This variant is denoted ATM c.1855A>C at the cDNA level, p.Asn619His (N619H) at the protein level, and results in the change of an Asparagine to a Histidine (AAC>CAC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Asn619His was not observed at a significant allele frequency in large population cohorts (Lek 2016). Since Asparagine and Histidine differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Asn619His is not located in a known functional domain. In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available information, it is unclear whether ATM Asn619His is pathogenic or benign. We consider it to be a variant of uncertain significance.
