GeneDx RCV000483764 SCV000568236 likely pathogenic not provided 2017-07-12 criteria provided, single submitter clinical testing This five base pair deletion has been reported previously in the Human Gene Mutation Database and the Arrhythmogenic Right Ventricular Cardiomyopathy database (Stenson et al., 2014; Van et al., 2009). The c.1440_1444delTCCCA variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant causes a shift in reading frame starting at codon Asparagine 480, changing it to a Lysine, and creating a premature stop codon at position 20 of the new reading frame, denoted p.Asn480LysfsX20. This variant is expected to result in either an abnormal, truncated protein product or loss of protein from this allele through nonsense-mediated mRNA decay. Other frameshift variants in the PKP2 gene have been reported in HGMD in association with ARVC (Stenson et al., 2014).
