GeneDx RCV000588523 SCV000149167 uncertain significance not provided 2018-10-19 criteria provided, single submitter clinical testing This variant is denoted ATM c.7928-10T>C or IVS53-10T>C and consists of a T>C nucleotide substitution at the -10 position of intron 53 of the ATM gene. In silico analyses, which include splice predictors and evolutionary conservation, are inconsistent in their assessment as to whether or not the variant is damaging. This variant has been reported in one individual with breast cancer (Decker 2017). ATM c.7928-10T>C was observed at an allele frequency of 0.23% (56/24,028) in individuals of African ancestry in large population cohorts (Lek 2016). Based on currently available evidence, it is unclear whether ATM c.7928-10T>C is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Integrated Genetics/Laboratory Corporation of America RCV000588523 SCV000694365 uncertain significance not provided 2017-02-16 criteria provided, single submitter clinical testing Variant summary: The ATM c.7928-10T>C variant involves the alteration of a conserved intronic nucleotide and 4/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 23/121240 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.002033 (21/10330). This frequency is about 2 times the estimated maximal expected allele frequency of a pathogenic ATM variant (0.0010005), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. The variant of interest has not, to our knowledge, been reported in affected individuals via publications. Clinical diagnostic laboratories have classified this variant with conflicting classifications as uncertain significance (1) as well as benign (1). Therefore, this variant has been classified as a "Variant of Uncertain Significance - Possibly Benign."
