Genes affected
CDH1 (HGNC:1748): (cadherin 1) This gene encodes a classical cadherin of the cadherin superfamily. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion protein is comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function of this gene is thought to contribute to cancer progression by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. This gene is present in a gene cluster with other members of the cadherin family on chromosome 16. [provided by RefSeq, Nov 2015]

Hereditary diffuse gastric adenocarcinoma Benign:4
Jan 13, 2018
Illumina Laboratory Services, Illumina
Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Review Status:criteria provided, single submitter

This alteration is classified as 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. -

The CDH1 p.Asn751Asn variant was identified in 57 of 2080 proband chromosomes (frequency: 0.0274038461538462) from individuals or families with gastric cancer (Becker 1994, Berx 1997, Chen 2013, Chu 2014, Fang 2013, Zhang 2006). The variant was also identified in dbSNP (rs: rs33964119) with benign allele, ClinVar (4x as benign), Cosmic (as neutral), and the Zhejiang Colon Cancer Database (4x). The variant was not identified in MutDB, or Insight Colon Cancer Gene Variant Database. The variant was identified in control databases in 11569 of 277194 chromosomes at a frequency of 0.041736 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: Latino in 3462 (181 homozygous) of 34416 chromosomes (freq: 0.101), East Asian in 1459 (64 homozygous) of 18858 chromosomes (freq: 0.077), African in 1243 (39 homozygous) of 24026 chromosomes (freq: 0.052), South Asian in 1355 (48 homozygous) of 30782 chromosomes (freq: 0.044), Other in 232 (5 homozygous) of 6468 chromosomes (freq: 0.036), European (Non-Finnish) in 3253 (38 homozygous) of 126698 chromosomes (freq: 0.026), European (Finnish) in 448 of 25794 chromosomes (freq: 0.017). In addition, several studies classify the variant as a benign polymorphism (Berx 1997, Chen 2013, Chu 2014, Milne 2007). The p.Asn751Asn 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, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
