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

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PM1

In a hotspot region, there are 21 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 11 uncertain in NM_001374258.1

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: 4.9008 (above the threshold of 3.09). GenCC associations: The gene is linked to cardiofaciocutaneous syndrome, Noonan syndrome with multiple lentigines, Noonan syndrome, cardiofaciocutaneous syndrome 1, Noonan syndrome 7, LEOPARD syndrome 3, anaplastic astrocytoma, Costello syndrome.

PP5

Variant 7-140781623-C-A is Pathogenic according to our data. Variant chr7-140781623-C-A is described in ClinVar as Pathogenic. ClinVar VariationId is 13962.Status of the report is no_assertion_criteria_provided, 0 stars.
