A) over time. To accomplish this, we used Neptune’s reanalysis module to compare a ClinVar snapshot to local variant categorizations. We identified upgrades and downgrades by detecting either unreported variants with a new Pathogenic / Likely pathogenic classification in ClinVar or a reported variant with a new VUS, Benign or Likely benign classification. There were 26 upgrades for review, resulting in 3 updated reports (all initially VUS) and 86 downgrades for review, resulting in 2 updated reports. Next, we collected a set of VUS variants that were lacking one ACMG/AMP subcategory to reach an overall classification of likely pathogenic (3B). We then contacted clinical sites requesting more detailed patient phenotype information, in order to be able to apply the PP4 ACMG/AMP subcategory (Patient phenotype or family history highly specific for gene). In four cases we were able to issue updated reports, all due to the new clinical information. In a separate study, we reanalyzed 83 variants based on additional clinical information requested from clinical sites for variants that were VUS but which could be reclassified as Likely Pathogenic with the application of one ACMG subcategory. This resulted in four updated reports and highlights the importance of detailed clinical information during review by clinical geneticists.
