Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PS3PM2PP3PP5

The NM_000051.4(ATM):c.4801A>G(p.Ser1601Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,574 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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: "SCV000278017: RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data).". Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1601N) has been classified as Likely benign.

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

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000278017: RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data).

PM2

Very rare variant in population databases, with high coverage;

PP3

Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

PP5

Variant 11-108294951-A-G is Pathogenic according to our data. Variant chr11-108294951-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 233609.
