von Hippel-Lindau Disease (VHL): VHL (OPT) (Full Gene Sequencing)
Use
Confirm a clinical diagnosis of VHL; identify presymptomatic family members
Special Instructions
Not provided.
Limitations
This methodology does not reliably detect mosaic variants, large deletions, large duplications, inversions, or other rearrangements. It also does not effectively identify deep intronic variants. This test may be affected by allele-dropout, might not allow determination of the exact number of T/A or microsatellite repeats, and it cannot conclusively determine whether two heterozygous variants are present on the same or different chromosome copies. Additionally, the test has not been cleared or approved by the Food and Drug Administration.
