The NM_000051.4(ATM):c.6067G>A (p.Gly2023Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The gene ATM is a tumor suppressor gene (CancerMine: 26 TSG, 31 oncogene, 24 driver citations). The gene ATM is a known oncogene (CancerMine: 26 TSG, 31 oncogene, 24 driver citations). The gene ATM is a cancer driver gene (CancerMine: 26 TSG, 31 oncogene, 24 driver citations). The variant allele was found at a cumulative frequency of 0.00155 (AC=2,496) in the gnomAD database across 1,612,772 control chromosomes, including 4 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.00197. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 9.47). Variant has been reported in ClinVar as Benign/Likely Benign (no review stars). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.G2023E: Uncertain_significance (ClinVar VariationId 453610, 2 stars); p.G2023= (synonymous): Likely_benign (ClinVar VariationId 1751358, 1 star); p.G2023R: Benign (ClinVar VariationId 2127852, 1 star); p.G2023V: Uncertain_significance (ClinVar VariationId 3801988, 1 star) The variant has been observed in cBioPortal in 7 samples across 6 studies and 6 cancer types; somatic enrichment level: SUPPORTING (Observed repeatedly in cBioPortal somatic datasets.). This exact variant is curated in the UniProt human variants database as Uncertain Significance, associated with Ataxia telangiectasia (AT).

Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Specifications for ATM are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 0 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O4Enriched in somatic variant database		Enriched in cBioPortal (pre-computed score ≥ 1.0) — Supporting (O4); cBioPortal: samples=7 | studies=6 | cancer types=6 | level=SUPPORTING | points=1.0 | reason: Observed repeatedly in cBioPortal somatic datasets.
	B2Does not fit gene mode of action		Activating variant in tumor suppressor gene + same AA change classified germline Benign/Likely Benign — supporting benign evidence (B2, no cancer-type context); Activating variant in tumor suppressor gene + same AA change classified germline Benign/Likely Benign — supporting benign evidence (B2, no cancer-type context)
