Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP3_StrongPP5
The NM_004360.5(CDH1):c.760G>A(p.Asp254Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D254Y) has been classified as Pathogenic.

CDH1-related disorder Pathogenic:1
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. -

Hereditary diffuse gastric adenocarcinoma Uncertain:1
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. -
