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]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a domain Protein kinase (size 260) in uniprot entity BRAF_HUMAN there are 21 pathogenic changes around while only 1 benign (95%) in NM_004333.6
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the BRAF gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 139 curated pathogenic missense variants (we use a threshold of 10). The gene has 21 curated benign missense variants. Gene score misZ: 3.7208 (above the threshold of 3.09). Trascript score misZ: 4.9447 (above the threshold of 3.09). GenCC associations: The gene is linked to LEOPARD syndrome 3, anaplastic astrocytoma, Noonan syndrome with multiple lentigines, cardiofaciocutaneous syndrome 1, Noonan syndrome, cardiofaciocutaneous syndrome, Costello syndrome, Noonan syndrome 7.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
• PP5: Variant 7-140778007-C-G is Pathogenic according to our data. Variant chr7-140778007-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 44807.Status of the report is criteria_provided_single_submitter, 1 stars.
