Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_StrongBP6BP7
The NM_000051.4(ATM):c.591A>T(p.Gly197Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000236 in 1,613,484 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. G197G) has been classified as Likely benign.

Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:1Benign:2
- -
- -
This alteration is classified as likely 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 is a silent/synonymous amino acid change and it is not expected to impact splicing. -

Malignant tumor of breast Uncertain:1
The ATM p.Gly197= variant was not identified in the literature nor was it identified in the LOVD 3.0 databases. The variant was identified in dbSNP (rs587780630) as “with likely benign allele”, ClinVar (interpreted as "likely benign" by Invitae and 3 others). The variant was identified in control databases in 9 of 245,816 chromosomes at a frequency of 0.00004 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 2 of 5460 chromosomes (freq: 0.0004), European in 5 of 111,480 chromosomes (freq: 0.00005), and South Asian in 2 of 30,772 chromosomes (freq: 0.00007). The variant was not observed in the African, Latino, Ashkenazi Jewish, East Asian and Finnish populations. The p.Gly197= 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. The variant occurs at a non-conserved nucleotide outside of the splicing consensus sequence and 1 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing, predicting the creation of a new 3’ splice site; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
