Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PS3 PM1 PP3_Strong PP5_Very_Strong

The NM_000051.4(ATM):​c.8737G>T​(p.Asp2913Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000116 in 1,461,830 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000274516: Cell lines from an individual diagnosed with ataxia telangiectasia who was heterozygous for this alteration along with a second alteration in ATM, exhibited decreased response to ionizing radiation, decreased ATM protein expression, and abnormal cellular localization (Jacquemin V et al. Eur. J. Hum. Genet. 2012 Mar" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D2913E) has been classified as Uncertain significance. 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]

C11orf65 (HGNC:28519): (chromosome 11 open reading frame 65) Predicted to be involved in negative regulation of mitochondrial fission and negative regulation of protein targeting to mitochondrion. Predicted to be located in cytosol and mitochondrial outer membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000274516: Cell lines from an individual diagnosed with ataxia telangiectasia who was heterozygous for this alteration along with a second alteration in ATM, exhibited decreased response to ionizing radiation, decreased ATM protein expression, and abnormal cellular localization (Jacquemin V et al. Eur. J. Hum. Genet. 2012 Mar;20(3):305-12).; SCV001341304: Functional studies have shown that this variant results in reduced protein expression, abnormal sub-cellular localization, and disrupted phosphorylation activity (PMID: 22071889, 31050087).; SCV000942483: Experimental studies have shown that this missense change affects ATM function (PMID: 22071889, 31050087).; SCV001821316: Experimental evidence evaluating an impact on protein function demonstrated that the variant results in reduced protein expression, while it alters subcellular localization and cell cycle distribution and it impairs phosphorylation of target proteins such as H2AX, CHK2 and KAP1 (Jacquemin_2012, Fievet_2019).; SCV004020282: Functional studies indicate this variant impacts protein function [PMID: 22071889, 31050087].
• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 46 uncertain in NM_000051.4
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.957
• PP5: Variant 11-108353831-G-T is Pathogenic according to our data. Variant chr11-108353831-G-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 230841.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
