Test purpose: Help
Diagnosis; Mutation Confirmation
Recommended fields not provided:
Clinical validity, Clinical utility, Target population, What is the protocol for interpreting a variation as a VUS?, Are family members with defined clinical status recruited to assess significance of VUS without charge?, Will the lab re-contact the ordering physician if variant interpretation changes?, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Comments: Help
Genomic sequencing
Prenatal diagnosis by sequencing only
Availability: Help
