Genes affected
BRAF (HGNC:1097): (B-Raf proto-oncogene, serine/threonine kinase) This gene encodes a protein belonging to the RAF family of serine/threonine protein kinases. This protein plays a role in regulating the MAP kinase/ERK signaling pathway, which affects cell division, differentiation, and secretion. Mutations in this gene, most commonly the V600E mutation, are the most frequently identified cancer-causing mutations in melanoma, and have been identified in various other cancers as well, including non-Hodgkin lymphoma, colorectal cancer, thyroid carcinoma, non-small cell lung carcinoma, hairy cell leukemia and adenocarcinoma of lung. Mutations in this gene are also associated with cardiofaciocutaneous, Noonan, and Costello syndromes, which exhibit overlapping phenotypes. A pseudogene of this gene has been identified on the X chromosome. [provided by RefSeq, Aug 2017]

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. -

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. -
