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]

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: BRAF c.1150A>G (p.Arg384Gly) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00018 in 251312 control chromosomes, exclusively reported within the East Asian subpopulation at a frequency of 0.0025, in the gnomAD database. The observed variant frequency within East Asian control individuals is approximately 1000-fold of the estimated maximal allele frequency expected for a pathogenic variant in BRAF causing Noonan Syndrome and Related Conditions phenotype (2.5e-06), strongly suggesting that the variant is a benign polymorphism. c.1150A>G has been reported in the literature in a fetus with abnormal ultrasound findings (suspected of Noonan Syndrome) and in individuals with various cancer phenotypes (Croonen_2013, Zhang_2015, Griffith_2018), however, without strong evidence for causality. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two submitters, including an expert panel (ClinGen RASopathy Variant Curation Expert Panel), have provided clinical-significance assessments for this variant in ClinVar after 2014, and classified the variant as likely benign / benign (expert panel). Based on the evidence outlined above, the variant was classified as benign. -
