Position:

• chrX-47566721-T-A

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PM5

The NM_001654.5(ARAF):​c.640T>A​(p.Ser214Thr) 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. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S214A) has been classified as Likely pathogenic.

• Frequency: Genomes: not found (cov: 23)
• Consequence: ARAF NM_001654.5 missense
• Clinical Significance: Not reported in ClinVar
• 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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrX-47566721-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376367.Status of the report is no_assertion_criteria_provided, 0 stars.
