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

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.762

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1963 of the ATM protein (p.Asp1963Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with ATM-related conditions (PMID: 33436325). ClinVar contains an entry for this variant (Variation ID: 219542). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Collection Method: clinical testing

The ATM c.5887G>A variant is predicted to result in the amino acid substitution p.Asp1963Asn. This variant was reported as a variant of uncertain significance in an individual with prostate cancer (Table S4, Karlsson et al. 2021. PubMed ID: 33436325). This variant has not been reported in a large population database, indicating this variant is rare. This variant has been interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/219542/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

The p.D1963N variant (also known as c.5887G>A), located in coding exon 38 of the ATM gene, results from a G to A substitution at nucleotide position 5887. The aspartic acid at codon 1963 is replaced by asparagine, an amino acid with highly similar properties. This alteration has been reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J. Med. Genet., 2017 11;54:732-741). This variant was also reported in 1/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 Aug;4:570-579). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
