Variant summary
Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_StrongBP6_Very_StrongBP7BS2_Supporting
The NM_004360.5(CDH1):c.1224G>A(p.Ala408=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000694 in 1,614,156 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. A408A) has been classified as Likely benign.

Benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 13, 2018 | Variant summary: CDH1 c.1224G>A alters a non-conserved nucleotide resulting in a synonymous change. 5/5 computational tools predict no significant impact on normal splicing. A functional study confirmed the lack of impact on splicing (Chen_2013). The variant allele was found at a frequency of 7.6e-05 in 277224 control chromosomes. The observed variant frequency is approximately 2.68 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH1 causing Hereditary Diffuse Gastric Cancer phenotype (2.8e-05), strongly suggesting that the variant is benign. c.1224G>A has been reported in the literature in individuals affected with gastric cancer and breast cancer (Chen_2013, Stuebs_2018). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Diffuse Gastric Cancer. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. - |

Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 21, 2014 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
