10.6 Resource Sequence - Content

Clinical Genomics Work GroupMaturity Level: 1 Trial Use Compartments: Not linked to any defined compartments

Raw data describing a biological sequence.

At present, the Sequence resource is multi-purpose. It can be used to represent a “definitional” sequence, as might be found in a knowledge-base source in a patient- and specimen-independent manner. It can also be used to represent information about a specific finding when testing a specimen, including qualifying information about confidence, uncertainty, etc. The Clinical Genomics workgroup is considering modifying the resource to be definition-only, removing the ability to convey patient, specimen and observation-specific information. Such data elements would instead be conveyed using the Observation resource, as this is more typically used in the lab setting to report patient-specific results. The Sequence resource would be retained for sharing of genetic knowledge, such as reference sequences, quality metrics, and links to external repository sequences. Feedback about this proposed change is welcome.

For insight into what the new approach to representing patient-specific genetic information, refer to the Implementation Guide (IG) for clinical genomics reporting, which can be found here .

10.6.1 Scope and Usage

The Sequence resource is designed to describe an atomic sequence which contains the alignment sequencing test result and multiple variations. Atomic sequences can be connected by link element and they will lead to sequence graph. By this method, a sequence can be reported. Complete genetic sequence information, of which specific genetic variations are a part, is reported by reference to the GA4GH repository. Thus, the FHIR Sequence resource avoids large genomic payloads in a manner analogous to how the FHIR ImagingStudy resource references large images maintained in other systems. For use cases, details on how this resource interact with other Clinical Genomics resources or profiles, please refer to implementation guidance document here .

10.6.1.1 Genetic Standards and Resources include:

This resource is designed to describe sequence variations with clinical significance with information such as:

  • Name of the variation represented
  • Type of the variation
  • Gene region occupied by the variation
  • Tissue source used to determine genotype of the variation
  • Quality of the result

It is strongly encouraged to provide all available information in this resource for any reported variants, because receiving systems (e.g. discovery research, outcomes analysis, and public health reporting) may use this information to normalize variants over time or across sources. However, these data should not be used to dynamically correct/change variant representations for clinical use outside of the laboratory, due to insufficient information.

Implementers should be aware that semantic equivalency of results of genetic variants cannot be guaranteed unless there is an agreed upon standard between sending and receiving systems.

10.6.2 Boundaries and Relationships

Focus of the resource is to provide sequencing alignment data immediately relevant to what the interpretation on clinical decision-making originates from. Hence data such as precise read of DNA sequences and sequence alignment are not included; such data are nonetheless accessible through references to GA4GH (Global Alliance for Genomics and Health) API. The Sequence resource will be referenced by Observation to provide variant information. As clinical assessments/diagnosis of a patient are typically captured in the Condition resource or the ClinicalImpression resource, the Sequence resource can be referenced by the Condition resource to provide specific genetic data to support an assertions. This is analogous to how Condition references other resources, such as AllergyIntolerance, Procedure, and Questionnaire resources.

This resource is referenced by observation

10.6.3.2 Constraints

  • seq-3: Only 0 and 1 are valid for coordinateSystem (expression : coordinateSystem = 1 or coordinateSystem = 0)
  • seq-5: On Sequence.referenceSeq: GenomeBuild and chromosome must be both contained if either one of them is contained (expression on Sequence.referenceSeq: (chromosome.empty() and genomeBuild.empty()) or (chromosome.exists() and genomeBuild.exists()))
  • seq-6: On Sequence.referenceSeq: Have and only have one of the following elements in referenceSeq : 1. genomeBuild ; 2 referenceSeqId; 3. referenceSeqPointer; 4. referenceSeqString; (expression on Sequence.referenceSeq: (genomeBuild.count()+referenceSeqId.count()+ referenceSeqPointer.count()+ referenceSeqString.count()) = 1)

10.6.4 Notes:

10.6.4.1 Sequence Coordinate System

When saving the variant information, the nucleic acid will be numbered with order. Some files are using 0-based coordiantes (e.g. BCD file format) while some files are using 1-based coordinates (e.g. VCF file format) . The element coordinateSystem in Sequence Resource contains this information.

Sequence.coordinateSystem constraints within two possible values: 0 for 0-based system, which will mark the sequence from number 0, while 1 for 1-based system, which will begin marking the first position with number 1. The significant difference between two system is the end position. In 0-based system, the end position is exclusive , which means the last position will not be contained in the sequence window while in 1-based system, the end position is inclusive , which means the last position is included in the sequence window. Note both systems has an inclusive start position.

For example, ACGTGCAT will be numbered from 1 to 8 in 1-based system and will be numbered from 0 to 8 in 0-based system to mark flanks (i.e. place between two Nucleotide). So the interval [3,5] in 1-based system is GTG while interval [2,5) in 0-based system is same segment GTG.

10.6.4.2 Choice of Strand

There are lots of definition concerning with the Directionality of DNA or RNA. Here strand element in Sequence resource is defined to have constraints with value +1 and -1 , to indicate what is the direction for nucleotide series. In order to avoid confusion, we use +1 to express the "plus" strand (5' to 3') and -1 to express the "minus" strand (3' to 5'). Here is a very simple mapping that indicates which number the expression will be represented.

+1 -1
Watson Crick
Sense Antisense
positive negative

Here is a small-scale example: if 5' GCGATATCGCAAA 3' is the data, then GC..AAA is plus strand while AAA..CG is the minus strand.

10.6.4.3 String usage for Reference Sequence and Observed Sequence

We hope that string of observedSeq can be constrained more than just any normal string but with notation tables. Here we present what the nucleotide acid stirng should be constrianed within the range:

A --> adenosine M --> A C (amino) U --> uridine H --> A C T V --> G C A
C --> cytidine S --> G C (strong) D --> G A T K --> G T (keto)
G --> guanine W --> A T (weak) R --> G A (purine) N --> A G C T (any)
T --> thymidine B --> G T C Y --> T C (pyrimidine) - --> gap of indeterminate length
while the amino acid string should be constrained within the range:
A alanine P proline B aspartate or asparagine Q glutamine
C cystine R arginine D aspartate S serine
E glutamate T threonine F phenylalanine U selenocysteine
G glycine V valine H histidine W tryptophan
I isoleucine Y tyrosine K lysine Z glutamate or glutamine
L leucine X any M methionine * translation stop
N asparagine - gap of indeterminate length

10.6.5 Search Parameters

Search parameters for this resource. The common parameters also apply. See Searching for more information about searching in REST, messaging, and services.

NameTypeDescriptionExpressionIn Common
chromosometokenChromosome number of the reference sequenceSequence.referenceSeq.chromosome
coordinatecompositeSearch parameter for region of the reference DNA sequence string. This will refer to part of a locus or part of a gene where search region will be represented in 1-based system. Since the coordinateSystem can either be 0-based or 1-based, this search query will include the result of both coordinateSystem that contains the equivalent segment of the gene or whole genome sequence. For example, a search for sequence can be represented as `coordinate=1$lt345$gt123`, this means it will search for the Sequence resource on chromosome 1 and with position >123 and <345, where in 1-based system resource, all strings within region 1:124-344 will be revealed, while in 0-based system resource, all strings within region 1:123-344 will be revealed. You may want to check detail about 0-based v.s. 1-based above.Sequence.variant
