SMART/FHIR Genomic Resources An overview... For latest see http://smartgenomics.wikispaces.com/Clinical+Genomics+Presentation
Change Log • Made a few changes to Sequence resource • Added data support for alignment data (e.g. SAM or BAM file) • VCFMeta, VCFVariant, GVFMeta, GVFVariant, AlignmentMeta, AlignmentRead are exchanged using REST path /binary, recognized as a Binary resource • SequencingLab replaced with an extension to Procedure resource • GeneticObservationreplaced with an extension to Observation resource
List of Genomic Resources • Genetic Observation • Implemented as an extension to Observation resource • Summary of genetic test • Documentation of phenotype-genotype association • Clinical decision support
Extension to Observation resource • Added fields below to establish genotype-phenotype association • traitAssesed : CodeableConcept // 0..1 Target phenotype in the observation; reason why the observation is performed • variantIdentifier: 1..1HGVS nomenclature of the variant • variant: Resource(Sequence) // 1..1 reference to genotype
List of Genomic Resources • Raw data encapsulation (e.g. VCF Variant) • Encapsulates a row of raw genetic data (VCF, GVF, SAM, BAM) • With reference to original file • Change note: We now support encapsulation of alignment files SAM/BAM
List of Genomic Resources • Abstract representation - Sequence • An abstraction of VCFVariant/GVFVariant • Enables developer to view genotypes without being constrained by file formats • References raw data (e.g. reference to VCFVariant)
List of Genomic Resources • Sequencing Lab • “Folders” containing files of genetic data • Facilitates collaboration in research (files can be shared via the API between various labs) • Implemented as an extension to Observation resource
Extension to Observation Observation • Added fields below to document sequencing labs • species : CodeableConcept // 1..1 species of the sample used in asequencing lab • sampleType: code // 1..1 type of the sample used in asequencing lab • sampleSource: CodeableConcept // 0..1 specific sample used • assembly : code // 0..1 assembly used in for alignment for analysis • file: Attachment // 0..* files generated from a sequencing lab
Use Case – Clinical Decision Support • Developer A has access to database for genotype-phenotype association • Query Sequence resource with region of interest • Map the result against database and find out potential risk factor of patient • Profile discovery of such risk factors with GeneticObservation
Use Case – File Analysis • Developer B found some VCF files attached in /procedure/123 as result generated from sequencing lab • User can query for regions that he/she is interested in using the API • VCFVariant – variant (genotypic) information • VCFMeta – legends that help user understand some of the user-defined data within the variant info
