Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BS2BP4BP7

This summary comes from the ClinGen Evidence Repository: The c.33G>C (p.Leu11=) variant results in a synonymous amino acid variant within exon 1. This variant is present at an allele frequency of 0.00012 (18/153328) in gnomAD, with a maximum frequency of 0.00026 (16/60398) in the European (Non-Finnish) subpopulation (http://gnomad.broadinstitute.org). The variant has been observed in more than 10 individuals without DGC, SRC tumours or LBC and whose families do not suggest HDGC (BS2). This variant occurs at a nucleotide that is not highly conserved across species and it is not predicted to alter splicing by multiple splice site predictors (BP7, BP4). Although one predictor suggests alteration of an exonic ESE site, the impact of these events has not been well-characterized experimentally. In summary, this variant meets criteria to be classified as likely benign based on the ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): BS2, BP4, BP7.

Genes affected
CDH1 (HGNC:1748): (cadherin 1) This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function of this gene is thought to contribute to cancer progression by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. This gene is present in a gene cluster with other members of the cadherin family on chromosome 16. [provided by RefSeq, Nov 2015]
