Ambry Genetics | RCV000115144 | SCV000185620 | pathogenic | Hereditary cancer-predisposing syndrome | 2024-10-23 | criteria provided, single submitter | clinical testing | The c.1564_1565delGA pathogenic mutation, located in coding exon 9 of the ATM gene, results from a deletion of two nucleotides at nucleotide positions 1564 to 1565, causing a translational frameshift with a predicted alternate stop codon (p.E522Ifs*43). This alteration is a commonly recurring mutation in Ataxia-Telangiectasia cohorts and has been observed in both the homozygous and compound heterozygous states (Byrd PJ et al. Hum. Mol. Genet. 1996 Jan;5:145-9; McConville CM et al. Am. J. Hum. Genet. 1996 Aug;59:320-30; Broeks A et al. Hum. Mutat. 1998;12:330-7; Stankovic T et al. Am. J. Hum.

Genet. 2000 May;92:170-7; Verhagen MM et al. Neuropediatrics. 2007 Jun;38:117-21; Verhagen MM et al. Neurology. 2009 Aug;73:430-7; Reiman A et al. Br. J. Cancer. 2011 Aug;105:586-91; Demuth I et al. Neurogenetics. 2011 Nov;12:273-82; Verhagen MM et al. Hum. Mutat. 2012 Mar;33:561-71; van Os NJH et al. Clin. Immunol. 2017 05;178:45-55). This mutation has also been observed in patients with breast cancer (Hansford S et al. JAMA Oncol. 2015 Apr;1:23-32; Seifert BA et al. Clin. Cancer Res. 2016 Aug;22:4087-4094; Decker B et al. J. Med. Genet. 2017 Nov;54:732-741; Hauke J et al. Cancer Med. 2018 Apr;7:1349-1358). Additionally, this mutation has been identified in multiple cohorts of patients with pancreatic cancer (Shindo K et al. J. Clin. Oncol. 2017 Oct;35:3382-3390; Young EL et al. BMC Cancer. 2018 Jun;18:697; Dudley B et al. Cancer. 2018 Apr;124:1691-1700; Brand R et al. Cancer. 2018 Aug;[Epub ahead of print]). Of note, this alteration is also designated as 1560CAG>C, 1561delAG, 1561_1562delAG, 1563delAG, and 1563_1564delAG in published literature. In addition to the clinical data presented in the literature, 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. |

RCV000115144 | SCV000821698 | pathogenic | Hereditary cancer-predisposing syndrome | 2020-01-01 | criteria provided, single submitter | clinical testing | This variation is a deletion of 2 nucleotides in exon 10 of the ATM mRNA (c.1564_1565delGA), causing a frameshift after codon 522 and the creation of a premature translational stop signal 43 amino acid residues later -p.(Glu522Ilefs*43). This is expected to result in an absent or disrupted protein product. Truncating variants in ATM are known to be pathogenic. This particular variant has been reported in the literature in individuals affected with ataxia-telangiectasia and in breast cancer patients (PMID: 10817650, PMID: 12497634, PMID: 27083775). The mutation database ClinVar contains multiple entries for this variant (Variation ID: 127340). |

RCV000169147 | SCV000918549 | pathogenic | Ataxia-telangiectasia syndrome | 2018-07-09 | criteria provided, single submitter | clinical testing | Variant summary: ATM c.1564_1565delGA (p.Glu522IlefsX43) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 5.3e-05 in 246034 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in ATM causing Ataxia-Telangiectasia (5.3e-05 vs 0.004), allowing no conclusion about variant significance. The variant, c.1564_1565delGA, has been reported in the literature in multiple individuals affected with Ataxia-Telangiectasia (Demuth_2011, Stankovic_1998, Sandoval_199). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submission from clinical diagnostic laboratories (evaluation after 2014) cites the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
Athena Diagnostics | RCV000211964 | SCV001143097 | pathogenic | not provided | 2020-11-18 | criteria provided, single submitter | clinical testing | This variant is expected to result in the loss of a functional protein. The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in at least one individual with clinical features associated with this gene. In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. |

RCV001357511 | SCV001553000 | pathogenic | Malignant tumor of breast | no assertion criteria provided | clinical testing | The ATM p.Glu522Ilefs*43 variant was identified in 24 of 22060 proband chromosomes (frequency: 0.002) from individuals or families with Ataxia-Telangiectasia, breast cancer, melanoma, or pancreatic cancer (Campbell 2003, Demuth 2011, Li 2000, Seifert 2016, Stankovic 1998, Susswein 2015, Teraoka 1999, Verhagen 2011, Mitu 2005). The variant was also identified in dbSNP (ID: rs587779817; Alias rs751357509) as "With Pathogenic allele", ClinVar (classified as pathogenic by GeneDx, Ambry Genetics, Invitae, Counsyl, Color Genomics and Center for Pediatric Genomic Medicine, Children's Mercy Hospital and Clinics), Cosmic (2x found in Haematopoietic and lymphoid tissue or Upper aerodigestive tract), and LOVD 3.0 (40x as pathogenic). The variant was not identified in the COGR database. The variant was not identified in the following control databases: the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The c.1564_1565del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 522 and leads to a premature stop codon at position 564. This alteration is then predicted to result in a truncated or absent protein and loss of function. Loss of function variants of the ATM gene are an established mechanism of disease in ATM-associated cancers and is the type of variant expected to cause the disorder. In summary, based on the above information, this variant meets our laboratory’s criteria to be classified as pathogenic. | |
