Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PM1PM2PM5PP2PP3_StrongPP5

The NM_001374258.1(BRAF):​c.1910T>G​(p.Leu637Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,368 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L637P) has been classified as Uncertain significance.

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: Pathogenic. The variant received 12 ACMG points.

PM1
In a hotspot region, there are 23 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 7 uncertain in NM_001374258.1
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr7-140753346-G-C is described in ClinVar as Pathogenic. ClinVar VariationId is 13969.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.945
PP5
Variant 7-140753345-A-C is Pathogenic according to our data. Variant chr7-140753345-A-C is described in ClinVar as Pathogenic. ClinVar VariationId is 13968.Status of the report is no_assertion_criteria_provided, 0 stars.
