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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.2501443).
BS2
High AC in GnomAdExome4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 82 of the CDH1 protein (p.Val82Met). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer (PMID: 36436516). ClinVar contains an entry for this variant (Variation ID: 419434). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.V82M variant (also known as c.244G>A), located in coding exon 3 of the CDH1 gene, results from a G to A substitution at nucleotide position 244. The valine at codon 82 is replaced by methionine, an amino acid with highly similar properties. This variant has been identified in at least one patient with a personal and family history of breast and/or ovarian cancer (Maxwell KN et al. Am J Hum Genet, 2016 May;98:801-817). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces valine with methionine at codon 82 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with early-onset breast cancer in the literature (PMID: 25503501). This variant has been identified in 3/251404 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. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is denoted CDH1 c.244G>A at the cDNA level, p.Val82Met (V82M) at the protein level, and results in the change of a Valine to a Methionine (GTG>ATG). This variant has been observed in at least one individual with early-onset breast cancer (Maxwell 2015). CDH1 Val82Met was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Valine and Methionine share similar properties, this is considered a conservative amino acid substitution. CDH1 Val82Met occurs at a position that is not conserved and is located in the precursor sequence (Brooks-Wilson 2004). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether CDH1 Val82Met is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
