Analytical Validity:
Help
The sensitivity of DNA sequencing is over 99% for the detection of nucleotide base changes, small deletions and insertions in the regions analyzed.
Assay limitations:
Help
Mutations in regulatory regions or other untranslated regions are not detected by this test. Large deletions involving entire single exons or multiple exons, large insertions and genetic recombinational events may not be identified using these methods. Rare primer site variants may lead to erroneous results.
