RCV000690254 | SCV000817935 | uncertain significance | Hereditary diffuse gastric adenocarcinoma | 2023-12-31 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 750 of the CDH1 protein (p.Asp750Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with hereditary diffuse gastric cancer (PMID: 28688938, 36436516, 36509094). ClinVar contains an entry for this variant (Variation ID: 569585). 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. |

Ambry Genetics | RCV001183070 | SCV002725011 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-07 | criteria provided, single submitter | clinical testing | The p.D750N variant (also known as c.2248G>A), located in coding exon 14 of the CDH1 gene, results from a G to A substitution at nucleotide position 2248. The aspartic acid at codon 750 is replaced by asparagine, an amino acid with highly similar properties. This alteration has been reported in 2 different individuals with hereditary diffuse gastric cancer (HDGC) (Hansford S et al. JAMA Oncol, 2015 Apr;1:23-32; Mi EZ et al. Gastrointest. Endosc., 2018 02;87:408-418). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
