GeneDx RCV000183718 SCV000236196 likely pathogenic not provided 2012-07-02 criteria provided, single submitter clinical testing p.Leu844Pro (CTG>CCG): c.2531 T>C in exon 13 of the PKP2 gene (NM_004572.3). The Leu844Pro variant in the PKP2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Leu844Pro results in a semi-conservative amino acid substitution of one non-polar residue for another at a position that is conserved across species. In silico analysis predicts Leu844Pro is probably damaging to the protein structure/function. A mutation in a nearby residue (Leu847Pro) has been reported in association with ARVC, further supporting the functional importance of this region of the protein. Furthermore, the NHLBI ESP Exome Variant Server reports Leu844Pro was not observed in approximately 5,000 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. In summary, while Leu844Pro is a good candidate for a disease-causing mutation, with the clinical and molecular information available at this time we cannot unequivocally determine the clinical significance of this variant. The variant is found in ARVC panel(s).
