Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP2PP3PP5
The NM_001374258.1(BRAF):c.1909_1910delinsTC(p.Leu637Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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 made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM1
?
In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 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 id is 13969.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP2
?
Missense variant where missense usually causes diseases, BRAF
PP3
?
No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
PP5
?
Variant 7-140753345-AG-GA is Pathogenic according to our data. Variant chr7-140753345-AG-GA is described in ClinVar as [Pathogenic]. Clinvar id is 375942.Status of the report is no_assertion_criteria_provided, 0 stars.
