The variant received 5 classification points (ACGS-UK Somatic Oncogenicity v2025). O1_StrongO3_Supporting

The NM_007373.4(SHOC2):c.4A>G (p.Ser2Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The gene SHOC2 is a known oncogene (CancerMine: 2 oncogene, 1 driver citations). The gene SHOC2 is a cancer driver gene (CancerMine: 2 oncogene, 1 driver citations). The variant allele was found at a cumulative frequency of 0.00000342 (AC=5) in the gnomAD database across 1,460,838 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000147. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 8.49). Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★★★). ClinVar reports functional evidence for this variant: "SCV000605107: Functional characterization of the p.Ser2Gly protein indicates enhanced myristoylation, and aberrant targeting of the SHOC2 to the cell membrane in the absence of growth factor signaling (Cordeddu 2009). PMID:19684605" and additional evidence is available in ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.S2T: Uncertain_significance (ClinVar VariationId 2265459, 1 star) This exact variant is established as oncogenic in: CGI (Cancer Genome Interpreter). The variant has been observed in cBioPortal in 3 samples across 2 studies and 3 cancer types; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.). This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Genes affected

SHOC2 (HGNC:15454): (SHOC2 leucine rich repeat scaffold protein) This gene encodes a protein that consists almost entirely of leucine-rich repeats, a domain implicated in protein-protein interactions. The protein may function as a scaffold linking RAS to downstream signal transducers in the RAS/ERK MAP kinase signaling cascade. Mutations in this gene have been associated with Noonan-like syndrome with loose anagen hair. [provided by RefSeq, May 2010]
