Ambry Genetics RCV000185637 SCV000186502 pathogenic Hereditary cancer-predisposing syndrome 2021-07-29 criteria provided, single submitter clinical testing The c.7638_7646delTAGAATTTC pathogenic mutation (also known as p.R2547_S2549del), located in coding exon 51 of the ATM gene, results from an in-frame deletion of 9 nucleotides between positions 7638 and 7646. This results in the deletion of 3 amino acids between codons 2547 and 2549. This pathogenic mutation has been reported in individuals diagnosed with breast cancer, some of whom also had family histories of other cancers (Vorechovsky I et al. Cancer Res. 1996 Sep;56:4130-3; Goldgar DE et al. Breast Cancer Res. 2011 Jul;13:R73). In addition, this mutation has been reported in a homozygous state and in conjunction with other deleterious ATM mutations in multiple individuals and/or families with ataxia-telagiectasia (Gilad S et al. Hum. Mol. Genet. 1996 Apr;5:433-9; Wright J et al. Am. J. Hum. Genet. 1996 Oct;59:839-46; Watters D et al. Oncogene. 1997 Apr;14:1911-21; Telatar M et al. Am. J. Hum. Genet. 1998 Jan;62:86-97; Stankovic T et al. Am. J. Hum. Genet. 1998 Feb;62:334-45; Li A and Swift M. Am. J. Med. Genet. 2000 May;92:170-7; Buzin C et al. Hum. Mutat. 2003 Feb;21:123-31). Further, functional analysis has shown that this mutation results in intact ATM protein expression but no kinase activity (Stewart GS et al. J. Biol. Chem. 2001 Aug;276:30133-41). Of note, this alteration is also designated as 7636del9, 2546delSRI, 7638del9 and 7638_7646del9 in published literature. Based on the available evidence, this alteration is interpreted as a disease-causing mutation.

Invitae RCV000206671 SCV000262210 pathogenic Ataxia-telangiectasia syndrome 2024-01-31 criteria provided, single submitter clinical testing This variant, c.7638_7646del, results in the deletion of 3 amino acid(s) of the ATM protein (p.Arg2547_Ser2549del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs587776547, gnomAD 0.007%). This variant has been observed in individuals with breast cancer and ataxia-telangiectasia (PMID: 7792600, 8797579, 11382771, 12552559, 21787400, 22649200). This variant is also known as 7636del9 and 7638del9. ClinVar contains an entry for this variant (Variation ID: 3019). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects ATM function (PMID: 11382771, 12195425, 19431188, 22649200). For these reasons, this variant has been classified as Pathogenic.

This variant is also known as 7636del9, 7637del9 and delSRI in the literature. Functional studies have reported the mutant protein to show a severely defective kinase activity (PMID: 11382771, 19431188, 21778326, 22649200). This variant has been reported in over ten heterozygous individuals affected with breast cancer (PMID: 9288106, 16652348, 21787400; Color internal data) and pancreatic cancer (PMID: 33439686; Color internal data). This variant has been observed in homozygous and compound heterozygous states in over a dozen individuals affected with autosomal recessive ataxia-telangiectasia, indicating that this variant contributes to disease (PMID: 7792600, 8755918, 8845835, 8808599, 9443866, 9463314, 10817650). This variant is reported to be a founder mutation in individuals of Irish and British ancestry (PMID: 9443866, 9463314). This variant has been identified in 7/251148 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Pathogenic.
PreventionGenetics, part of Exact Sciences RCV004547454 SCV000805616 pathogenic ATM-related disorder 2023-12-19 criteria provided, single submitter clinical testing The ATM c.7638_7646del9 variant is predicted to result in an in-frame deletion (p.Arg2547_Ser2549del). This variant is also known in the literature as c.7636del9. This variant has been reported in patients with ataxia telangiectasia (Savitsky et al. 1995. PubMed ID: 7792600), prostate cancer (Supplemental Table 1 in Na et al. 2017. PubMed ID: 27989354), and breast cancer (Vorechovský et al. 1996. PubMed ID: 8797579; Chen et al. 1998. PubMed ID: 9537233; Lu et al. 2019. PubMed ID: 30128536, eTable 12; Goldgar et al. 2011. PubMed ID: 21787400). In vitro functional analysis showed that this variant had no kinase activity (Barone et al. 2009. PubMed ID: 19431188). This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD and is interpreted as likely pathogenic/pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/3019/). This variant is interpreted as pathogenic.
Human Genome Sequencing Center Clinical Lab, Baylor College of Medicine RCV000709706 SCV000839880 likely pathogenic Familial cancer of breast 2017-04-03 criteria provided, single submitter clinical testing This c.7638_7646del (p.Arg2547_Ser2549del) has previously been reported in compound heterozygous and homozygous patients with ataxia telangiectasia [PMID 8808599]. Functional assays showed that the variant does not affect the level of ATM protein but does reduce the level of kinase activity [PMID 19431188]. A mouse model carrying this deletion has an increase susceptibility to develop tumors [reported as 7636del9 in PMID 12195425]. This variant was further detected in 12 out of 294 families with breast cancer. However, the difference in tumor incidence between carrier and non carrier was not statistically significant. However, this variant was detected in another patient with breast cancer [PMID 8797579]. This c.7638_7646del (p.Arg2547_Ser2549del) variant has not been observed the ExAC population database and has been observed in one individual in our internal database. It is thus interpreted as a likely pathogenic variant.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000206671 SCV000916557 pathogenic Ataxia-telangiectasia syndrome 2017-10-27 criteria provided, single submitter clinical testing Variant summary: The ATM c.7638_7646delTAGAATTTC (p.Arg2547_Ser2549del) variant involves the inframe deletion of 9 nucleotides located in the PIK-related kinase domain (IPR014009) (InterPro). One in silico tool predicts a damaging outcome for this variant. Functional studies confirmed that there is no detectable ATM kinase activity associated with this variant and that LCLs with this variant exhibited p53, p21, and MDM2 response that was indistinguishable from classical A-T (Stewart_2001). This variant was found in 5/246251 control chromosomes at a frequency of 0.0000203, which does not exceed the estimated maximal expected allele frequency of a pathogenic ATM variant (0.0039528). This variant was reported in multiple AT patients (Stankovic_1998, Skowronska_2012, Stewart_2001). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.

Department of Pathology and Laboratory Medicine, Sinai Health System RCV001355331 SCV001550193 pathogenic Malignant tumor of breast no assertion criteria provided clinical testing The ATM p.Arg2547_Ser2549del variant was identified in 14 of 6042 proband chromosomes (frequency: 0.002) from individuals or families with Ataxia-telangiectasia and breast cancer (Buzin 2003, Goldgar 2011, Li 2000, Reiman 2011). The variant was also identified in the following databases: dbSNP (ID: rs587776547) as "With Pathogenic allele", ClinVar (9x pathogenic, 1x uncertain significance), Clinvitae (5x pathogenic, 1x uncertain significance), Cosmic (1x, haematopoietic and lymphoid tumour), and the LOVD 3.0 (27x). The variant was not identified in the MutDB database. The variant was not identified in the 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). Multiple functional studies have shown the ATM protein lacks kinase activity and is expressed at low levels, confirming the pathogenicity of this variant (Barone 2009, Reiman 2011). This variant is an in-frame deletion resulting in the removal of three residues, from codon 2547 to 2549. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic.
