Test strategy:
Help
Testing is performed by exome capture of the coding regions of relevant genes followed by next generation sequencing to detect small sequence variants. Starred tests (*) include additional testing for deletions and duplications by an alternate methodology (aCGH) when sequencing does not identify genetic variation consistent with a molecular diagnosis. …

Analytical Validity:
Help
Sensitivity, specificity, and positive predictive value (PPV) of this test to detect single base-pair substitutions in coding regions were at least 96.6%,100.0%, and 99.3%, respectively, and were determined by comparison of the genotypes at known single-nucleotide polymorphisms determined by this assay from a HapMap DNA sample to the genotypes at …
