Invitae | RCV000231135 | SCV000287355 | uncertain significance | Lynch syndrome | 2016-01-07 | criteria provided, single submitter | clinical testing | This sequence change deletes 6 nucleotides from exon 1 of the EPCAM mRNA (c.51_56delGGCGAC). This leads to the deletion of 2 amino acid residues in the EPCAM protein (p.Ala18_Thr19del) but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a EPCAM-related disease. 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. |
