SequenceConsensusSequenceBlock FHIR Profile Proposal

From HL7Wiki
Jump to navigation Jump to search


Describes consensus sequence block used in HLA typing report.

This profile was created to attempt to satisfy the requirements for a specific use case: HLA genotyping by NGS methods. It is based on the principles of the Minimum Information for ReportIng Next generation sequence Genotyping (MIRING) as described in Hum Immunol. 2015 Dec;76(12):954-62. doi: 10.1016/j.humimm.2015.09.011. Epub 2015 Sep 25. A technical implementation of MIRING was developed in the Histomimmungenetics Markup Language (HML) and published in Hum Immunol. 2015 Dec;76(12):963-74. doi: 10.1016/j.humimm.2015.08.001. Epub 2015 Aug 28. The schema for HML may be found in

We are using MIRING and HML to inform how FHIR profile(s) may be developed. In this case, a Consensus Sequence is composed of one or more Consensus Sequence Blocks. Metadata about each block is important, but not yet captured in the Sequence Resource, or other profiles. These include: phase set, expected copy number, block continuity, and strand. This profile extends the Sequence Resource to add these elements.

Profile balloting plans


Profile Details

Profiled Resource(s)

Constraints to be Applied

The following constraints are applied to the Sequence resource as necessary:

  • Constrain the cardinality of the data elements within the resource.
  • Constrain the mustSupport attribute of the data elements within the resource.
  • Define searchParameters as necessary for the resource.
  • Constrain vocabularies for the resources as applicable.

Extensions to be Applied

The following extensions are applied to the Sequence resource as appropriate:

  • Clinical genomics specific extensions.

Example Scenarios

  • Query Examples for each resource.
  • Query Result Examples for each resource.

Scope of coverage

  • Subject: patient
  • Disciplines: Patient Care, Clinical Research, Public Health
  • Delivery Environment: Inpatient, Ambulatory, Community, Emergency, etc.


Clinical genomics.
