Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 6P and 1B. PM1PP3_StrongBS2_Supporting
The NM_004360.5(CDH1):c.1325T>C(p.Leu442Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,614,116 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L442F) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:4
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Nov 16, 2022 | This missense variant replaces leucine with serine at codon 442 of the CDH1 protein. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with CDH1-related disorders in the literature. This variant has been identified in 3/251424 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 28, 2024 | The p.L442S variant (also known as c.1325T>C), located in coding exon 10 of the CDH1 gene, results from a T to C substitution at nucleotide position 1325. The leucine at codon 442 is replaced by serine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. - |

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jan 19, 2023 | In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in an individual with a personal or family history of breast, ovarian, and/or other cancers (Tsaousis et al., 2019); This variant is associated with the following publications: (PMID: 31159747, 15235021, 22850631) - |

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 02, 2024 | This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 442 of the CDH1 protein (p.Leu442Ser). This variant is present in population databases (rs752074266, gnomAD 0.009%). This missense change has been observed in individual(s) with cancer (PMID: 31159747, 36436516). ClinVar contains an entry for this variant (Variation ID: 231246). 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. 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. - |
