Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 7P and 1B. PS3PM2PP5BP4

The NM_000051.4(ATM):c.680C>T(p.Ser227Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,613,418 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/24 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV000935774: Studies have shown that this missense change results in skipping of exon 7, and produces a non-functional protein and/or introduces a premature termination codon (internal data)." and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. S227S) has been classified as Likely benign. The gene ATM is included in the ClinGen Criteria Specification Registry.

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]

ACMG classification

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: Likely_pathogenic. The variant received 6 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000935774: Studies have shown that this missense change results in skipping of exon 7, and produces a non-functional protein and/or introduces a premature termination codon (internal data).; SCV002499809: RNA studies demonstrate a damaging effect: aberrant splicing leading to out-of-frame exon skipping, resulting in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease (External communication with an outside laboratory); PMID: 33436325, 26689913, 38649916

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 11-108244805-C-T is Pathogenic according to our data. Variant chr11-108244805-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 485170.

BP4

Computational evidence support a benign effect (MetaRNN=0.15308997). . Strength limited to SUPPORTING due to the PP5.
