Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PS3 PM1 PM2 PP3_Moderate PP5_Very_Strong

The NM_000051.4(ATM):​c.8030A>G​(p.Tyr2677Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,240 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000622797: Experimental studies have shown that this missense change affects ATM function (PMID:11826028, 18634022)." and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y2677F) 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: SCV000622797: Experimental studies have shown that this missense change affects ATM function (PMID: 11826028, 18634022).; SCV001189592: Functional studies in patient derived cells showed that although this variant results in significantly reduced protein levels (Saviozzi S et al. J. Med. Genet., 2002 Jan;39:57-61; Mitui M et al. Hum Mutat 2009 Jan;30(1):12-21), its ability to phosphorylate its targets were close to normal levels (Saviozzi S et al. J. Med. Genet., 2002 Jan;39:57-61).; SCV004933089: Functional studies indicate this variant impacts protein function [PMID: 18634022, 11826028].
• PM1: In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 34 uncertain in NM_000051.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.916
• PP5: Variant 11-108334988-A-G is Pathogenic according to our data. Variant chr11-108334988-A-G is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3045.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
