UCSF Common Hereditary Cancer Panel

Performing Lab: 
UCSF Clinical Cancer Genomics Lab
CPT Code: 
81432, 81435

Specimen Type: Peripheral blood, Saliva (collected in Oragene kit), Buccal cells, DNA (minimum 2 micrograms)

Methodology:  Next generation sequencing

Turnaround time:  14 – 28 days

TEST INDICATIONS: 

Designed for patients with a family history suggestive of a common hereditary cancer. The common hereditary cancer panel tests for variants in 47 genes associated with hereditary breast, ovarian, uterine, colorectal, melanoma, and prostate cancers.

HOW THE TEST WORKS: 

DNA is extracted for library preparation. Genomic regions of interest are targeted using a custom capture reagents (Sophia Genetics) for target enrichment and sequenced using an Illumina sequencing system with 150bp paired-end reads. The resulting DNA sequences are mapped to and analyzed in comparison with the published human genome (UCSC hg19 reference sequence). Variants, including SNVs and CNVs, are called and annotated using a custom bioinformatics pipeline developed in collaboration with Sophia Genetics.   

All pathogenic, likely pathogenic, and variants of uncertain significance meeting the reportable criteria are reported. SNVs and indel variants are specified using the numbering and nomenclature recommended by the Human Genome Variation Society (HGVS, http://www.hgvs.org/). Benign variants are not reported. Variant classification and confirmation are consistent with ACMG standards and guidelines (Richards, PMID:25741868; Rehm, PMID:23887774).  

GENES ANALYZED: This list represents a complete list of genes analyzed for this individual. This assay covers the coding and splice regions (+/- 10bp) of the included genes, including the relevant gene transcript(s). Results are negative unless otherwise indicated in the report. Benign and Likely Benign variants are not included in this report but are available upon request. An asterisk (*) indicates that this gene has a limitation. Please see the Limitations section for details.

LIMITATIONS OF THE TEST: 

Absence of a plausible explanation for the reported clinical phenotype by this sequencing test does not exclude a genetic basis for disease. Some types of genetic variation, including germline mosaicism, or the presence of large chromosomal aberrations such as structural rearrangements, gene fusions, or variants in regions or genes not included in this test, may not be detectable with the technologies used by this test. Regions outside of the coding regions, so called non-coding sequences, are not captured and analyzed, but may harbor disease-causing variants.  In the event of a negative result, the presence of an inherited cancer syndrome due to a different genetic cause cannot be ruled out. Variant classification and/or interpretation may change over time, when additional information becomes available.  It is also possible that incomplete scientific and/or medical knowledge of genes and variants, pseudogene interference, technical issues including sample mislabeling, blood transfusions, bone marrow transplantation, or erroneous misrepresentation of family relationships, may result in a false negative or false positive test result.  For heterozygous variants in the same gene, the assay typically cannot determine whether they are on the same (in cis) or different (in trans) chromosomes.  In order to determine variant phase, parental testing may be required.   

This test was developed and its performance characteristics determined by the UCSF Clinical Cancer Genomics Laboratory. It has not been cleared or approved by the U.S. Food and Drug administration. This test is for clinical purposes and should not be considered as investigational or for research purposes.
