Ambry Genetics | RCV000565709 | SCV000669263 | pathogenic | Hereditary cancer-predisposing syndrome | 2018-08-16 | criteria provided, single submitter | clinical testing | The c.597delT pathogenic mutation, located in coding exon 4 of the CHEK2 gene, results from a deletion of one nucleotide at nucleotide position 597, causing a translational frameshift with a predicted alternate stop codon (p.F199Lfs*6). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |
Invitae | RCV000635856 | SCV000757281 | pathogenic | Familial cancer of breast | 2023-10-18 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Phe199Leufs*6) in the CHEK2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CHEK2 are known to be pathogenic (PMID: 21876083, 24713400). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with CHEK2-related conditions. ClinVar contains an entry for this variant (Variation ID: 483374). For these reasons, this variant has been classified as Pathogenic. |

RCV000565709 | SCV001340296 | pathogenic | Hereditary cancer-predisposing syndrome | 2020-03-16 | criteria provided, single submitter | clinical testing | This variant deletes 1 nucleotide in exon 5 of the CHEK2 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of CHEK2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. |
