Targeted Colorectal Tumor Mutation: Sequencing Panel
Test Code: 7002
Turnaround time: 3 to 4 weeks
Somatic genetic testing of colorectal cancer.
AKT1, APC, BRAF, CTNNB1, EGFR, FBXW7, KRAS, MET, NRAS, PIK3CA, PTEN, SRC, TP53
- For suspected sporadic cancer. This test is NOT indicated for inherited cancers.
Next Generation Sequencing: In-solution hybridization of the regions encompassing full exonic gene sequences is performed on the tumor DNA. Direct sequencing of the captured regions is performed using next generation sequencing (NGS). The tumor genes’ sequences are then compared to a standard reference sequence. All sequence variants are evaluated using current scientific data to identify pathogenic, likely pathogenic variants, variants of unknown significance (VOUS) and carrier status. Benign and likely benign variants are identified and classified using the latest published, scientific data are not listed in the report. Variants of unknown significance (VOUS) that are either synonymous or outside coding regions are classified as likely benign.
Next Generation Sequencing: Clinical Sensitivity: Pathogenic variants in regions other than the targeted area, including the promoter region, some mutations in the introns and other regulatory element mutations, cannot be detected by this analysis. Large deletions/duplications will not be detected by this analysis. Results of molecular analysis should be interpreted in the context of the patient’s clinical/biochemical phenotype.
Analytical Sensitivity: ~99%.
