GeneDx RCV000481336 SCV000567909 uncertain significance not provided 2015-09-15 criteria provided, single submitter clinical testing This variant is denoted ATM c.1336C>A at the cDNA level, p.Gln446Lys (Q446K) at the protein level, and results in the change of a Glutamine to a Lysine (CAG>AAG). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Gln446Lys was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Glutamine and Lysine differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Gln446Lys occurs at a position that is not conserved and is not located in a known functional domain (Stracker 2013, Tavtigian 2009). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether ATM Gln446Lys is pathogenic or benign. We consider it to be a variant of uncertain significance.
