GeneDx RCV000294687 SCV000329735 pathogenic not provided 2015-12-29 criteria provided, single submitter clinical testing The c.3084delG pathogenic variant in the CC2D2A gene has been reported previously in association with Meckel-Gruber syndrome, when present in the homozygous state or when in trans with another pathogenic variant (Tallila et al., 2009; Mougou-Zerelli et al., 2009; Hopp et al., 2011). The c.3084delG variant causes a frameshift starting with codon Lysine 1029, changes this amino acid to an Arginine residue, and creates a premature Stop codon at position 3 of the new reading frame, denoted p.Lys1029ArgfsX3. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.3084delG variant was not observed in approximately 6,200 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret c.3084delG as a pathogenic variant.
