Invitae | RCV000821162 | SCV000961909 | uncertain significance | Familial cancer of breast | 2023-03-04 | 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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 663307). This variant has not been reported in the literature in individuals affected with BARD1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 26 of the BARD1 protein (p.Met26Leu). |
Ambry Genetics | RCV002397719 | SCV002668792 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-07-03 | criteria provided, single submitter | clinical testing | The p.M26L variant (also known as c.76A>C), located in coding exon 1 of the BARD1 gene, results from an A to C substitution at nucleotide position 76. The methionine at codon 26 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. 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. |
