Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Not Applicable

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes.
Recommended fields not provided:

Entire test performed in-house
Analytical Validity: Help
This method gives 10% concordance as compared with Southern Blotting. It is at least as sensitive as Soutern Blotting in detecting mosaic aberrant methylation.
