GeneSeq® PLUS, ATP7B
Also known as: Wilson disease
Use
This test is used for carrier and diagnostic testing for Wilson disease.
Special Instructions
Variants of uncertain significance (VUS) will be reported unless VUS opt-out is indicated on the requisition. For requests involving full gene sequencing for multiple genes, order GeneSeq® PLUS [482370]. To test fetal specimens, including cord blood, order GeneSeq® PLUS, Fetal Analysis [482389]. Test orders must include an attestation that the provider has the patient's informed consent for genetic testing.
Limitations
The technologies used in this test do not detect germline mosaicism and cannot rule out the presence of large chromosomal aberrations, including rearrangements and gene fusions. Variants in regions or genes not included in this test, as well as inter/intragenic interactions between variants or repeat expansions, are not detected. The variant classification and/or interpretation may change over time as more information becomes available. False positive or negative results may occur due to factors such as rare genetic variants, sex chromosome abnormalities, pseudogene interference, blood transfusions, somatic or tissue-specific mosaicism, mislabeled samples, or erroneous representation of family relationships.
