GeneDx RCV000484817 SCV000569413 uncertain significance not provided 2016-02-19 criteria provided, single submitter clinical testing This variant is denoted POLD1 c.244C>G at the cDNA level, p.Pro82Ala (P82A) at the protein level, and results in the change of a Proline to an Alanine (CCC>GCC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. POLD1 Pro82Ala 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. POLD1 Pro82Ala occurs at a position that is conserved across species and is not located in a known functional domain (Tahirov 2009, Preston 2010). In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available evidence, it is unclear whether POLD1 Pro82Ala is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
