X-47566722-C-T

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PM5 PP3 PP5

The NM_001654.5(ARAF):c.641C>T(p.Ser214Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S214A) has been classified as Likely pathogenic.

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 Likely_pathogenic. Variant got 6 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.792
• PP5: Variant X-47566722-C-T is Pathogenic according to our data. Variant chrX-47566722-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376366.Status of the report is no_assertion_criteria_provided, 0 stars.
