Description

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in individuals with Lynch-related and other cancers (Bonadona et al., 2011; Tung et al., 2016; Akcay et al., 2020); This variant is associated with the following publications: (PMID: 21642682, 12624141, 26976419, 31391288, 33471991, 21120944, 18822302, 33558524, 32658311, 31422574)

Description

The frequency of this variant in the general population, 0.000004 (1/251078 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in individuals with Lynch syndrome (PMID: 21642682 (2011)), breast cancer (PMID: 26976419 (2016), 33558524 (2021), 32658311 (2021)), and colorectal cancer (PMID: 32658311 (2021)). The variant has also been reported in unaffected individuals (PMID: 33471991 (2021), 31422574 (2019)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, we are unable to determine the clinical significance of this variant.
