Ataxia-telangiectasia syndrome Benign:5
- -
- -
- -
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. -

Hereditary cancer-predisposing syndrome Benign:5
- -
- -
- -
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. -

Familial cancer of breast Benign:2
This variant is considered benign. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -

Malignant tumor of breast Benign:1
The ATM p.Ile2030Val variant was identified in 5 of 3368 proband chromosomes (frequency: 0.001) from individuals or families with breast cancer or lynch syndrome and was present in 1 of 162 control chromosomes (Ho 2017, Iannuzzi 2002, Teraoka 2001, Yorczyk 2015, Yurgelun 2015). The variant was also identified in dbSNP (ID: rs145847315) as “With other allele”, ClinVar (as benign by Invitae, GeneDx, Ambry Genetics, EDL Genetic Diagnostics, University of Chicago, and Color Genomics, and as likely benign by Counsyl, and Institute for Biomarker Research), Clinvitae (4x), databases. The variant was not identified in Cosmic, MutDB, LOVD 3.0, or ATM-LOVD databases. The variant was identified in control databases in 444 of 277186 chromosomes (6 homozygous) at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 417 of 24038 chromosomes (freq: 0.02), Other in 4 of 6466 chromosomes (freq: 0.001), Latino in 19 of 34416 chromosomes (freq: 0.001), European in 4 of 126698 chromosomes (freq: 0.00003), while the variant was not observed in the Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Ile2030 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
