Associated disorders

Inactivation of MSH2 through deletions at the 3’ end of the EPCAM gene are known to cause autosomal dominant Lynch syndrome (also called hereditary nonpolyposis colorectal cancer, or HNPCC) (MedGen UID: 40399; PMID: 23938213, 23264089, 19455606). EPCAM is also associated with autosomal recessive congenital tufting enteropathy (CTE) (MedGen UID: 413031; PMID: 18572020, 21315192).

EPCAM (epithelial cell adhesion molecule) encodes a carcinoma-associated antigen which functions as a cell adhesion molecule and is involved in cell signaling and migration, as well as embryonic stem cell proliferation and differentiation. This protein also has oncogenic potential due to its capacity to upregulate c-myc, e-fabp, and cyclins A&E.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
