RCV001180416 | SCV001345344 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-04 | criteria provided, single submitter | clinical testing | This missense variant replaces methionine with threonine at codon 381 of the CHEK2 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with CHEK2-related disorders in the literature. This variant has not been identified 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. |
Invitae | RCV002558952 | SCV002999905 | uncertain significance | Familial cancer of breast | 2023-08-25 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 381 of the CHEK2 protein (p.Met381Thr). 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. 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. ClinVar contains an entry for this variant (Variation ID: 921159). This variant has not been reported in the literature in individuals affected with CHEK2-related conditions. This variant is not present in population databases (gnomAD no frequency). |
Ambry Genetics | RCV001180416 | SCV004006494 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-31 | criteria provided, single submitter | clinical testing | The p.M381T variant (also known as c.1142T>C), located in coding exon 10 of the CHEK2 gene, results from a T to C substitution at nucleotide position 1142. The methionine at codon 381 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
