GeneDx RCV000414586 SCV000491448 uncertain significance not specified 2016-02-08 criteria provided, single submitter clinical testing The Q344L variant has not been published as a pathogenic variant or been reported as a benign variant to our knowledge. This variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The Q344L variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved in mammals. Nevertheless, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Furthermore, no missense variants in nearby residues have been reported in the Human Gene Mutation Database in association with BRAF-related disorders (Stenson et al., 2014).Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or benign.
