So while we're updating the data model changes we're going to simplify this:

• From the list view we want to pull out the Patient.identifier that has use: Identifier.UseEnum.Official and store this for use later. This is currently the MRN, but we will update it later to use the family number
• when you click on a specific patient, query the fhir server for all patients which have that identifier. e.g. : /Patient?identifier=969977
• if there is only one, then show this modal
  Text for modal something like:

this patient has a known pathogenic variant,  please offer cascade testing to family. Currently this is the only family member with a test result
