The NM_000051.4(ATM):c.6067G>C (p.Gly2023Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. 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 (★). 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: Conflicting_classifications_of_pathogenicity (ClinVar VariationId 127416); p.G2023V: Uncertain_significance (ClinVar VariationId 3801988, 1 star) 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 ACMG Germline Pathogenicity v2019

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 1 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM1Mutational hot spot or critical domain		Missense neighbourhood moderate hotspot (≥2 P/LP within ±8 AA, OR ≥ 2 vs. background) — PM1 supporting; In-domain: 0 pathogenic, 0 benign rare missense variants.; ±8 AA neighbourhood: 2 pathogenic, 4 benign (OR vs. background: 2.8).
	PM2Absent/extremely low in population databases		Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (threshold 0.0001) — PM2 moderate.
	BP6Reputable source reports benign		ClinVar 1-star benign — moderate (BP6); ClinVar germline classification: Benign/Likely Benign, 1 star(s).
