Topic 0: Approval of Minutes from Last Meeting


Aug 18



Topic 1: Scheduling WGM Sessions

Proposed time slots


From chat.fhir.org: Sep 2020 WGM Topics 

  • Update on joint sessions pending
  • Session order TBD



Topic 2: Missing items in the CG DR (skipped; rescheduled for date when Patrick is able to lead the discussion)

Currently Missing Coded Items which are contained in PDF Reports:


Past Discussion


  • Patrick introduced topic - will have full discussion next week
  • Bret - don't see this from Intermountain genetic reports
  • Arthur - only in somatic?
  • Patrick - for breast cancer
  • Anand - found in panel, not any one gene
  • Bob D - variant profile may not be good for reporting loss of heterozygosity




Topic 3: Uncallable Regions (continued discussion)

Indeterminates via region-studied FHIR-25296


  • Group had determined to do subtraction before reporting
  • Needs guidance       
  • Uncallable regions were still “studied”
  • Add guidance and examples to not use Variant to convey a non-callable gene
  • Proposal B: allow Observation.value to convey callability
  • “No Call different from Absent” on variant answer list




  • Add in extensible binding to 
  • (Present LA9633-4 | No Call LA18198-4 | Unknown LA4489-6)




  • Future extensible Options for value
  • ( Callable | uncallable ) | high-quality | intermediate quality
  • Proposal C: separate profile for listing uncallable regions
  • Proposal A: add uncallable sub-region component
  • Hard to convey uncallable whole genes



FHIR-25296

Persuasive with Modification

Uncallable subregions in a region studied

Bob Dolin

To allow full use of the current profile's components, add in a required [1..1] value for region-studied (currently 0..0) with an extensible binding to a local answer list with the 3 LOINC answer codes: (Present LA9633-4 | No Call LA18198-4 | Unknown LA4489-6). Add in textual guidance for this value, along the lines of:  'When reporting regions of study, the value field is used to filter regions by callability. A value of "Present" shall accompany components describing a region fully called by the lab, so that omission of variant results within that region implies wildtype calls in the sample, compared to a specified reference. A value of "No Call" shall accompany components describing a region explicitly deemed uncallable by the lab. A value of "Unknown" shall accompany components describing a region where callability varies, for example the full list of genes studied in a panel. Omission of variants within a "No Call" or "Unknown" region shall not be used to imply wildtype calls in the sample.'


Discussion:
Jamie: Goal is to clarify the profile.

Bob M.: There is a difference between region targeted vs found

BoB F.: Targeted regions should also be included. 3 concepts:  intended to be targeted, what was assayed, what was the call

Uncallable would be option 3(what was the call), A gene panel is 1(intended to be targeted),  

Possibly breaking examples: target gene, find pseudogene. Target gene, which isn’t actually present.

Targeting gene which is often not present. This could be a Variant: absent only filling out the gene id.

Target Gene: ServiceRequest? Order specific genes/mutations to look at. Standard screening panel - may be planDefinition/etc. 

Bob M.: We need guidance on ServiceRequest, “if you want to find the target gene, it has to be included in the ServiceRequest.”

    PlanDefinition used by eMerge

What was assayed? Region-studied
Make sure guidance text reflects the meaning.

(what was found? Findings: variant/haplotype/genotype)

Component:gene-mutations is a duplication of parts of the variant profile?

Revisit code of region-studied profile: 53041-0 DNA region of interest panel → which isn’t representing the callability of a region.

Discussion

  • http://build.fhir.org/ig/HL7/genomics-reporting/StructureDefinition-region-studied.html
  • change Present to Callable to answer list
  • get proper code with clear definition
  • use code/answer-list for a new component (rather than observation.value)
  • create temporary answer list
  • https://chat.fhir.org/#narrow/stream/179197-genomics/topic/STU2.20Theme.3A.20Uncallable.20subregions.20in.20a.20region.20studied
    • Graphical example of SNPs in regions studied vs not studied
    • Concerns of definition(s) of callability - 
      • Test limitations as separate observation/model
  • Bob F: when reporting variant results, there’s 
      • a list of variants in context of a reference
      • Statements about the variants (eg heterozygous)
    • The subject of this (region studied) is not a variant - subject of the statement is closely related to the assaying (and the interrogated sequence)
      • Target of the $find-subject-variants operation is not necessarily a database of variants, could be a server storing raw sequencing data (or FHIRized Observations)
  • Liz: suggest we look at eMerge’s usage (or lack thereof) of the region-studied structure
    • relatedArtifact for gene-coverage
    • https://emerge-fhir-spec.readthedocs.io/en/latest/design.html#example-reports
      • Issue 8: request from eMerge to support multiple regions on one instance (possible now, bound to 1 max reference sequence: could be 23 callable region studied observations -- and potentially 23 uncallable region studied observations)
    • Bret: Reports do not NEED to include regions studied, could have (or be able to have) them as needed -- just send details for how/where to find them - architecture around implementing the IG
  • Bob D: reports often come back with read depth and % coverage across the entire studied region - not able to do when limited to 1 reference seq per instance


Future Topics

Orders for genetic testing

  • How to define ServiceRequest.code
  • Multiple tests per report?

LOINC changes for Level of Evidence / Clinical Significance



Need to consider the following two new motions:

    • Motion A: Use 53037-8 for both germline and somatic variant clinical significance reporting, and add information to the Term description about the different guidelines for somatic and germline variants;  Keep the Answer list the same, but update the type from Preferred to Example


  • 1st/2nd -
  • Discussion -
  • Abstain/Nay/Yea -  / /
  • Result -


(Notes from Jamie:)

  • Want to separate clinical significance from level of evidence.
  • Motion B: Consider creating new codes for diagnostic, therapeutic, and prognostic significance (see Quest screenshot, LabCorp report) and/or type of evidence (see Baylor report)
    • 1st/2nd -
    • Discussion -
    • Abstain/Nay/Yea -  / /
    • Result - 
  • Need to create an example to understand the meaning of this change/concepts.
  • Need a caretaker for this topic.

spitballing ideas. would a barnstorming campaign be useful? e.g. asking/virtually taking education to vendors, labs, clinical genetic leadership directly...
