Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_004360.5(CDH1):c.1466C>A(p.Pro489His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P489L) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | May 24, 2021 | Variant summary: CDH1 c.1466C>A (p.Pro489His) results in a non-conservative amino acid change located in the Cadherin-like domain (IPR002126) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant was absent in 251486 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1466C>A in individuals affected with Hereditary Diffuse Gastric Cancer and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. - |
Hereditary diffuse gastric adenocarcinoma Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 28, 2018 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CDH1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with histidine at codon 489 of the CDH1 protein (p.Pro489His). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and histidine. - |
