Variant summary
Our verdict is Pathogenic. The variant received 19 ACMG points: 19P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Very_Strong
The NM_001374258.1(BRAF):c.1523T>C(p.Phe508Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F508L) has been classified as Uncertain significance.

In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Missense variants in this gene are often considered pathogenic (HGMD); This variant is associated with the following publications: (PMID: 26150740, 23093928, 17551924, 24803665, 31263281, 16439621, 18042262, 24957944, 15488754, 15520807, 17603483) -

BRAF-related disorder Pathogenic:1
The BRAF c.1403T>C variant is predicted to result in the amino acid substitution p.Phe468Ser. This variant has been reported in at least six individuals with cardio-facio-cutaneous syndrome (Rodriguez-Viciana et al. 2006. PubMed ID: 16439621; Gripp et al. 2007. PubMed ID: 17551924; Nava et al. 2007. PubMed ID: 17704260; Schulz et al. 2007. PubMed ID: 18042262) and one individual with Noonan syndrome (Xu et al. 2017. PubMed ID: 29084544). In at least three individuals this variant occurred de novo (Gripp et al. 2007. PubMed ID: 17551924; Schulz et al. 2007. PubMed ID: 18042262). Additionally, different amino acid substitutions affecting the same (p.Phe468Cys) and adjacent (p.Ser467Ala, p.Gly469Arg, p.Gly469Glu) amino acids have been reported as pathogenic (Human Gene Mutation Database). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-140481405-A-G). This variant is interpreted as pathogenic. -

RASopathy Pathogenic:1
ClinVar contains an entry for this variant (Variation ID: 40366). This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 468 of the BRAF protein (p.Phe468Ser). This variant is present in population databases (rs397507473, gnomAD 0.0009%). This missense change has been observed in individual(s) with cardio-facio-cutaneous syndrome or other RASopathy disorders (PMID: 16439621, 17551924, 18042262, 29084544). In at least one individual the variant was observed to be de novo. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BRAF protein function. For these reasons, this variant has been classified as Pathogenic. -
