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]

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces threonine with proline at codon 529 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in a cohort of 1040 individuals affected with advanced cancer (PMID: 28873162). This variant has been identified in 4/282886 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 CDH1 c.1585A>C variant is predicted to result in the amino acid substitution p.Thr529Pro. This variant has been reported in an individual with advanced cancer (eTable, Mandelker et al. 2017. PubMed ID: 28873162). This variant is reported in 4 of ~283,000 alleles in gnomAD (http://gnomad.broadinstitute.org/variant/16-68853202-A-C). It is interpreted as uncertain in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/186165/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 529 of the CDH1 protein (p.Thr529Pro). This variant is present in population databases (rs776890776, gnomAD 0.02%). This missense change has been observed in individual(s) with unspecified cancer type (PMID: 28873162). ClinVar contains an entry for this variant (Variation ID: 186165). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The proline amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
