This sequence change replaces leucine with phenylalanine at codon 245 of the BRAF protein (p.Leu245Phe). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This missense change and a different variant (c.735A>T) giving rise to the same protein effect observed here (p.Leu245Phe) have been observed in individuals affected with BRAF-related conditions (PMID: 19206169, 22190897, 30290804), including one individual in whom the variant was de novo (PMID: 19416762). ClinVar contains an entry for this variant (Variation ID: 40347). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: Tolerated; PolyPhen-2: Probably Damaging; Align-GVGD: Class C0). For these reasons, this variant has been classified as Pathogenic.
