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]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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. -

Significance:Likely benign

Review Status:no assertion criteria provided

Collection Method:clinical testing

The CDH1 p.Thr38= variant was not identified in the literature, nor was it identified in COSMIC, Zhejiang Colon Cancer Databases. The variant was identified in dbSNP (ID: rs786201492) as With Likely benign allele, Clinvar database (classified as likely benign by Ambry Genetics, Invitae), Clinvitae databases. The variant was identified in control databases in 1 of 30924 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include East Asian in 1 of 1620 chromosomes (freq: 0.0006), while the variant was not observed in the African, Other, Latino, European, Ashkenazi Jewish, Finnish, and South Asian populations. The p.Thr38= 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, 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. -
