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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.06984127 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.

PS3

PS3 evidence extracted from ClinVar submissions: SCV004865654: RNA studies have demonstrated that this alteration results in abnormal splicing (Sivagnanam, 2008).

PP5

Variant 2-47375300-G-A is Pathogenic according to our data. Variant chr2-47375300-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 12771.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
