Diagnosis
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
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
Sanger sequencing will identify the missense and nonsense mutations, small deletions, small duplications and small insertions located in the analysed fragments. These variants are detected with 99,9% accuracy.
