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]

This missense variant replaces threonine with methionine at codon 115 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast cancer in the literature (PMID: 29522266) but also in control individuals (PMID: 30287823). This variant has been identified in 7/282510 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The frequency of this variant in the general population, 0.000047 (6/128864 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been identified in women affected with breast cancer (PMID: 29522266 (2018), 34130653 (2021)) or at-risk of breast/ovarian cancer (PMID: 31159747 (2019), 34359559 (2021)). It was also identified only in the control groups for studies of biliary tract cancer (PMID: 36243179 (2022)), breast cancer (PMID: 30287823 (2018)), pancreatic cancer (PMID: 32980694 (2020)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded conflicting predictions that this variant is benign or damaging. Based on the available information, we are unable to determine the clinical significance of this variant. -
