What is myChoice® CDx?
Hereditary Cancer and Tumor Testing - Why Use Both?
Using a hereditary cancer test as a part of the ovarian cancer workup can provide critical information about hereditary risk to make the best treatment decisions for your patient. You can receive both hereditary and tumor treatment answers in one order by using Myriad. Learn more below.
To learn how to order both hereditary cancer and tumor testing in one order, email myChoiceCDx@myriad.com or call 877-283-6709

myChoice® CDx Intended Use
Myriad myChoice® CDx is a next generation sequencing-based in vitro diagnostic test that assesses the qualitative detection and classification of single nucleotide variants, insertions and deletions, and large rearrangement variants in protein coding regions and intron/exon boundaries of the BRCA1 and BRCA2 genes and the determination of Genomic Instability Score (GIS) which is an algorithmic measurement of Loss of Heterozygosity (LOH), Telomeric Allelic Imbalance (TAI), and Large-scale State Transitions (LST) using DNA isolated from formalin-fixed paraffin embedded (FFPE) tumor tissue specimens.
The results of the test are used as an aid in identifying ovarian cancer patients with positive homologous recombination deficiency (HRD) status, who are eligible, because of a positive test result for deleterious or suspected deleterious mutations in BRCA1 or BRCA2 genes, or may become eligible, because of a positive test result for deleterious or suspected deleterious mutations in BRCA1 or BRCA2 genes or a positive Genomic Instability Score, for treatment with the targeted therapy listed in Table 1 in accordance with the approved therapeutic product labeling.
Table 1: Companion diagnostic indications
| Tumor Type | Biomarker | Therapy |
|---|---|---|
| Ovarian Cancer | Myriad HRD (defined as deleterious or suspected deleterious mutations in BRCA1 and BRCA2 genes and/or positive Genomic Instability Score) | Lynparza® (olaparib) Zejula® (niraparib) |
Detection of deleterious or suspected deleterious BRCA1 and BRCA2 mutations and/or positive Genomic Instability Score in ovarian cancer patients is also associated with enhanced progression-free survival (PFS) from Zejula® (niraparib) maintenance therapy. This assay is for professional use only and is to be performed only at Myriad Genetic Laboratories, Inc., a single laboratory site located at 320 Wakara Way, Salt Lake City, UT 84108.
