RCV003328284 | SCV001142265 | pathogenic | CDH1-related diffuse gastric and lobular breast cancer syndrome | 2023-08-29 | reviewed by expert panel | curation | The c.124_126delCCCinsT (p.Pro42Serfs*16) variant is predicted to result in a premature stop codon that leads to a truncated or absent protein (PVS1, PM5_Supporting). The variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). This variant has been reported in at least one family meeting HDGC clinical criteria (PS4_Supporting; PMID 30745422). In summary, this variant meets criteria to be classified as pathogenic based on the ACMG/AMP criteria applied as specified by the CDH1 Variant Curation Expert Panel (Variant Interpretation Guidelines Version 3.1): PVS1, PM2_Supporting, PS4_Supporting, PM5_Supporting. |
Ambry Genetics | RCV000215517 | SCV000274663 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-03-09 | criteria provided, single submitter | clinical testing | The c.124_126delCCCinsT pathogenic mutation, located in coding exon 2 of the CDH1 gene, results from the deletion of 3 nucleotides and insertion of one nucleotide causing a translational frameshift with a predicted alternate stop codon (p.P42Sfs*16). 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. |

RCV000991097 | SCV001417924 | pathogenic | Hereditary diffuse gastric adenocarcinoma | 2023-08-30 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individual(s) with clinical features of hereditary diffuse gastric cancer syndrome (PMID: 30745422, 31296550). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Pro42Serfs*16) 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). |
