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: The c.976A>G (p.Ile326Val) in BRAF gene is a missense change that involves a non-conserved nucleotide and 5/5 in silico tools predict benign outcome. The variant is located outside of any known functional domain and behaved like wildtype in phosphorylation assay (Razzaque_2007). The variant is present in the large control population datasets of ExAC and gnomAD at a frequency 0.00009 and 0.000075, respectively (11/ 121408 and 21/ 277182 chrs tested, respectively), predominantly in individuals of East Asian descent ( allele frequency: 0.00104 and 0.0007, respectively). These frequencies exceed the maximal estimated expected frequency of a pathogenic allele (0.0000025) in this gene. The variant was identified in one patient with Noonan syndrome who also carried a de novo mutation in BRAF gene, p. E501K, a known pathogenic variant associated with CFC. Taking together, the variant was classified as Benign. -
