This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -

Hereditary cancer-predisposing syndrome Benign:4
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. -

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. -
