TrackShift: Batch Assembly-Migration Service for Legacy Genomics Assets

A service that moves old genomic data maps to the newest version so they stay accurate.

A managed service that takes a genomics lab's entire library of coordinate-based assets (custom tracks, probe panels, region lists) defined on an old reference assembly and batch-migrates them to the current one, with a QC report flagging every region that did not lift cleanly.

Concept

A managed migration service for a genomics lab's coordinate-based assets. The lab uploads its full library of custom annotation tracks, candidate-gene region lists, CNV probe coordinates, amplicon/primer panel definitions, and regulatory annotations — most clinical labs have a decade of these built on GRCh37/hg19. The service batch-transposes every asset onto the destination assembly (GRCh38/hg38 today, or any pair where a liftOver alignment exists — the stated requirement of UCSC's new QuickLift mechanism), and returns migrated files plus a per-asset QC report: regions that lifted cleanly, regions that split or collapsed, and regions with no valid chain that need manual review. A subscription re-runs the migration whenever new assemblies or chain sets are released, so assets never silently strand on an old reference. The transposition mechanism itself is demonstrated by QuickLift inside the UCSC Genome Browser; this product is the batch, scheduled, audit-trailed version of it for a whole asset library rather than a single interactively viewed track.

Why now

The 2026 UCSC Genome Browser update introduces QuickLift, which performs dynamic annotation transposition between assemblies and shows the core mechanism is production-ready — it requires only a liftOver alignment between source and destination assemblies. The same update still maintains first-class displays on both GRCh37/hg19 and GRCh38/hg38 (e.g., the ClinVar track with colored diamonds marking protein-truncating splice-acceptor, splice-donor, frameshift, and nonsense variants runs on both references), evidence that the community is mid-migration with assets stranded on each side. GenArk's expansion to over 28,000 genome assemblies means cross-assembly portability is becoming routine beyond human. What does not yet exist is the batch, QC'd, audited version of QuickLift for an entire lab's asset library — a thin, well-defined layer on a demonstrated mechanism, with obvious first users in clinical labs running exome reanalysis programs.

AI assessment

Backed by 1 paper92

A highly focused, low-risk utility service that solves a concrete pain point for clinical labs by productizing a demonstrated UCSC mechanism into an audited batch workflow.

Evidence strength
5/5
The idea directly leverages the 'QuickLift' mechanism explicitly mentioned in the UCSC 2026 update text as a production-ready tool for annotation transposition.
Market pull
4/5
Clinical labs have strict regulatory requirements for audit trails and QC when migrating patient-facing assets, creating a strong incentive to pay for a managed service over a DIY script.
Novelty & moat
4/5
While liftOver is a known concept, the shift from an interactive browser tool to a batch-processed, audited migration service for entire asset libraries is a distinct and valuable productization.
Feasibility
5/5
The core engine (QuickLift/liftOver) already exists; the MVP simply requires building the batch wrapper, file handling, and QC reporting logic.
Wedge clarity
5/5
The wedge is extremely sharp: migrating legacy GRCh37 assets to GRCh38 for clinical labs performing case reanalysis.
Simplicity / focus
5/5
The product is a single-purpose utility with a clear input (old assets) and output (migrated assets + QC report), avoiding platform bloat.

Who benefits

  • Ambry Geneticscompany

    A high-volume hereditary cancer and exome testing lab whose internal candidate-gene and region annotations were largely built on GRCh37; its exome reanalysis service needs those assets remapped to GRCh38 to stay current.

  • GeneDxcompany

    Runs one of the largest exome reanalysis programs in the US; legacy hg19-era variant and region databases must follow patients onto newer assemblies for reanalysis to work.

  • Fabric Genomicscompany

    Sells variant interpretation software to labs on mixed assemblies; a batch, QC'd migration feed keeps its annotation inputs assembly-consistent without each lab hand-lifting tracks one at a time.

  • Baylor Geneticscompany

    A clinical whole-exome/whole-genome lab with a decade of hg19-based internal assets and an active reanalysis offering that requires current-assembly coordinates.
