Ambry Genetics | RCV002407409 | SCV002716717 | pathogenic | Hereditary cancer-predisposing syndrome | 2021-05-27 | criteria provided, single submitter | clinical testing | The p.E58* pathogenic mutation (also known as c.172G>T), located in coding exon 3 of the CDH1 gene, results from a G to T substitution at nucleotide position 172. This changes the amino acid from a glutamic acid to a stop codon within coding exon 3. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |

RCV002407409 | SCV004360436 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-08-08 | criteria provided, single submitter | clinical testing | This variant changes 1 nucleotide in exon 3 of the CDH1 gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in an individual with no history of diffuse gastric cancer but was found affected with signet ring cell carcinoma (SRCC) upon endoscopy (PMID: 30935944), and in several members of one family reporting no history of diffuse gastric cancer (PMID: 27064202). Clinical laboratories have classified numerous other truncations in exon 3 of CDH1 as pathogenic in ClinVar. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of CDH1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. |

RCV003336713 | SCV004366595 | pathogenic | Hereditary diffuse gastric adenocarcinoma | 2023-12-17 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Glu58*) in the CDH1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CDH1 are known to be pathogenic (PMID: 15235021, 20373070). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CDH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1778959). For these reasons, this variant has been classified as Pathogenic. |
