GeneDx RCV000482235 SCV000571313 uncertain significance not provided 2016-08-10 criteria provided, single submitter clinical testing This deletion of 23 nucleotides in POLD1 is denoted c.2412_2434del23 at the cDNA level and p.Ser805AlafsX46 (S805AfsX46) at the protein level. The surrounding sequence is TTAT[del23]TGCT. The deletion causes a frameshift which changes a Serine to an Alanine at codon 805, and creates a premature stop codon at position 46 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. However, while some missense variants in POLD1 have been recognized as an underlying cause of Polymerase Proofreading-Associated Polyposis (PPAP), there are no data at this time to support that loss-of-function variants confer the same cancer risks. We therefore consider this variant to be of uncertain significance with respect to cancer.
