Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BP7

This summary comes from the ClinGen Evidence Repository: The c.*7T>C variant in the 3' UTR of BRAF is classified as likely benign because it occurs in a noncoding region, computational splice analyses do not predict an impact on splicing, and Alamut indicates that this nucleotide is not highly conserved (BP4, BP7). It has been identified in 0.0008791% (1/113754) of non-Finnish European chromosomes in gnomAD v2. RASopathy-specific ACMG/AMP Criteria applied (PMID:29493581): BP4, BP7.

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]
