This variant is denoted ATM c.4396C>G at the cDNA level, p.Arg1466Gly (R1466G) at the protein level, and results in the change of an Arginine to a Glycine (CGA>GGA). This variant has been observed in at least two individuals with breast cancer and one healthy control (Tung 2015, Decker 2017, Tiao 2017). ATM Arg1466Gly was not observed at a significant allele frequency in large population cohorts (Lek 2016). ATM Arg1466Gly is not located within a known functional domain. In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether ATM Arg1466Gly is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
