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]

The CDH1 c.760G>A variant is predicted to result in the amino acid substitution p.Asp254Asn. This variant has been reported in multiple individuals with nonsyndromic cleft lip and/or palate (Figure S1, Brito et al. 2015. PubMed ID: 26123647; Table 1, de novo, Cox et al. 2018. PubMed ID: 29805042; Table S3, de novo Bishop et al. 2020. PubMed ID: 32574564; Alvizi et al. 2023. PubMed ID: 37225711), and blepharocheilodontic syndrome (Table 2, Kievit et al. 2018. PubMed ID: 29348693). This variant has segregated within families with incomplete penetrance (Brito et al. 2015. PubMed ID: 26123647; Alvizi et al. 2023. PubMed ID: 37225711; Kievit et al. 2018. PubMed ID: 29348693). This variant has not been reported in a large population database, indicating this variant is rare. An in vivo experimental study in zebrafish suggests this variant affects craniofacial development and an in vitro experimental study suggests that this variant has a dominant negative effect (Figure 3 and 4, Kievit et al. 2018. PubMed ID: 29348693). An alternate nucleotide substitution affecting the same amino acid (p.Asp254Tyr) has been reported in an individual with nonsyndromic cleft lip and/or palate (Figure 1, Pan et al. 2021. PubMed ID: 34592648), and blepharocheilodontic syndrome (Figure 1, Ghoumid et al. 2017. PubMed ID: 28301459). In summary, the c.760G>A (p.Asp254Asn) variant is interpreted as pathogenic. -

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 254 of the CDH1 protein (p.Asp254Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with cleft lip/palate or blepharocheilodontic syndrome (PMID: 26123647, 29348693, 29805042, 32574564). ClinVar contains an entry for this variant (Variation ID: 834043). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on CDH1 function (PMID: 26123647, 29348693). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
