Result Interpretation

An interpretive report will be provided.

Interpretation:

All detected variants are evaluated according to American College of Medical Genetics and Genomics

recommendations.(1) Variants are classified based on known, predicted, or possible pathogenicity and

reported with interpretive comments detailing their potential or known significance.
