Resolution is to merge the $find-subject-variants operation ( http://build.fhir.org/ig/HL7/genomics-reporting/branches/fhir_operations/find-subject-variants.html ) into the Master branch. (Additional change proposals to the operation are still welcome, and will be managed in the Master branch). Description of $find-subject-variants operation: Use this operation to retrieve variants with precise endpoints from a specified genomic region for a specified patient. If the range in question has been studied, the operation returns variants overlapping the region. If the patient or the specified region has not been studied, the operation returns a 404 error. IN Parameters: subject [1..1] genomicRefSeq [1..1] range (numeric within the ref seq) [1..1] OUT Parameters: regionStudied [0..1] variant [0..*] sequencePhaseRelationships [0..*] Additional resolutions include: operation name: $find-subject-variants context: [base] /$find-subject-variants include discussion of normalization and liftover, including expectations of the server Details of the operation are here: http://build.fhir.org/ig/HL7/genomics-reporting/branches/fhir_operations/find-subject-variants.html
