The NM_001654.5(ARAF):​c.640T>G​(p.Ser214Ala) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 23)
• Consequence: ARAF NM_001654.5 missense
• Clinical Significance: Likely pathogenic no assertion criteria provided P:3
• Conservation: PhyloP100: 6.02

Genes affected

ARAF (HGNC:646): (A-Raf proto-oncogene, serine/threonine kinase) Enables protein serine/threonine kinase activity. Involved in negative regulation of apoptotic process; regulation of TOR signaling; and regulation of cellular protein metabolic process. Predicted to be active in cytosol and mitochondrion. Biomarker of high grade glioma. [provided by Alliance of Genome Resources, Apr 2022]
