Classification rationale
1

The BRAF c.793G>C (p.Gly265Arg) variant has been observed in somatic cancer once in COSMIC and has been reported in ClinVar with an expert panel likely pathogenic classification and additional pathogenic or likely pathogenic clinical laboratory submissions.

This variant is absent from gnomAD v2.1 and gnomAD v4.1, supporting rarity in population reference datasets.

Computational evidence supports a damaging missense effect, with REVEL 0.917 above the BRAF RASopathy PP3 threshold of 0.7, BayesDel 0.403109 in a deleterious direction, and SpliceAI showing no significant predicted splice impact (maximum delta score 0.00).

ClinVar evidence

ClinVar
This variant has been reported in ClinVar as Likely pathogenic (2 clinical laboratories) and as Pathogenic (1 clinical laboratory) and as Likely pathogenic by ClinGen RASopathy Variant Curation Expert Panel (expert panel).

OncoKB: Unknown Oncogenic Effect
OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. BRAF, an intracellular kinase, is frequently mutated in melanoma, thyroid and lung cancers among others.
