Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 25, 2023 | 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with BRAF-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change results in a frameshift in the BRAF gene (p.Gly759Aspfs*13). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 8 amino acid(s) of the BRAF protein and extend the protein by 4 additional amino acid residues. - |
