Variant summary
Our verdict is Benign. Variant got -11 ACMG points: 0P and 11B. BP4_ModerateBP6_Very_StrongBP7
The NM_000051.4(ATM):c.103C>A(p.Arg35Arg) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000483 in 1,613,574 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 Likely benign (★★).

Variant summary: ATM c.103C>A alters a non-conserved nucleotide resulting in a synonymous change. Consensus agreement among computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 9.9e-05 in 282600 control chromosomes (gnomAD), predominantly at a frequency of 0.00088 within the African or African-American subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in ATM causing Breast Cancer (9.9e-05 vs 0.001), allowing no conclusion about variant significance. c.103C>A has been reported in the literature without evidence for causality (e.g. Gumy Pause_2003, Bernstein_2010). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 20305132, 12673804). Ten ClinVar submitters have assessed the variant since 2014: one classified the variant as benign, and nine as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -

Hereditary cancer-predisposing syndrome Benign:3
- -
- -
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. -
