GeneDx RCV000406792 SCV000330762 likely pathogenic not provided 2016-08-24 criteria provided, single submitter clinical testing This duplication of one nucleotide in APC is denoted c.800dupG at the cDNA level and p.Glu268ArgfsX9 (E268RfsX9) at the protein level. The normal sequence, with the base that is duplicated in braces, is GTGG[G]AGAA. The duplication causes a frameshift which changes a Glutamic Acid to an Arginine at codon 268, and creates a premature stop codon at position 9 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. Based on the currently available evidence, we consider this duplication to be a likely pathogenic variant.
