Variant summary

Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP7BP5BA1BP4

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.1227A>G (p.Ser409=) variant in the BRAF gene is 0.313% for European (Non-Finnish) chromosomes by the Exome Aggregation Consortium (233/66620 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1). Additionally, this variant is a synonymous (silent) variant at a nucleotide that is not highly conserved and is not predicted to impact splicing (BP7). The p.Ser409= variant has been identified in a patient with an alternate molecular basis for disease (BP5; GeneDx, Partners LMM, EGL Genetics internal data; GTR ID's: 21766, 26957, 500060; SCV000057203.8; SCV000061570.5; SCV000112807.7). Computational prediction tools and conservation analysis suggest that the p.Ser409= variant does not impact the protein (BP4). In summary, this variant meets criteria to be classified as benign. ACMG/AMP criteria applied: BA1, BP7, BP5, BP4. LINK:https://erepo.genome.network/evrepo/ui/classification/CA135058/MONDO:0021060/004

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]

Apr 27, 2017
Illumina Laboratory Services, Illumina
Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
