Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.968C>T (p.Ser323Leu) variant in the BRAF gene is 0.06% for South Asian chromosomes by the Exome Aggregation Consortium (17/16512 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1).

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]

Variant classified as Uncertain Significance - Favor Benign. The Ser323Leu varia nt has not been reported in the literature nor previously identified by our labo ratory. Serine (Ser) at this position is conserved across mammals but not into lower species and computational analyses (biochemical amino acid properties, Pol yPhen2, SIFT, AlignGVGD) do not provide strong support for or against pathogenic ity. In the absence of additional information, the clinical significance of thi s variant cannot be determined at this time. -
