GeneDx RCV000236715 SCV000293060 uncertain significance not provided 2015-08-05 criteria provided, single submitter clinical testing This variant is denoted ATM c.3334C>G at the cDNA level, p.Pro1112Ala (P1112A) at the protein level, and results in the change of a Proline to an Alanine (CCT>GCT). This variant has been observed in at least one individual with a history of ovarian cancer (Kanchi 2014). ATM Pro1112Ala was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Proline and Alanine differ in some properties, this is considered a semi-conservative amino acid substitution. ATM Pro1112Ala occurs at a position that is conserved across species and is located within a region that interacts with beta-adaptin (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 Pro1112Ala is pathogenic or benign. We consider it to be a variant of uncertain significance.
