VistaSeq® Lynch Syndrome Panel
Also known as: Familial Cancer testing, Hereditary Cancer testing, Inherited Cancer testing
Use
This assay is intended for patients with a personal or family history consistent with Lynch syndrome.
Special Instructions
Not provided.
Limitations
Sequencing cannot detect variants in regions not covered by this analysis, including noncoding or deep intronic variants and may not reliably detect changes in repetitive elements, such as microsatellite repeats. Sequencing may not detect mosaic variants, inversions, or other genomic rearrangements such as transposable element insertions. Copy number analyses may not detect certain genomic rearrangements, such as translocations (balanced or unbalanced), inversions, or some partial exon rearrangements. The presence of pseudogenes can interfere with the ability to detect variants in certain genes.
