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]

Benign, criteria provided, single submitterclinical testingGeneDxSep 11, 2017This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Likely benign, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesAug 23, 2019This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
not provided Benign:1
Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 24, 2017Variant summary: The BRAF c.483G>C (p.Leu161=) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. 5/5 splice prediction tools predict no significant impact on normal splicing. This variant was found in 8/121376 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.000673 (7/10404). This frequency is about 269 times the estimated maximal expected allele frequency of a pathogenic BRAF variant (0.0000025), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, one clinical diagnostic laboratory classified this variant as likely benign. The variant of interest has neither been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories nor was it evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -
Cardiovascular phenotype Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2022This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
