Genes affected
EPCAM (HGNC:11529): (epithelial cell adhesion molecule) This gene encodes a carcinoma-associated antigen and is a member of a family that includes at least two type I membrane proteins. This antigen is expressed on most normal epithelial cells and gastrointestinal carcinomas and functions as a homotypic calcium-independent cell adhesion molecule. The antigen is being used as a target for immunotherapy treatment of human carcinomas. Mutations in this gene result in congenital tufting enteropathy. [provided by RefSeq, Dec 2008]

Submissions by phenotype

Lynch syndrome Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 06, 2015This sequence change deletes 21 nucleotides from exon 1 of the EPCAM mRNA (c.38_58delTTGCCGCGGCGACGGCGACTT). This leads to the deletion of 7 amino acid residues in the EPCAM protein (p.Ala14_Phe20del) but otherwise preserves the integrity of the reading frame. This variant has not been published in the literature and is not present in population databases. This deletion is in a region that encodes the signal peptide for EPCAM protein (PMID: 23618806) and signal peptides are known to be important for membrane localization during protein synthesis. However, there is no functional evidence that deletion of this region impacts EPCAM protein synthesis and/or localization. In summary, this is a novel variant with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. -
