Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6
The ENST00000531525.3(ATM):c.*111G>A variant causes a 3 prime UTR change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,558 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).

Submissions by phenotype
not provided Uncertain:2
Not observed at a significant frequency in large population cohorts (Lek 2016); In-silico analysis is inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; Observed in individuals with a personal history of colorectal cancer in published literature (Yurgelun 2017); This variant is associated with the following publications: (PMID: 28135145) -

Hereditary cancer-predisposing syndrome Benign: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. -
not specified Uncertain:1
Variant summary: ATM c.4909+3G>A alters a conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. One computational tool predicts that the variant strengthens a 5 donor site. However, this prediction have yet to be confirmed by functional studies. The variant allele was found at a frequency of 1.6e-05 in 251304 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.4909+3G>A has been reported in the literature in an individual affected with colorectal cancer (Yurgelun_2017). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, 3 classifying the variant as VUS, and 1 calling it as likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Familial cancer of breast Benign:1
This variant is considered benign. This variant is intronic and is not expected to impact mRNA splicing. 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]. -
