Submissions by phenotype
Hereditary diffuse gastric adenocarcinoma Benign:2
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:2
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. -

Breast and/or ovarian cancer Benign:1

Malignant tumor of breast Benign:1
The CDH1 p.Arg784= variant was not identified in the literature. The variant was identified in dbSNP (ID: rs768796172) as "With Likely benign allele" and in ClinVar (classified as likely benign by Invitae and Ambry Genetics). The variant was identified in control databases in 1 of 246250 chromosomes at a frequency of 0.000004 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European population in 1 of 111708 chromosomes (freq: 0.000009), while the variant was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Arg784= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
