This alteration is classified as benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

The ATM c.5497-8T>C variant was identified in 37 of 1416 proband chromosomes (frequency: 0.026) from individuals or families with breast cancer (Concannon 2008, Paglia 2010). The variant was also identified in dbSNP (ID: rs3092829) as “With Benign allele”, ClinVar (5x, as benign by Invitae, Ambry Genetics, Vantari, PreventionGenetics, Color Genomics), Clinvitae (3x, as benign), Cosmic (4x, in ovary carcinoma, and soft tissue Haemangioblastoma), LOVD 3.0 (1x with "does not affect function"), databases. The variant was not identified in GeneInsight-COGR, MutDB and ATM-LOVD, databases. The variant was identified in control databases in 6238 (94 homozygous) of 276468 chromosomes at a frequency of 0.0225 increasing the likelihood this could be a benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: European (Non-Finnish) in 4209 (69 homozygous) of 126224 chromosomes (freq: 0.033), other in 181 (3 homozygous) of 6446 chromosomes (freq: 0.028), European (Finnish) in 650 (10 homozygous) of 25722 chromosomes (freq: 0.025), Ashkenazi Jewish* in 236 (4 homozygous) of 10138 chromosomes (freq: 0.023), Latino in 631 (7 homozygous) of 34354 chromosomes (freq: 0.018). The c.5497-8T>C variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. However, positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. However, 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 benign. (less)

Comment:
Comment:
This variant is considered benign. This variant is intronic and is not expected to impact mRNA splicing. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance.
Comment:
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign.
Comment:
The ATM c.5497-8T>C variant was identified in 37 of 1416 proband chromosomes (frequency: 0.026) from individuals or families with breast cancer (Concannon 2008, Paglia 2010). The variant was also identified in dbSNP (ID: rs3092829) as “With Benign allele”, ClinVar (5x, as benign by Invitae, Ambry Genetics, Vantari, PreventionGenetics, Color Genomics), Clinvitae (3x, as benign), Cosmic (4x, in ovary carcinoma, and soft tissue Haemangioblastoma), LOVD 3.0 (1x with "does not affect function"), databases. The variant was not identified in GeneInsight-COGR, MutDB and ATM-LOVD, databases. The variant was identified in control databases in 6238 (94 homozygous) of 276468 chromosomes at a frequency of 0.0225 increasing the likelihood this could be a benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: European (Non-Finnish) in 4209 (69 homozygous) of 126224 chromosomes (freq: 0.033), other in 181 (3 homozygous) of 6446 chromosomes (freq: 0.028), European (Finnish) in 650 (10 homozygous) of 25722 chromosomes (freq: 0.025), Ashkenazi Jewish* in 236 (4 homozygous) of 10138 chromosomes (freq: 0.023), Latino in 631 (7 homozygous) of 34354 chromosomes (freq: 0.018).

The variant was also identified in dbSNP (ID: rs3092829) as “With Benign allele”, ClinVar (5x, as benign by Invitae, Ambry Genetics, Vantari, PreventionGenetics, Color Genomics), Clinvitae (3x, as benign), Cosmic (4x, in ovary carcinoma, and soft tissue Haemangioblastoma), LOVD 3.0 (1x with "does not affect function"), databases. The variant was not identified in GeneInsight-COGR, MutDB and ATM-LOVD, databases. The variant was identified in control databases in 6238 (94 homozygous) of 276468 chromosomes at a frequency of 0.0225 increasing the likelihood this could be a benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: European (Non-Finnish) in 4209 (69 homozygous) of 126224 chromosomes (freq: 0.033), other in 181 (3 homozygous) of 6446 chromosomes (freq: 0.028), European (Finnish) in 650 (10 homozygous) of 25722 chromosomes (freq: 0.025), Ashkenazi Jewish* in 236 (4 homozygous) of 10138 chromosomes (freq: 0.023), Latino in 631 (7 homozygous) of 34354 chromosomes (freq: 0.018). The c.5497-8T>C variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. However, positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. However, 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 benign.
Germline Functional Evidence
| There is no functional evidence in ClinVar for this variation. If you have generated functional data for this variation, please consider submitting that data to ClinVar. |
Comment:
This alteration is classified as benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
Comment:
This variant is considered benign. This variant is intronic and is not expected to impact mRNA splicing. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance.
Comment:
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign.
Comment:
The ATM c.5497-8T>C variant was identified in 37 of 1416 proband chromosomes (frequency: 0.026) from individuals or families with breast cancer (Concannon 2008, Paglia 2010). The variant was also identified in dbSNP (ID: rs3092829) as “With Benign allele”, ClinVar (5x, as benign by Invitae, Ambry Genetics, Vantari, PreventionGenetics, Color Genomics), Clinvitae (3x, as benign), Cosmic (4x, in ovary carcinoma, and soft tissue Haemangioblastoma), LOVD 3.0 (1x with "does not affect function"), databases.

Record last updated Nov 25, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
