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 Pathogenic. Variant got 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-108317446-G-A is Pathogenic according to our data. Variant chr11-108317446-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 407735.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Hereditary cancer-predisposing syndrome Pathogenic:2

Jan 28, 2025

Molecular Diagnostics Laboratory, Catalan Institute of Oncology

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

PVS1, PM2_supporting, PM5_supporting c.6272G>A, located in exon 43 of the ATM gene, is a nonsense variant expected to result in loss of function by premature protein truncation and nonsense-mediated mRNA decay (PVS1). It is not present in the population database gnomAD v2.1.1, non-cancer dataset (PM2_supporting). To our knowledge, neither relevant clinical data nor well-established functional studies have been reported for this variant. This variant has been reported in the ClinVar database (3x pathogenic) and has not been reported in LOVD. The premature termination codon is upstream of p.Arg3047* which is the most C-terminal pathogenic variant (PM5_Supporting). Based on currently available information, the variant cc.6272G>A should be considered a pathogenic variant according to ACMG Classification Rules Specified for ATM v1.1. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.W2091* pathogenic mutation (also known as c.6272G>A), located in coding exon 42 of the ATM gene, results from a G to A substitution at nucleotide position 6272. This changes the amino acid from a tryptophan to a stop codon within coding exon 42. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

Ataxia-telangiectasia syndrome Pathogenic:1

Mar 08, 2023

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Trp2091*) in the ATM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 407735). For these reasons, this variant has been classified as Pathogenic. -
