Labcorp Genetics (formerly Invitae), Labcorp RCV001215821 SCV001387584 likely pathogenic RASopathy 2019-08-01 criteria provided, single submitter clinical testing This sequence change replaces leucine with valine at codon 567 of the BRAF protein (p.Leu567Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed to be de novo in an individual affected with BRAF-related conditions (Invitae). This variant is not present in population databases (ExAC no frequency).
