GeneDx RCV000160448 SCV000211010 uncertain significance not provided 2023-09-25 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); Minigene assays demonstrate an incomplete splice defect resulting in multiple aberrant transcripts as well as some full-length transcript (Sanoguera-Miralles et al., 2023); In silico analysis supports that this variant does not alter splicing; This variant is associated with the following publications: (PMID: 37725924)
Invitae RCV001350944 SCV001545372 uncertain significance Familial cancer of breast 2022-06-27 criteria provided, single submitter clinical testing 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 182448). 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). This sequence change falls in intron 2 of the CHEK2 gene. It does not directly change the encoded amino acid sequence of the CHEK2 protein. It affects a nucleotide within the consensus splice site.
