Submissions by phenotype
not specified Benign:5
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
The ATM p.Thr1389= variant was not identified in the literature nor was it identified in the Genesight-COGR, Cosmic, MutDB, LOVD 3.0, ATM-LOVD, databases. The variant was identified in dbSNP (ID: rs183214437) as “with other allele”, in ClinVar and Clinvitae databases as benign by GeneDx and Ambry Genetics; and likely benign by Invitae, and Color Genomics Inc.). The variant was identified in control databases in 29 of 277012 chromosomes at a frequency of 0.0001 in the following populations: African in 1 of 24024 chromosomes (freq. 0.00004), Latino in 7 of 34400 chromosomes (freq. 0.0002), European Non-Finnish in 18 of 126560 chromosomes (freq. 0.0001), Other in 3of 6458 chromosomes (freq. 0.0005), but was not seen in Ashkenazi Jewish, East Asian , European Finnish, and South Asian populations, increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The p.Thr1389= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, 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.
Hereditary cancer-predisposing syndrome Benign:4
This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, 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.
Ataxia-telangiectasia syndrome Benign:2
not provided Benign:2
ATM: BP4, BP7
Familial cancer of breast Benign:1
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing.
